| 1 | Effect of viscosity,basicity and organic content of composite flocculant on the decolorization performance and mechanism for reactive dyeing wastewater显示文摘A coagulation/flocculation process using the composite flocculant polyaluminum chloride-epichlorohydrin dimethylamine (PACEPI-DMA) was employed for the treatment of an anionic azo dye (Reactive Brilliant Red K-2BP dye).The effect of viscosity (η),basicity (B=[OH]/[Al]) and organic content (WP) on the flocculation performance as well as the mechanism of PAC-EPI-DMA flocculant were investigated.The η was the key factor affecting the dye removal efficiency of PAC-EPI-DMA.PAC-EPI-DMA with an intermediate η (2400 mPa·sec) gave higher decolorization efficiency by adsorption bridging and charge neutralization due to the co-effect of PAC and EPI-DMA polymers.The W P of the composite flocculant was a minor important factor for the flocculation.The adsorption bridging of PAC-EPI-DMA with η of 300 or 4300 mPa·sec played an important role with the increase of W P,whereas the charge neutralization of them was weaker with the increase of W P.There was interaction between W P and B on the removal of reactive dye.The composite flocculant with intermediate viscosity and organic content was effective for the treatment of reactive dyeing wastewater,which could achieve high reactive dye removal efficiency with low organic dosage. | Yuanfang Wang Baoyu Gao Qinyan Yue Yan Wang | 2011 | Journal of Environmental Sciences2011，23，10： | 33 |
| 2 | Interplay between the Indonesian Throughflow and the South China Sea Throughflow显示文摘Analysis both based on the wind stress and ocean assimilation dataset shows that the interannual variability of the Indonesian Throughflow and the South China Sea (Luzon Strait) Throughflow is out of phase. Wind anomaly forcing in the equatorial Pacific plays an important role in setting up this phase relation. During El Ni o events, the westerly wind bursts intensify the Northern Equator Current and induce a northward shift of its bifurcation point. As a result, the partition of volume transport between the Kuroshio and the Mindanao Current is changed, with the Kuroshio transport decreased and the Mindanao Current increased. The undershooting/overshooting phenomena occur at the Luzon Strait and the Sulawesi-Mindanao passage, caused by variability of these two currents. Water transport from the Pacific to the South China Sea increases with the Kuroshio transport decreased, and transport from the Pacific to the Indian Ocean decreases with the Mindanao Current transport increased. The situation is reversed during La Ni a. Therefore, the ocean dynamic meaning is profound to study the interannual variability relationship between the Indonesian Throughflow and the Luzon Strait Throughflow. | LIU Qinyan HUANG Ruixin WANG Dongxiao XIE Qiang HUANG Qizhou | 2006 | Chinese Science Bulletin2006，51，B12： | 24 |
| 3 | Performance of dithiocarbamate-type flocculant in treating simulated polymer flooding produced water显示文摘Produced water from polymer flooding is difficult to treat due to its high polymer concentration,high viscosity,and emulsified characteristics.The dithiocarbamate flocculant,DTC (T403),was prepared by the amine-terminated polyoxypropane-ether compound known as Jeffamine-T403.The product was characterized by IR spectra and elemental analysis.The DTC agent chelating with Fe 2+ produced a network polymer matrix,which captured and removed oil droplets efficiently.Oil removal by the flocculent on simulated produced water with 0,200,500,900 mg/L of partially hydrolyzed polyacrylamide (HPAM) was investigated for aspects of effectiveness of DTC (T403) dosage and concentrations of HPAM and Fe 2+ ions in the wastewater.Results showed that HPAM had a negative influence on oil removal efficiency when DTC (T403) dosage was lower than 20 mg/L.However,residual oil concentrations in tested samples with different concentrations of HPAM all decreased below 10 mg/L when DTC (T403) dosage reached 30 mg/L.The concentration of Fe 2+ in the initial wastewater had a slight effect on oil removal at the range of 2-12 mg/L.Results showed that Fe 3+ could not be used in place of Fe 2+ as Fe 3+ could not react with DTC under flocculated conditions.The effects of mineral salts ions were also investigated. | Baoyu Gao | 2011 | Journal of Environmental Sciences2011，23，1： | 18 |

