| 1 | Characterization of refuse landfill leachates of three different stages in landfill stabilization process显示文摘Landfill leachates with different ages(mature leachate,11 years;semi-mature leachate,5 years;fresh leachate,under operation) were collected from Laogang Refuse Landfill,Shanghai to characterize the colloid size distribution and variations of leachate.These leachates were separated using micro-filtration and ultra-filtration into specific size fractions,i.e.,suspended particles(SP)(>1.2μm) ,coarse colloids(CC)(1.2-0.45μm) ,fine colloids(FC)(0.45μm,5 kDa/1 kDa molecular weight(MW) ) ,and dissolved organic matters(DM,<5 kDa/1 kDa MW) .The specific colloids in each size fraction were quantified and characterized through chemical oxygen demands(COD) ,total solid(TS) ,pH,NH4+-N,total organic carbon(TOC) and fixed solid(FS) .It was found that COD,NH4+-N and TS in leachate decreased significantly over ages,while pH increased.The dissolved fractions(<5 kDa/1 kDa) dominated(over 50%) in three leachates in terms of COD,and the organic matter content in dissolved fraction of leachates decreased and the inorganic matter increased as the disposal time extended,with the TOC/COD ratio 30%-7%.Dissolved fractions decreased from 82%to 40%in terms of TOC as the disposal time extended,suggested that the organic matter remained in leachate would form into middle molecular weight substances during the degradation process. | LOU Ziyang DONG Bin CHAI Xiaoli SONG Yu ZHAO Youcai ZHU Nanwen | 2009 | Journal of Environmental Sciences2009，21，9： | 9 |
| 2 | Greenhouse gas emission and its potential mitigation process from the waste sector in a large-scale exhibition显示文摘As one of the largest human activities, World Expo is an important source of anthropogenic Greenhouse Gas emission(GHG), and the GHG emission and other environmental impacts of the Expo Shanghai 2010, where around 59,397 tons of waste was generated during 184 Expo running days, were assessed by life cycle assessment(LCA). Two scenarios, i.e., the actual and expected figures of the waste sector, were assessed and compared, and 124.01 kg CO2-equivalent(CO2-eq.), 4.43 kg SO2-eq., 4.88 kg NO-3-eq., and 3509 m3 water per ton tourist waste were found to be released in terms of global warming(GW), acidification(AC),nutrient enrichment(NE) and spoiled groundwater resources(SGWR), respectively. The total GHG emission was around 3499 ton CO2-eq. from the waste sector in Expo Park, among which 86.47% was generated during the waste landfilling at the rate of 107.24 kg CO2-eq.,and CH4, CO and other hydrocarbons(HC) were the main contributors. If the waste sorting process had been implemented according to the plan scenario, around 497 ton CO2-eq.savings could have been attained. Unlike municipal solid waste, with more organic matter content, an incineration plant is more suitable for tourist waste disposal due to its high heating value, from the GHG reduction perspective. | Ziyang Lou Bernd Bilitewski Nanwen Zhu Xiaoli Chai Bing Li Youcai Zhao Peter Otieno | 2015 | Journal of Environmental Sciences2015，27，5： | 3 |
| 3 | Full-spectrum cell-free RAN for 6G systems:system design and experimental results显示文摘With distributed transceivers and scalable cooperative transmission,cell-free massive multipleinput multiple-output(CF-mMIMO)technology eliminates the“cells”of traditional mobile communications,thereby significantly improving the performance of wireless networks.CF-mMIMO is considered as a major technical tool for achieving the key performance indicators of sixth generation(6G)mobile communication systems.In this paper,a scalable implementation architecture for CF-mMIMO is proposed,based on which potential key technologies such as channel information acquisition,transceiver design,dynamic user and access point association,and novel duplexing are introduced.Finally,based on low-cost commercial access points,a CF-mMIMO testbed with 64 transmit and receive antennas is developed,and the performance of the distributed receiver design is evaluated. | Dongming WANG Xiaohu YOU Yongming HUANG Wei XU Jiamin LI Pengcheng ZHU Yanxiang JIANG Yang CAO Xinjiang XIA Ziyang ZHANG Qingji JIANG Pan WANG Dongjie LIU Kang ZHENG Mengting LOU Jing JIN Qixing WANG Jiangzhou WANG | 2023 | Science China(Information Sciences)2023，66，3： | 3 |

