1Municipal wastewater treatment in China:Development history and future perspectives显示文摘China has the world's largest and still growing wastewater sector and water market,thus its future development will have profound influence on the world.The high-speed development of China's wastewater sector over the past 40 years has forged its global leading treatment capacity and innovation ability.However,many problems were left behind,including underdeveloped sewers and sludge disposal facilities,low sustainability of the treatment processes,questionable wastewater treatment plant(WWTP)effluent discharge standards,and lacking global thinking on harmonious development between wastewater management,human society and the nature.Addressing these challenges calls for fundamental changes in target design,policy and technologies.In this mini-review,we revisit the development history of China's municipal wastewater management and identify the remaining challenges.Also,we highlight the future needs of sustainable development and exploring China's own wastewater management path,and outlook the future from several aspects including targets of wastewater management,policies and technologies,especially the new concept WWTP.Furthermore,we envisage the establishment of new-generation WWTPs with the vision of turning WWTP from a site of pollutant removal into a plant of energy,water and fertilizer recovery and an integrated part urban ecology in China.Jiuhui Qu Hongchen Wang Kaijun Wang Gang Yu Bing Ke Han-Qing Yu Hongqiang Ren Xingcan Zheng Ji Li Wen-Wei Li Song Gao Hui Gong 2019Frontiers of Environmental Science & Engineering2019,13,6:13
2Carbon pools and fluxes in the China Seas and adjacent oceans显示文摘The China Seas include the South China Sea, East China Sea, Yellow Sea, and Bohai Sea. Located off the Northwestern Pacific margin, covering 4700000 km^2 from tropical to northern temperate zones, and including a variety of continental margins/basins and depths, the China Seas provide typical cases for carbon budget studies. The South China Sea being a deep basin and part of the Western Pacific Warm Pool is characterized by oceanic features; the East China Sea with a wide continental shelf, enormous terrestrial discharges and open margins to the West Pacific, is featured by strong cross-shelf materials transport; the Yellow Sea is featured by the confluence of cold and warm waters; and the Bohai Sea is a shallow semiclosed gulf with strong impacts of human activities. Three large rivers, the Yangtze River, Yellow River, and Pearl River, flow into the East China Sea, the Bohai Sea, and the South China Sea, respectively. The Kuroshio Current at the outer margin of the Chinese continental shelf is one of the two major western boundary currents of the world oceans and its strength and position directly affect the regional climate of China. These characteristics make the China Seas a typical case of marginal seas to study carbon storage and fluxes. This paper systematically analyzes the literature data on the carbon pools and fluxes of the Bohai Sea,Yellow Sea, East China Sea, and South China Sea, including different interfaces(land-sea, sea-air, sediment-water, and marginal sea-open ocean) and different ecosystems(mangroves, wetland, seagrass beds, macroalgae mariculture, coral reefs, euphotic zones, and water column). Among the four seas, the Bohai Sea and South China Sea are acting as CO_2 sources, releasing about0.22 and 13.86–33.60 Tg C yr^(-1) into the atmosphere, respectively, whereas the Yellow Sea and East China Sea are acting as carbon sinks, absorbing about 1.15 and 6.92–23.30 Tg C yr^(-1) of atmospheric CO_2, respectively. Overall, if only the CO_2 exchange at the sea-air interface is considered, the Chinese marginal seas appear to be a source of atmospheric CO_2, with a net release of 6.01–9.33 Tg C