| 5 | Effect of six kinds of scale inhibitors on calcium carbonate precipitation in high salinity wastewater at high temperatures显示文摘Precipitation of calcium carbonate(Ca CO3) scale on heat transfer surfaces is a serious and expensive problem widely occurring in numerous industrial processes. In this study, we compared the scale inhibition effect of six kinds of commercial scale inhibitors and screened out the best one(scale inhibitor SQ-1211) to investigate its scale inhibition performance in highly saline conditions at high temperature through static scale inhibition tests. The influences of scale inhibitor dosage, temperature, heating time and p H on the inhibition efficiency of the optimal scale inhibitor were investigated. The morphologies and crystal structures of the precipitates were characterized by Scanning Electron Microscopy and X-ray Diffraction analysis. Results showed that the scale inhibition efficiency of the optimal scale inhibitor decreased with the increase of the reaction temperature. When the concentration of Ca2+was 1600 mg/L, the scale inhibition rate could reach 90.7% at 80°C at p H 8. The optimal scale inhibitor could effectively retard scaling at high temperature. In the presence of the optimal scale inhibitor, the main crystal structure of Ca CO3 changed from calcite to aragonite. | Xiaochen Li Baoyu Gao Qinyan Yue Defang Ma Hongyan Rong Pin Zhao Pengyou Teng | 2015 | Journal of Environmental Sciences2015，27，3： | 15 |
| 6 | U-Pb dating of zircon from the Central Zone of the East Kunlun Orogen and its implications for tectonic evolution显示文摘LA-ICP-MS and SHRIMP U-Pb dating of zircons from orthogneisses and amphibolite from the Central Zone of the Kunlun Orogen is reported in this paper. One orthogneiss sample has metamorphic zircons yielding weighted average 206Pb/238U age of 517.0 +5.0/-6.0 Ma, and the other orthogneiss sample con- tains zircons with inherited magmatic cores giving three population 207Pb/206Pb ages of 955 Ma, 895 Ma and 657 Ma for the magmatic protolith, and metamorphic recrystallized rims with peak 206Pb/238U ages of 559 +12/?17 Ma and 516 ± 13 Ma. The amphibolite yielded three populations of weighted average 206Pb/238U age of 482.0 +10/?8.0 Ma, 516.2 ± 5.8 Ma and 549 ± 10 Ma for the metamorphic zircons. These dating results recorded the tectonothermal events that occurred in the early Paleozoic and the Pre- cambrian time. The records of the Cambrian magmatic-metamorphic event in the Qinling Orogen, the Altyn Tagh belt, north margin of the Qaidam Block and the Kunlun Orogen suggest that continental assembly probably occurred in the early evolutionary history of the Proto-Tethys. | CHEN NengSong SUN Min WANG QinYan ZHANG KeXin WAN YuSheng CHEN HaiHong | 2008 | Science China Earth Sciences2008，51，7： | 13 |
| 7 | Coagulation behavior and floc properties of compound bioflocculant–polyaluminum chloride dual-coagulants and polymeric aluminum in low temperature surface water treatment显示文摘This study was intended to compare coagulation behavior and floc properties of two dualcoagulants polyaluminum chloride–compound bioflocculant(PAC–CBF)(PAC dose first) and compound bioflocculant–polyaluminum chloride(CBF–PAC)(CBF dose first) with those of PAC alone in low temperature drinking water treatment. Results showed that dualcoagulants could improve DOC removal efficiency from 30% up to 34%. Moreover, CBF contributed to the increase of floc size and growth rate, especially those of PAC–CBF were almost twice bigger than those of PAC. However, dual-coagulants formed looser and weaker flocs with lower breakage factors in which fractal dimension of PAC–CBF flocs was low which indicates a looser floc structure. The floc recovery ability was in the following order:PAC–CBF > PAC alone > CBF–PAC. The flocculation mechanism of PAC was charge neutralization and enmeshment, meanwhile the negatively charged CBF added absorption and bridging effect. | Xin Huang Shenglei Sun Baoyu Gao Qinyan Yue Yan Wang Qian Li | 2015 | Journal of Environmental Sciences2015，27，4： | 11 |