| 19 | Bioaerosol emissions variations in large-scale landfill region and their health risk impacts显示文摘Landfills are widely complained about due to the long-term odor and landfill gas emissions for local residents,while the bioaerosols are always neglected as another threat to on-site workers.In this study,bioaerosols samples were collected from the typical operation scenes in the large-scale modern landfill,and the emission levels of airborne bacteria,pathogenic species,and fungi were quantified and co-related.The corresponding exposure risks were assessed based on the average daily dose via inhalation and skin contact.It was found that the levels of culturable bacteria and fungi in all landfill samples were around 33–22778 CFU/m3 and 8–450 CFU/m3,and the active-working landfill area and the covered area were the maximum and minimum emission sources,respectively,meaning that the bioaerosols were mainly released from the areas related with the fresh waste operation.Acinetobacter sp.,Massilia sp.,Methylobacterium-Methylorubrum sp.and Noviherbaspirillum sp.were the main bacterial populations,with a percentage of 42.56%,89.82%,70.24%and 30.20%respectively in total bioaerosols measured.With regards to the health risk,the health risks via inhalation were the main potential risks,with four orders of magnitude higher than that of skin contact.Active-working area showed the critical point for non-carcinogenic risks,with a hazard quotient of 1.68,where 80 m protection distance is recommended for on-site worker protection,plus more careful protection measures. | Yanfeng Yang Ruina Zhang Ziyang Lou | 2022 | Frontiers of Environmental Science & Engineering2022，16，12： | 0 |
| 20 | The acceleration degradation processes of different aged refuses with the forced aeration for landfill reclamation显示文摘Forced aeration is one of the promising ways to accelerate landfill reclamation,and understanding the relation between aeration rates and waste properties is the prerequisite to implementing forced aeration under the target of energy saving and carbon reduction.In this work,landfill reclamation processes with forced aeration were simulated using aged refuses(ARs)of 1,4,7,10,and 13 disposal years,and the potential of field application was also investigated based on a field project,to identify the degradation rate of organic components,the O_(2)consumption efficiency and their correlations to microbes.It was found that the removal rate of organic matter declined from 20.3%(AR_(1))to 12.6%(AR_(13)),and that biodegradable matter(BDM)decreased from 5.2%to 2.4%at the set aeration rate of 0.12 L O_(2)/kg waste(Dry Matter,DM)/day.A linear relationship between the degradation rate constant(K)of BDM and disposal age(x)was established:K=−0.0002193x+0.0091(R^(2)=0.854),suggesting that BDM might be a suitable indicator to reflect the stabilization of ARs.The cellulose/lignin ratio decrease rate for AR1(18.3%)was much higher than that for AR13(3.1%),while the corresponding humic-acid/fulvic-acid ratio increased from 1.44 to 2.16.The dominant bacteria shifted from Corynebacterium(9.2%),Acinetobacter(6.6%),and Fermentimonas(6.5%),genes related to the decompose of biodegradable organics,to Stenotrophomonas(10.2%)and Clostridiales(3.7%),which were associated with humification.The aeration efficiencies of lab-scale tests were in the range of 5.4–11.8 g BDM/L O_(2)for ARs with disposal ages of 1–13 years,and in situ landfill reclamation,ARs with disposal ages of 10–18 years were around 1.9–8.8 g BDM/L O_(2),as the disposal age decreased.The increased discrepancy was observed in ARs at the lab-scale and field scale,indicating that the forced aeration rate should be adjusted based on ARs and the unit compartment combined,to reduce the operation cost. | Yihang Liu Chengqi Ning Qiujie Huang Zhaowen Cheng Weihua Cao Xianghui Wang Changfu Yang Hui Liu Jia Song Luochun Wang Ziyang Lou | 2023 | Waste Disposal and Sustainable Energy2023，5，3： | 0 |
