摘要
成都市三瓦窑污水处理厂一期设计规模10万 m^3/d,远期规模40万 m^3/d,采用鼓风曝气活性污泥法二级生化处理工艺。在进厂水质 BOD_5=200mg/L,SS=260mg/L条件下,出厂水质可望达到 BOD_5≤20mg/L,SS≤30mg/L。为降低能耗,减少基建投资和便于运行管理,本工程还采用了钟氏沉砂池、微孔曝气器、周边进水周边出水二沉池、污泥气浮浓缩池等新技术。
The designed capacity of Sanwayao sewage treatment plant is 10,000m^3/d in the first period,and that of the following period is 40,000m^3/d.It adopts activated sludge process with blower aeration.Under conditions of inffluent BOD_5=200mg/L,SS=260mg/L,those of the effluent can be reduced to below 20 mg/L and 30mg/L respectively.This project also introduces some new technologies to lower power consumption and construction cost.