| 8 | Recursive super-convergence computation for multi-dimensional problems via one-dimensional element energy pro jection technique显示文摘This paper presents a strategy for computation of super-convergent solutions of multi-dimensional problems in the finite element method(FEM) by recursive application of the one-dimensional(1D) element energy projection(EEP) technique. The main idea is to conceptually treat multi-dimensional problems as generalized 1D problems,based on which the concepts of generalized 1D FEM and its consequent EEP formulae have been developed in a unified manner. Equipped with these concepts, multi-dimensional problems can be recursively discretized in one dimension at each step, until a fully discretized standard finite element(FE) model is reached. This conceptual dimension-bydimension(D-by-D) discretization procedure is entirely equivalent to a full FE discretization. As a reverseD-by-D recovery procedure, by using the unified EEP formulae together with proper extraction of the generalized nodal solutions, super-convergent displacements and first derivatives for two-dimensional(2D) and three-dimensional(3D) problems can be obtained over the domain. Numerical examples of 3D Poisson's equation and elasticity problem are given to verify the feasibility and effectiveness of the proposed strategy. | Si YUAN Yue WU Qinyan XING | 2018 | Applied Mathematics and Mechanics(English Edition)2018，39，7： | 11 |
| 9 | Progress of regional oceanography study associated with western boundary current in the South China Sea显示文摘Recent progress of physical oceanography in the South China Sea (SCS) associated with the western boundary current (WBC) and eddies is reviewed in this paper. It includes Argo observations of the WBC, eddy detection in the WBC based on satellite images, cross-continental shelf exchange in the WBC, eddy-current interaction, interannual variability of the WBC, air-sea interaction, the SCS throughflow (SCSTF), among others. The WBC in the SCS is strong, and its structure, variability and dynamic processes on seasonal and interannual time scales are yet to be fully understood. In this paper, we summarize progresses on the variability of the WBC, eddy-current interaction, air-sea interaction, and the SCSTF achieved in the past few years. Firstly, using the drifting buoy observations, we point out that the WBC becomes stronger and narrower after it reaches the central Vietnam coast. The possible mechanisms influencing the ocean circulation in the northern SCS are discussed, and the dynamic mechanisms that induce the countercurrent in the region of northern branch of WBC in winter are also studied quantitatively using momentum balance. The geostropic component of the WBC was diagnosed using the ship observation along 18°N, and we found that the WBC changed significantly on interannual time scale. Secondly, using the ship observations, two anti-cyclonic eddies in the winter of 2003/2004 in the northern SCS, and three anti-cyclonic eddies in the summer of 2007 along 18°N were studied. The results show that the two anti-cyclonic eddies can propagate southwestward along the continental shelf at the speed of first Rossby wave (~0.1 ms-1 ) in winter, and the interaction between the three anti-cyclonic eddies in summer and the WBC in the SCS is preliminarily revealed. Eddies on the continental shelf of northern SCS propagated southeastward with a maximum speed of 0.09 ms-1 , and those to the east of Vietnam coast had the largest kinetic energy, both of which imply strong interaction between eddy activity and WBC in the SCS. Thirdly, strong intraseasonal variability (ISV) of sea surface temperature (SST) near the WBC regions was found, and the ISV signal of SST in winter weakens the ISV signal of latent heat flux by 20%. Fourthly, the long-term change of SCSTF volume transport and its connection with the ocean circulation in the Pacific were discussed. | WANG DongXiao LIU QinYan XIE Qiang HE ZhiGang ZHUANG Wei SHU YeQiang XIAO XianJun HONG Bo WU XiangYu SUI DanDan | 2013 | Chinese Science Bulletin2013，58，11： | 10 |
| 10 | Performance of bimetallic nanoscale zero-valent iron particles for removal of oxytetracycline显示文摘In this study, bimetallic nanoscale zero-valent iron particles(nZVI), including copper/nanoscale zero-valent iron particles(Cu/nZVI) and nickel/nanoscale zero-valent iron particles(Ni/nZVI), were synthesized by one-step liquid-phase reduction and applied for oxytetracycline(OTC) removal. The effects of contact time and initial p H on the removal efficiency were studied. The as-prepared nanoscale particles were characterized by scanning electron microscopy(SEM), energy dispersive spectroscopy(EDS) and X-ray diffraction(XRD). Finally, the degradation mechanisms of OTC utilizing the as-prepared nanoparticles were investigated by using X-ray photoelectron spectroscopy(XPS) and mass spectrometry(MS). Cu/n ZVI presented remarkable ability for OTC degradation and removed71.44% of OTC(100 mg/L) in 4 hr, while only 62.34% and 31.05% of OTC was degraded by Ni/nZVI and nZVI respectively. XPS and MS analysis suggested that OTC was broken down to form small molecules by ·OH radicals generated from the corrosion of Fe0. Cu/nZVI and Ni/n ZVI have been proved to have potential as materials for application in OTC removal because of their significant degradation ability toward OTC. | Yuwei Wu Qinyan Yue Yuan Gao Zhongfei Ren Baoyu Gao | 2018 | Journal of Environmental Sciences2018，30，7： | 9 |
