人工快速渗滤系统处理农村生活污水实验研究

Experimental study on artificial fast filtration system for treating rural sewage

文章研究了不同渗滤介质组成的人工土柱对生活污水的处理能力,结果表明河砂+斜发沸石+方解石滤料对COD、NH3-N都有较高去除率,水力负荷也较高。将该组合用于农村生活污水处理工程,出水水质可以达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A标准。

This research aimed at recognizing sewage processing capacity of artificial soil column composed of different filtration mediums. The result shows that the filter material composed of sand, clinoptilolite and calcite has higher removal rate and hydraulic loading to COD and NH3-N. This filter material combination is used for rural sewage treatment project, the effluent can achieve I level A standard of the urban sewage treat- ment plants standards for pollutants discharge.
