摘要
设计生活污水与酸性矿山废水混合处理实验,重点考察混合水体水质变化特征及混合体系中污染物的分布,以研究生活污水与酸性矿山废水混合后,其对硫酸盐还原菌生长的影响,并对污染物的去除效果及机理进行分析。结果表明,化粪池水与酸性矿山废水混合后能去除水体中50%以上的Fe、Zn、Cu、Cd和Ni,提供充足的有机碳源等,这些可以为硫酸盐还原菌提供更适宜的生长环境。由于污染物间的吸附作用,仍有部分污染物不能沉降,以悬浮物形态存在于水体中。
The experiment was designed to combine domestic sewage and acid mine drainage. In order to study the effects of the mixed water on the growth of sulfate reducing bacteria,and analyze the removal effect and mechanism of pollutants,some indicators were investigated,including the characteristics of water quality and the distribution of pollutants. The results show that the septic tank water could remove more than 50% Fe,Zn,Cu,Cd and Ni in water,bring in more organic carbon and so on,this would provide a more suitable growth environment for sulfate reducing bacteria. Moreover,some of the pollutants could not be settled in the form of suspended matter in water due to the adsorption.