| 11 | Zircon Hf Isotopes and Geochemistry of the Early Paleoproterozoic High-Sr Low-Y Quartz-Diorite in the Quanji Massif,NW China:Crustal Growth and Tectonic Implications显示文摘The metamorphosed Early Paleoproterozoic granitoids in the Quanji massif,Northwestern China provide constraints for relationship between the Tarim Craton and North China Craton.Among granitoids batholiths,rocks of the Mohe quartz-diorite show typically adakitic geochemical characteristics,with medium K2O/Na2O ratios(0.56–1.17)and high Sr(519–619 ppm)low Y(9.37–20.40 ppm)and Yb(0.97–1.77 ppm)concentrations.The rocks haveεNd(t)values between+2.4and+4.4 and depleted mantle Nd model ages of 2.43–2.59 Ga.The magmatic zircons have positiveεHf(t)values ranging from+0.40 to+7.60 and depleted mantle Hf model ages of 2.43–2.70 Ga,with major peaks at^2.54 and^2.65 Ga.The geochemical and Nd-Hf isotopic characteristics indicate that the Mohe quartz-dioritic rocks might be formed by partial melting of high-pressure metamorphosed juvenile crustal rocks in post-orogenic extensional regime in the Early Paleoproterozoic.It suggests that important crustal growth occurred in the Quanji massif and the Tarim Craton at^2.4 and 2.5–2.7 Ga.The Quanji massif and Tarim Craton might share a similar crustal evolution history with the North China Craton in the Neoarchean. | Songlin Gong Nengsong Chen Hongyan Geng Min Sun Lu Zhang Qinyan Wang | 2014 | Journal of Earth Science2014，25，1： | 8 |
| 12 | Adsorptive removal of phosphate by the bimetallic hydroxide nanocomposites embedded in pomegranate peel显示文摘This study aimed to fabricate new and effective material for the efficiency of phosphate adsorption.Two types of adsorbent materials,the zirconium hydroxides embedded in pomegranate peel(Zr/Peel)and zirconium-lanthanum hydroxides embedded in pomegranate peel(Zr-La/Peel)were developed.Scanning electronic microscopy(SEM),x-ray photoelectron spectroscopy(XPS)and x-ray diffraction(XRD)were evaluated to give insight into the physicochemical properties of these adsorbents.Zr-La/Peel exceeded the adsorption efficiency of Zr/Peel adsorbents in batch adsorption experiments at the same pH level.The peel as a host can strive to have a strong'shielding effect'to increase the steadiness of the entrenched Zr and La elements.La and Zr are hydroxide metals that emit many hydrogen ions during the hydrolysis reaction,which contribute to protonation and electrostatic attraction.The highest adsorption capacity of La-Zr/Peel for phosphate was calculated to be40.21 mg/g,and pseudo second-order equation is very well fitted for kinetic adsorption.Phosphate adsorption efficiency was reduced by an increase of pH.With the background of coexisting Cl-,little effect on adsorption efficiency was observed,while adsorption capacities were reduced by almost 20-30%with the coexistence of SO42-,NO3-and humic acid(HA). | Muhammad Akram Xing Xu Baoyu Gao Qinyan Yue Shang Yanan Rizwan Khan Muhammad Ali Inam | 2020 | Journal of Environmental Sciences2020，32，5： | 8 |
| 13 | Novel cationic polyamidine:Synthesis,characterization,and sludge dewatering performance显示文摘In this study,a new and facile route was employed for synthesis of polyamidine with abundant cations and attractive five-membered ringlike structural unit.N-vinylformamide and acrylonitrile copolymerized firstly to form intermediates,and the intermediates were processed with hydrochloric acid to produce polyamidine.A series of polymerization conditions(e.g.polymerization time,temperature and dosage of initiator) were optimized through productivity,viscosity and cationic degree as evaluation.SEM analysis illustrated that the amidinization process could reduce the size of spaces between molecular and created compact structure,which would contribute to good flocculation performance and high viscosity.FT-IR,XPS and NMR spectra presented a rather clear structure of polyamidine.34.3%of sludge was sedimentated through the flocculation of polyamidine in the early stages.In contrast,only 6.8%of sludge was sedimentated by polyacrylamide.The moisture content in dehydrated floc could be reduced to 77.7%when 60 mg/L polyamidine was added.These results demonstrated that the polyamidine showed a great potential in the practical application of sludge dewatering. | Bo Guo Huan Yu Baoyu Gao Sen Zhang Qinyan Yue Xing Xu | 2017 | Journal of Environmental Sciences2017，29，1： | 7 |
