中小型污水处理厂扩容升级改造路线探讨

Small and medium-sized sewage treatment plant capacity upgrade route

中小污水处理厂现状出水水质通常达不到国家一级A标准,针对这类污水厂的升级改造工程,总结了其设计原则和技术难点,并着重阐述了生物池改造方案和深度处理方案。

The effluent quality of small and medium-sized sewage treatment plants(STP)usually couldn,t meet the A-class standard in our country.This paper,for the expansion of these STPs upgrades,summarized the designing principles,difficulties and focuses.In addition,the biotank reconstruction program and the depth treatment were elaborated intensively here.
