| 1 | Dynamic membrane bioreactor performance enhancement by powdered activated carbon addition:Evaluation of sludge morphological,aggregative and microbial properties显示文摘The effects of powdered activated carbon(PAC) addition on sludge morphological, aggregative and microbial properties in a dynamic membrane bioreactor(DMBR) were investigated to explore the enhancement mechanism of pollutants removal and filtration performance. Sludge properties were analyzed through various analytical measurements. The results showed that the improved sludge aggregation ability and the evolution of microbial communities affected sludge morphology in PAC-DMBR, as evidenced by the formation of large, regularly shaped and strengthened sludge flocs. The modifications of sludge characteristics promoted the formation process and filtration flux of the dynamic membrane(DM) layer. Additionally, PAC addition did not exert very significant influence on the propagation of eukaryotes(protists and metazoans)and microbial metabolic activity. High-throughput pyrosequencing results indicated that adding PAC improved the bacterial diversity in activated sludge, as PAC addition brought about additional microenvironment in the form of biological PAC(BPAC), which promoted the enrichment of Acinetobacter(13.9%), Comamonas(2.9%), Flavobacterium(0.31%) and Pseudomonas(0.62%), all contributing to sludge flocs formation and several(such as Acinetobacter) capable of biodegrading relatively complex organics. Therefore, PAC addition could favorably modify sludge properties from various aspects and thus enhance the DMBR performance. | Zhenzhen Yu Yisong Hu Mawuli Dzakpasu Xiaochang C.Wang Huu Hao Ngo | 2019 | Journal of Environmental Sciences2019，31，1： | 9 |
| 2 | 太湖上游城市宜兴城区主干道路径流污染特征解析显示文摘通过监测2015年8月—2016年9月7场典型降雨事件,系统分析太湖上游城市宜兴城区3个不同功能区(环科园、新城区和老城区)主干道路径流污染特征.研究表明:宜兴市城区主干道路径流浊度、COD、TN、NH_3-N、TP浓度分别为(77.2±66.9)NTU、(97.2±79.7)、(3.0±1.9)、(0.93±0.59)和(0.35±0.36)mg·L^(-1).COD和TN超出地表水环境Ⅴ类标准,是该地区径流特征污染物.降雨过程中污染物浓度整体呈下降趋势,伴随有不同程度的波动,主要受地表残留污染物及降雨强度的影响.3个区域TN浓度差异不大,且主要以溶解态存在(>60%);环科园、新城区TP浓度差异不大,且主要以颗粒态存在(>70%);然而,受居民生活活动的影响,老城区TP主要以溶解态存在(>60%).此外,受交通及道路坡度影响,新城区道路径流浊度和COD污染最为严重.不同降雨事件径流污染物浓度变化较大,主要受干期长度和降雨强度的影响.干期长度越长、降雨强度越小,污染物累积量及可冲刷量越大.因此,加强控制宜兴市道路初期径流、路面颗粒物、径流颗粒物和TN以及老城区TP,对保护径流主要受纳水体南溪水系及太湖水体具有重要意义. | 丁庆玲 王倩 张琼华 王晓昌 Mawuli Dzakpasu | 2017 | 环境科学学报2017，37，9： | 8 |
| 3 | 人工湿地净化污水处理厂低浓度尾水的效果显示文摘文章构建一种以双向横流过滤单元为核心的人工湿地系统,以实际污水处理厂尾水为进水,研究了尾水湿地系统净化效果,发现采用该湿地模式的出水能稳定提升1个等级。为了进一步探究湿地系统除污机理,以污水处理厂实际低浓度尾水为进水,研究了该湿地系统不同植物单元污染物去除功效,讨论了植物、基质与微生物的协同作用机制。研究结果表明:(1)在不同植物的去污效果对比实验中,花叶芦竹植物单元对COD、TN、NH_(4)^(+)-N和TP的平均去除率最高,分别为20.11%、17.17%、28.08%和18.12%;(2)不同运行阶段时基质进出水端主要微生物群落差异较小;(3)系统反向进水时,湿地系统TN去除率可提升50.00%。研究结果对于尾水湿地建设具有一定指导意义。 | 李青 张琼华 周卫东 朱瑞亭 DZAKPASU Mawuli 熊家晴 王晓昌 | 2022 | 水生生物学报2022，46，10： | 4 |
| 4 | 污染物负荷对水平流人工湿地净化效果的影响机制显示文摘为了提高水平流人工湿地在乡村污水处理中的适用性,通过小试实验系统研究了污染物负荷与人工湿地污水净化效率间的关系。结果表明:人工湿地对污水中TP、COD和NH4^+-N的单位去除量能够随着进水负荷的增加而呈线性增加,对TN的去除则未呈线性增加。通过冗余分析,得出人工湿地对TN的去除率与进水NH4^+-N负荷、NO3^--N负荷、TN负荷呈负相关,与C/N呈正相关;对TN的单位去除量与进水NH4+-N负荷、NO3^--N负荷和TN负荷呈正相关,而与TP负荷和C/N呈负相关。 | 杨世博 郑于聪 Mawuli Dzakpasu 王晓昌 王文东 | 2020 | 工业水处理2020，40，6： | 3 |

| 13 | 竹基生物炭湿地基质对双酚A和磺胺甲恶唑的吸附特性研究显示文摘以竹子为原料通过高温热解方法制备了竹基生物炭基质,并用于水中双酚A(BPA)和磺胺甲恶唑(SMX)的吸附。通过比表面积和孔径分析、扫描电子显微镜、傅里叶红外光谱仪对竹基生物炭进行表征分析。结果表明:竹基生物炭吸附BPA和SMX符合伪二级动力学和Freundlich等温吸附模型,表明吸附机制是化学吸附过程,属于多分子层吸附。随溶液pH增加,竹基生物炭对SMX吸附量先增加后减小,pH=5时出现最高吸附去除率40.1%;然而,竹基生物炭对BPA吸附量溶液pH增加呈现逐渐减小趋势。水中共存腐殖酸对SMX的吸附有明显抑制作用,但腐殖酸和BPA通过氢键作用和π-π作用有力结合进而整体上促进了生物炭对BPA的吸附。 | 张恒峰 Mawuli Dzakpasu 王晓昌 郑于聪 | 2023 | 水处理技术2023，49，4： | 1 |