| 14 | Fractionation of residual Al in natural water treatment from reservoir with poly-aluminum-silicate-chloride (PASiC): Effect of OH/Al, Si/Al molar ratios and initial pH显示文摘An aluminum fractionation study was conducted for a surface reservoir water treatment to understand the performance of polyaluminum-silicate-chloride (PASiC) in terms of the residual Al fractions as a function of initial pH. The coagulation performance expressed as turbidity and organic matter removal was established as supporting data. Some extra data were evaluated in terms of the residual Al ratio of the composite PASiC coagulant. The main residual Al sources were the Al fractions derived from the use of PASiC. The turbidity and organic matter removal ability was optimal at initial pH 6.00-7.00, while the concentrations of various residual Al species and the residual Al ratio of PASiC were minimal at an initial pH range of 7.00-8.00. Under the conditions of OH/Al molar ratio=2.00 and Si/Al molar ratio=0.05, PASiC had superior coagulation performance and comparatively low residual Al concentrations. The Al fraction in the composite PASiC coagulant seldom remained under such conditions. Experimental data also indicated that the suspended (filterable) Al fraction was the dominant species, and organic-bound or organo-Al complex Al was considered to be the major species of dissolved Al in water treated by PASiC coagulation. Additionally, the dissolved inorganic monomeric Al species dominated the dissolved monomeric Al fraction. | Zhonglian Yang Baoyu Gao Yan Wang Yaqin Zhao Qinyan Yue | 2012 | Journal of Environmental Sciences2012，24，11： | 7 |
| 15 | Pre-treatment of pyridine wastewater by new cathodic–anodic-electrolysis packing显示文摘A novel cathodic–anodic-electrolysis packing(CAEP) used in the treatment of pyridine wastewater was researched, which mainly consisted of 4,4′-diamino-2,2′-disulfonic acid(DSD acid) industrial iron sludge. The physical properties and morphology of the packing were studied. The CAEP was used in a column reactor during the pretreatment of pyridine wastewater. The influence of p H, hydraulic retention time(HRT), the air–liquid ratio(A/L)and the initial concentration of pyridine were investigated by measuring the removal of total organic carbon(TOC) and pyridine. The characterization results showed that the bulk density, grain density, water absorption percentage and specific surface area were 921 kg/m3,1086 kg/m3, 25% and 29.89 m^2/g, respectively; the removal of TOC and pyridine could reach50% and 58% at the optimal experimental conditions(p H = 3, HRT = 8 hr, A/L = 2). Notably,the surface of the packing was renewed constantly during the running of the filter, and the handling capacity was stable after running for three months. | Yang Jin Qinyan Yue Kunlun Yang Suqing Wu Shengjie Li Baoyu Gao Yuan Gao | 2018 | Journal of Environmental Sciences2018，30，1： | 6 |
| 16 | Zircon and Monazite Ages Constraints on Devonian Magmatism and Granulite-Facies Metamorphism in the Southern Qaidam Block:Implications for Evolution of Proto-and Paleo-Tethys in East Asia显示文摘High-temperature magma generation process and granulite-facies metamorphism can provide important information about mantle-crustal interaction and tectonic evolution. The strongly peraluminous monzonite pluton, the Jinshuikou cordierite granite on the southern margin of the Qaidam Block, can provide important information about the mantle-crustal interaction and constraints on tectonic transition from Proto-Tethys to Paleo-Tethys. This pluton develops enclaves of mafic granulite, amphibolite and quartzofeldspathic rocks, and is cut by massive monzonitic leuco-granite veins. Zircon and monazite U-Pb dating for the cordierite granite, the granulite enclaves and a massive monzonitic leuco-granite vein reveal that the cordierite granitic magma was generated from Mesoproterozoic continental crust with