yr^(-1), mainly from the inputs of rivers and adjacent oceans. The riverine dissolved inorganic carbon (DIC) input into the Bohai Sea and Yellow Sea, East China Sea, and South China Sea are 5.04, 14.60, and 40.14 Tg C yr^(-1),respectively. The DIC input from adjacent oceans is as high as 144.81 Tg C yr^(-1), significantly exceeding the carbon released from the seas to the atmosphere. In terms of output, the depositional fluxes of organic carbon in the Bohai Sea, Yellow Sea, East China Sea, and South China Sea are 2.00, 3.60, 7.40, and 5.92 Tg C yr^(-1), respectively. The fluxes of organic carbon from the East China Sea and South China Sea to the adjacent oceans are 15.25–36.70 and 43.93 Tg C yr^(-1), respectively. The annual carbon storage of mangroves, wetlands, and seagrass in Chinese coastal waters is 0.36–1.75 Tg C yr^(-1), with a dissolved organic carbon(DOC) output from seagrass beds of up to 0.59 Tg C yr^(-1). Removable organic carbon flux by Chinese macroalgae mariculture account for 0.68 Tg C yr^(-1) and the associated POC depositional and DOC releasing fluxes are 0.14 and 0.82 Tg C yr^(-1), respectively. Thus, in total, the annual output of organic carbon, which is mainly DOC, in the China Seas is 81.72–104.56 Tg C yr^(-1). The DOC efflux from the East China Sea to the adjacent oceans is 15.00–35.00 Tg C yr^(-1). The DOC efflux from the South China Sea is 31.39 Tg C yr^(-1). Although the marginal China Seas seem to be a source of atmospheric CO_2 based on the CO_2 flux at the sea-air interface, the combined effects of the riverine input in the area, oceanic input, depositional export,and microbial carbon pump(DOC conversion and output) indicate that the China Seas represent an important carbon storage area.Nianzhi JIAO Yantao LIANG Yongyu ZHANG Jihua LIU Yao ZHANG Rui ZHANG Meixun ZHAO Minhan DAI Weidong ZHAI Kunshan GAO Jinming SONG Dongliang YUAN Chao LI Guanghui LIN Xiaoping HUANG Hongqiang YAN Limin HU Zenghu ZHANG Long WANG Chunjie CAO Yawei LUO Tingwei LUO Nannan WANG Hongyue DANG Dongxiao WANG Si ZHANG 2018Science China Earth Sciences2018,61,11:12
3深地震反射剖面揭露青藏高原陆-陆碰撞与地壳生长的深部过程显示文摘印度板块与亚洲板块的碰撞使喜马拉雅-青藏高原隆升,地壳增厚和生长扩展。探测青藏高原深部结构,揭露两个大陆如何碰撞,碰撞如何使大陆变形的过程,是全球关切的科学奥秘。深地震反射剖面探测是打开这个科学奥秘的最有效途径之一。20多年来,运用这项高技术探测到青藏高原巨厚地壳的精细结构,攻克了难以得到下地壳和Moho清晰结构的技术瓶颈,揭露了陆陆碰撞过程。本文在探测研究成果基础上,从青藏高原南北东西对比,再到高原腹地,系统地综述了青藏高原之下印度板块与亚洲板块碰撞俯冲的深部行为。印度地壳在高原南缘俯冲在喜马拉雅造山带之下,亚洲板块的阿拉善地块岩石圈在北缘向祁连山下俯冲,祁连山地壳向外扩展,塔里木地块与高原西缘的西昆仑发生面对面的碰撞,在高原东缘发现龙日坝断裂而不是龙门山断裂是扬子板块的西缘边界,高原腹地Moho薄而平坦,岩石圈伸展垮塌。多条深反射剖面揭露了在雅鲁藏布江缝合带下印度板块与亚洲板块碰撞的行为,印度地壳不仅沿雅鲁藏布江缝合带存在由西向东的俯冲角度变化,而且其向北行进到拉萨地体内部的位置也不同。在缝合带中部,显示印度地壳上地壳与下地壳拆离,上地壳向北仰冲,下地壳向北俯冲,并在俯冲过程发生物质的回返与构造叠置,使印度地壳减薄,喜马拉雅地壳加厚。俯冲印度地壳前缘与亚洲地壳碰撞后沉入地幔,处于亚洲板块前缘的冈底斯岩基与特提斯喜马拉雅近于直立碰撞,冈底斯下地壳呈部分熔融状态,近乎透明的弱反射和局部出现的亮点反射,以及近于平的Moho都反映出亚洲板块南缘的伸展构造环境。GAO Rui ZHOU Hui GUO Xiaoyu LU Zhanwu LI Wenhui WANG Haiyan LI Hongqiang XIONG Xiaosong HUANG Xingfu XU Xiao 2021地学前缘2021,28,5:4

7Three Indication Variables and Their Performance for the Troubled-Cell Indicator using K-Means Clustering显示文摘In Zhu,Wang and Gao(SIAM J.Sci.Comput.,43(2021),pp.A3009–A3031),we proposed a new framework of troubled-cell indicator(TCI)using K-means clustering and the numerical results demonstrate that it can detect the troubled cells accurately using the KXRCF indication variable.The main advantage of this TCI framework is its great potential of extensibility.In this follow-up work,we introduce three more indication variables,i.e.,the TVB,Fu-Shu and cell-boundary jump indication variables,and show their good performance by numerical tests to demonstrate that the TCI framework offers great flexibility in the choice of indication variables.We also compare the three indication variables with the KXRCF one,and the numerical results favor the KXRCF and the cell-boundary jump indication variables.Zhihuan Wang Zhen Gao Haiyun Wang Qiang Zhang Hongqiang Zhu 2023Advances in Applied Mathematics and Mechanics2023,15,2:1

