用剩余活性污泥吸附Cu^2+和Zn^2+的初步研究
Study on Adsorption of Cu~(2+) and Zn~(2+) with Waste Activated Sludges
-
摘要: 城市污水厂在净化污水的同时,产生了大量的含高浓度重多金属离子(M^n+)等有害物的剩余活性污泥(WAS),如何有效地处置利用它已社会的广泛关注,将部分WAS作吸附剂回流至初沉池来降低污水及污泥中M^n+含量,是一个非常好的创新设想,该研究旨在作有关WAS的静态实验,发现其吸附规律和几个主要因子(pH,吸附时间,投配比等)的最佳值,结果表明活性污泥对Cu^2+和Zn^2+有很好的吸附效果。Abstract: Municipal sewage treatment plant produces a lot of waste activated sludge(WAS) containing high concentrations of metal-ion and other harmful material when it cleans sewage. How to dispose and utilize sludge has attracted wide concern. A valuable innovative suggestion is that some WAS be used as absorbent and retumed to the primary cldrifier to decrease the content of metal-ion in the sewage and sludge. This study aimed at doing some absorption experiment in the laboratory in order to elucidate adsorption patterns and the optimal values of factors involved. The result indicated that WAS exhibited potential for Cu2+ and Zn2+ adsorption.