protolith derived from a provenance that was composed of >2.8 Ga old recycled crustal materials and recorded a ~1.7 Ga magmatic event. The continental crust underwent low-pressure granulite-facies metamorphism at ~380 Ma ago, whereas the cordierite granite magmas was generated and emplaced during 380 Ma, followed by intrusion of the massive monzonitic leuco-granite vein at circa 370–330 Ma. These data suggest that after the final closure of Proto-Tethys Ocean spreading along the southern Qaidam Block at ~420 Ma, break-off of the subducted slab or delamination of the lower crustal base and upwelling of the asthenospheric mantle beneath the southern Qaidam Block occurred before the Mid-Devonian, and that the initiation of the Paleo-Tethys tectonics might initiate near the end of Early-Carboniferous in the East Kunlun-Qaidam region, East Asia. | Jin Ba Lu Zhang Chuan He Neng-Song Chen Timothy M.Kusky Qinyan Wang Yusheng Wan Xiaoming Liu | 2018 | Journal of Earth Science2018，29，5： | 6 |
| 17 | Adsorption studies of the removal of anions from aqueous solutions onto an adsorbent prepared from wheat straw显示文摘Modified wheat straw (MWS) was prepared by the grafting of epichlorohydrin,triethylamine and ethylenediamine onto WS.The characteristics of MWS and its adsorption capacity for NO-3,PO34and Cr2O72were investigated.The results indicate that amine groups with positive charge have been introduced into the structure of MWS,and significantly increased its anion adsorption property.The functions of MWS dosage,the solution pH,the contact time and temperature have significant influence on the adsorption process,and the adsorption is well fitted with the Langmuir equation and pseudo second-order model.The maximum adsorption capacity of MWS for NO-3,PO34(P) and Cr2O27(Cr) is 53.5,62.4 and 386.2 mg g-1,respectively. | XU Xing,GAO Yue,GAO BaoYu,YUE QinYan & ZHONG QianQian School of Environmental Science and Engineering,Shandong University,Jinan 250100,China | 2010 | Science China Chemistry2010，53，6： | 6 |
| 18 | Electron microprobe chemical ages of monazite from Qinling Group in the Qinling Orogen: Evidence for Late Pan-African metamorphism?显示文摘Electron microprobe chemical dating was carried out on monazites enclosed in two gen-erations of mineral paragenesis of St + Ky + Grt and Sil + And + Grt + St, respectively, from the Qinling Group. Two different ages, 520±23 Ma and 435±9 Ma, were obtained from these monazites. This indicates that the Qinling Group experienced a metamorphism during the Early Cambrian, which is probably in response to the Late Pan-African subduction-accretion tectonothermal event. | CHEN Qiang CHEN Nengsong WANG Qinyan SUN Min WANG Xinyu LI Xiaoyan SHU Guiming | 2006 | Chinese Science Bulletin2006，51，21： | 6 |

| 20 | Purification and characterization of Al_(13) species in coagulant polyaluminum chloride显示文摘Nano-Al13 was separated and purified by four methods to investigate its characteristic,and was analyzed by Al-Ferron timed complexation spectrophotometer,27Al-NMR(nuclear magnetic resonance) ,and transmission electron microscopy(TEM) . Coagulation efficiency of nano-Al13,polyaluminum chloride(PAC) ,and AlCl3 in synthetic water were also investigated by jar test. The dynamic process and aggregation state of kaolin suspensions coagulating with nano-Al13,PAC,and AlCl3 were also investigated. The experimental results indicated that the efficiency of gel column chromatography method was the highest for separating PAC solution with low Al concentration. Ethanol and acetone method was simple and could separated PAC solution with different Al concentrations,while silicon alkylation white block column chromatography method could separate PAC solution only with low Al concentration. The SO42-/Ba2+ displacement method could separate PAC solution with high Al concentration,but extra inorganic cation and anion could be introduced into the solution during the separation. The coagulation efficiency and dynamic experimental results showed that nano-Al13 with a high positive-charged species was the main species of electric neutralization in coagulation process,and it could reduce the turbidity and increase the effiective particles collision rate efflciently in coagulation process. Its coagulation speed and the particle size of coagulant formed were of greatest value in this study. | GAO Baoyu CHU Yongbao YUE Qinyan WANG Yan | 2009 | Journal of Environmental Sciences2009，21，1： | 5 |
