摘要:

采用硅藻土与混凝剂复配对生活污水进行处理。结果表明:三种复配剂在最佳工艺条件下对CODCr的去除率在64.0%以上,SS的去除率在88.9%以上,氨氮的去除率在41.0%以上,较单独使用混凝剂的效果要好,出水达到国家城镇污水处理厂污染物排放标准(GB18918—2002)二级排放标准。运行费用低于同类处理工艺,具有良好的推广应用前景。

Abstract:

Treatment of town domestic sewage with the compounds of diatomite and coagulants(CDGC) is investigated. The results show that three types of CDGC in the optimal operating conditions have better effect on domestic sewage treatment than coagulants alone. The CODCr removal rate is above 64.0%, SS and NH3-N removals are above 88.9% and 41.0%, respectively. The effluent water quality reaches the second grade discharge standard of GB 18918-2002. The running cost is lower than other general treatment technics. Therefore, it has a wider application potential.

Key words: domestic sewage, diatomite, enhanced coagulation