12The valuation of China’s environmental degradation from 2004 to 2017显示文摘This paper aims to evaluate the cost of environmental degradation by adopting the conventional environmental economic methodology in China from 2004 to 2017 and summarize the change in both the causes and costs of China’s environmental degradation.Results from this study revealed the following:i.The environmental degradation cost in China increased from 511 billion yuan to 1,892 billion yuan from 2004 to 2017,and its share in the GDP decreased from 3.05% to 2.23%;ii.The environmental degradation cost growth rate was lower than the GDP growth rate.The environmental degradation cost growth rate decreased sharply,by dropping from 10% in 2014 to 2% in 2017.The environmental benefits of industrial transformation have emerged;iii.The provinces of Shandong,Hebei,Jiangsu,Henan,and Guangdong had the highest environmental degradation costs.The annual average growth rate of the environmental degradation costs in Jiangsu,Guangdong,and Zhejiang were lower than their growth rate of the GDP respectively;iv.Consideration of environmental degradation cost in decision-making could contribute to the high-quality development of China.Guoxia Ma Fei Peng Weishan Yang Gang Yan Shuting Gao Xiafei Zhou Ji Qi Dong Cao Yue Zhao Wen Pan Hongqiang Jiang Hong Jing Guangxia Dong Minxue Gao Jingbo Zhou Fang Yu Jinnan Wang 2020Environmental Science and Ecotechnology2020,,1:1
13Using large dynamite shots to image the structure of the Moho from deep seismic reflection experiment between the Sichuan basin and Qinling orogen显示文摘The Qinling orogen was formed as a result of the collision between the North and South China blocks. The Qinling orogen represents the location at which the southern and northern parts of the Chinese mainland collided, and it's also the intersection of the Central China orogen and the north-south tectonic belt. There is evidence of strong deformation in this orogen, and it has had a long and complex geological history. We investigated the structure of the Moho in the southern Qinling orogen using large dynamite shot imaging techniques. By integrating the analysis of the single-shot and the move-out corrections profile, we determined the structure of the Moho beneath the northern Dabashan thrust belt and the southern Qinling orogen, including the mantle suture beneath Fenghuang mountain. The Moho is divided into two parts by the mantle suture zone beneath Fenghuang mountain:(1) from Ziyang to Hanyin, the north-dipping Moho is at about45–55 km depth and the depth increases rapidly; and(2)from Hanyin to Ningshan, the south-dipping Moho is at about 40–45 km depth and shallows slowly. The mantle suture is located beneath Fenghuang mountain, and the Moho overlaps at this location: the shallower Moho is connected to the northern part of China, and the deeper Moho is connected to the southern part. This may indicate that the lithosphere in the Sichuan basin subducts to the Qinling block and that the subduction frontier reaches at least as far as Fenghuang mountain.Hongqiang Li Rui Gao Haiyan Wang Wenhui Li Xiaosong Xiong 2016Earthquake Science2016,29,6:1
14A High-OrderDiscontinuous GalerkinMethod for the Two-Dimensional Time-Domain Maxwell’s Equations on Curved Mesh显示文摘In this paper,a DG(Discontinuous Galerkin)method which has been widely employed in CFD(Computational Fluid Dynamics)is used to solve the twodimensional time-domain Maxwell’s equations for complex geometries on unstructured mesh.The element interfaces on solid boundary are treated in both curved way and straight way.Numerical tests are performed for both benchmark problems and complex cases with varying orders on a series of grids,where the high-order convergence in accuracy can be observed.Both the curved and the straight solid boundary implementation can give accurate RCS(Radar Cross-Section)results with sufficiently small mesh size,but the curved solid boundary implementation can significantly improve the accuracy when using relatively large mesh size.More importantly,this CFD-based high-order DG method for the Maxwell’s equations is very suitable for complex geometries.Hongqiang Lu Yida Xu Yukun Gao Wanglong Qin Qiang Sun 2016Advances in Applied Mathematics and Mechanics2016,8,1:1
