| 摘 要： | 重点研究了活化污泥法强化一级处理对城市污水中重金属离子的去除效果。以实际生活污水和Cd、Cu、Zn、Cr6+、Pb、Mn六种城市污水中常见的重金属离子配水,采用活化污泥法的正常工艺条件,发现这几种金属离子去除的难易顺序为:Cd>Pb>Cu>Zn>Mn>Cr6+。水中的重金属离子与有机物间存在竞争吸附作用,共存时双方的去除效果都有所下降,但对Cd、Pb来说,有机物的存在则可以提高其去除效果。

| Abstract: | The removal efficiency of heavy metal in city wastewater treated by activated sludge process was studied.The order of removal efficiency is: Cd>Pb>Cu>Zn>Mn> Cr6 .Removal efficiencies interrelate with the hydrate-radius of heavy metal and hydrolyzation.When heavy metal and organic matter coexist in wastewater,their removal efficiencies all drop.But if heavy metal is with small hydrate-radius and easily integrated with organic matter into steady compound,such as Cd and Pb,the existence of organic matter will improve the removal efficiency. |
