太原市某污水处理厂各工段重金属含量分析

Analysis on Heavy Metal Content in Each Processing Section of A Sewage Treatment Plant in Taiyuan

以太原市某污水处理厂的实际工艺为例,采集各工段污水、污泥为样,对传统活性污泥法水处理工艺运行中的镍、镉、锌、铜的质量浓度进行了分析,结果表明,部分活性污泥回流到初沉池后发现部分重金属在沉淀池中的去除率较高。

This paper took an actual sewage treatment plant as example,selected sewage and sludge samples in each processing section to study traditional activated sludge system.In the process,it analyzed the molar content of the heavy metals including nickel、cadmium、zinc、copper.The results showed that removal rates of heavy metals in return sludge in primary clarifier are higher.
