| 1 | Flocculating characteristic of activated sludge flocs:Interaction between Al^(3+) and extracellular polymeric substances显示文摘Aluminum flocculant can enhance the flocculating performance of activated sludge.However,the binding mechanism of aluminum ion(Al 3+) and extracellular polymeric substances(EPS) in activated sludge is unclear due to the complexity of EPS.In this work,threedimensional excitation emission matrix fluorescence spectroscopy(3DEEM),fluorescence quenching titration and Fourier transform infrared spectroscopy(FT-IR) were used to explore the binding behavior and mechanism between Al 3+ and EPS.The results showed that two fluorescence peaks of tyrosineand tryptophan-like substances were identified in the loosely bound-extracellular polymeric substances(LB-EPS),and three peaks of tyrosine-,tryptophanand humic-like substances were identified in the tightly boundextracellular polymeric substances(TB-EPS).It was found that these fluorescence peaks could be quenched with Al 3+ at the dosage of 3.0 mg/L,which demonstrated that strong interactions took place between the EPS and Al 3+.The conditional stability constants for Al 3+ and EPS were determined by the Stern-Volmer equation.As to the binding mechanism,the-OH,N-H,C=O,C-N groups and the sulfurand phosphorus-containing groups showed complexation action,although the groups in the LB-EPS and TB-EPS showed different behavior.The TB-EPS have stronger binding ability to Al 3+ than the LB-EPS,and TB-EPS play an important role in the interaction with Al 3+. | Xiaodong Ruan Lin Li Junxin Liu | 2013 | Journal of Environmental Sciences2013，25，5： | 6 |
| 2 | 畜禽粪便堆肥中重金属污染调控技术的研究现状显示文摘针对畜禽粪便堆肥中重金属污染现状、处理方法及研究现状作一概括,着重介绍了国内外重金属治理技术,解决畜禽粪便污染问题的思路和方法。应用木醋液对畜禽粪便的预堆制过程中重金属形态变化、钝化形式与效果的研究,将成为未来研究畜禽粪便堆肥中重金属治理的热点和趋势。 | 李治宇 张亚兰 刘飞 周岭 | 2013 | 新疆农机化2013，，5： | 3 |
| 3 | 水生蔬菜答农民问(46-2):蒲菜在环境改良中有什么应用价值?显示文摘多年来,笔者经常接到莲藕等水生蔬菜种植户的咨询,他们大多是农民,也有企业家。笔者也经常到全国各产区进行现场调研及技术咨询和讲座,到各级广播电台农业节目中进行咨询和讲座。在与种植户的交流中,接触到了大量从种植者角度提出来的问题。最近几年,更是通过电话、彩信、微信、QQ及电子邮件等方式,接触到大量从事莲藕等水生蔬菜种植的年轻人提出的问题。为此,笔者对种植者特别是青年种植者提出的部分问题进行整理,并力求进行较为全面的回答。 | 刘义满 魏玉翔 | 2021 | 长江蔬菜2021，，13： | 0 |
