摘要
针对当前农村生活污水治理的热点,研究中试规模试验条件下应用自主呼吸生态滤池技术处理农村生活污水的效果。试验结果表明:自主呼吸生态滤池技术对COD、TN、NH_(3)-N、TP和SS都有较好的去除效果,平均去除率分别为(79.22±4.28)%、(66.13±6.58)%、(84.25±4.87)%、(94.23±0.67)%、(89.07±1.35)%。主要污染物指标均能稳定达到GB 18918—2002《城镇污水处理厂污染物排放标准》一级A标准。采用填料分层填装、自主呼吸系统、间歇式运行方式等工艺设计,互相耦合,有效提高了系统的处理效果。
In view of the current hot spots of rural domestic sewage treatment,the effect of applying autonomous breathing ecological filter technology to treat rural domestic sewage under pilot scale test conditions was studied. The results showed that the technology had a good removal effect on COD,TN,NH3-N,TP and SS,and their average removal rates were( 79. 22±4. 28) %,( 66. 13±6. 58) %,( 84. 25±4. 87) %,( 94. 23±0. 67) % and( 89. 07±1. 35) %,respectively. The main indicators could stably reach the class A standard of Discharge Standard of Pollutants for Urban Sewage Treatment Plants( GB 18918—2002). The process design of layered packing,autonomous breathing system and intermittent operation mode were coupled with each other,and eventualy improve the treatment effect of the system.
