摘要
采用地下渗滤系统处理滇池流域的村镇生活污水,进行了工程的设计和建设。工程设计处理水量为30 m3/d,设计水力负荷为0.08 m3/(m2·d)。该工程对COD,总氮,总磷的去除率分别可以达到86.7％,85.5％和96.5％。工程的基建投资和运行费用不高,管理简单,兼具有美化景观的作用,并可产生一定的经济效益。
Subsurface infiltration system has been designed to treat rural domestic wastewater in Dianchi valley. The treatment ability is 30 m3 /d and the design hydraulic loading of the infiltration system is 0.08 m3/(m2·d). The COD, total nitrogen and total phosphorus removal rates of the system reach 86. 7%, 85. 5% and 96. 5% respectively. The system offers advantages including lower construction and operation costs, easy maintenance and many economic returns.