15The first 2D organic-inorganic hybrid relaxor-ferroelectric single crystal显示文摘Inorganic relaxor ferroelectric solid solution single crystals are spurring new generations of high performance electromechanical devices,including transducers,sensors,and actuators,due to their ultrahigh electric field induced strain,large piezoelectric constant,high electromechanical coupling factor and low dielectric loss.However,relaxor ferroelectric single crystals found in organic-inorganic hybrid perovskites are very limited,but achieving these superior properties in them will be of great significance in the design of modern functional materials.Fortunately,here the first two-dimensional(2D)organic-inorganic hybrid relaxor ferroelectric single crystal,[Br(CH_(2))_(3)NH_(3)]_(2)PbBr_(4)(BPA_(2)-PbBr_(4),BPA=3-bromopropylamine),achieves some of superior properties.Interestingly,BPA_(2)-PbBr_(4)reveals a successive relaxor ferroelectric-ferroelectric-paraelectric phase transitions accompanying by a large degree of relaxationΔT_(relax)=61 K and ultralow energy loss(tanδ<0.001).Meanwhile,it exhibits a superior second harmonic generation(SHG)effect with maximum value accounts for 95%of the standard KDP due to great deformation of structure(3.2302×10^(-4)).In addition,temperature dependent luminescence spectra(80-415 K)exhibit fluorescence and phosphorescence overlapping emission originated from inorganic and organic components with the nanosecond-scale short lifetime and the millisecond-scale long lifetime,respectively,and the color of the emitted light is continuously adjustable,which is the first to achieve luminescence and relaxor ferroelectricity compatibility.Wenjuan Wei Hongqiang Gao Ming Fang Yang Yang Yan Guan Yen Wei Yunzhi Tang 2023Science China Chemistry2023,66,2:0

17Rational design of imine-linked three-dimensional mesoporous covalent organic frameworks with bor topology显示文摘Three-dimensional(3D)covalent organic frameworks(COFs)possess great potential applications in various fields.Constructing 3D COFs with large pore sizes is extremely challenging due to the interpenetration and collapse.Herein,we report a series of crystalline imine-linked 3D COFs(3D-bor-COF-1,3D-borCOF-2,3D-bor-COF-3)with mesoporous channels through rationally designing the topology configuration.These 3D-bor-COFs display permanent porosity and Brunauer–Emmett–Teller(BET)surfaces of 3205.5,1752.7,and 2077.3 m2 g−1(SLangmuir=4277.7,2480.3,and 2698.0 m2 g−1),respectively.The pore sizes of 3Dbor-COFs were confirmed by the lattice fringes from high-resolution transmission electron microscopy,as well as structural simulation and nitrogen adsorption isotherm analysis.3D-bor-COFs display large pore sizes(3.8 nm for 3D-borCOF-3),which is among the highest record of 3D COFs.Owing to the unstackedaromatic pore environment and high specific surface area,3D-bor-COFs display excellent adsorption capacity for benzene vapor(1203.9 mg g−1 for 3D-bor-COF-3)under 298 K,which is three times higher than that of the best-reported 2D COF.This work not only provides inspiration for designing 3D mesoporous imineCOFs,but also demonstrates a strategy for constructing aromatics adsorption materials.Zonglong Li Chouhung Hsueh Zhuozhuo Tang Jia Chen Xiaolin Wang Hao Cui Yang Yang Xiaodan Wang Dongsheng Ren Hongqiang Gao Mingyang Li Hong Xu Xiangming He 2022SusMat2022,2,2:0
