SBR法处理城镇生活污水工艺设计

面对随着我国社会发展进步而日益严重的生活污水污染以及我国中小城市越来越迫切需要建成污水处理厂的问题,设计通过对现行的活性污泥的各种工艺的比较,结合中小城市的特点,活性污泥法中的SBR工艺进行设计处理。设计目标是出水水质达到我国《城镇污水处理厂污染物排放标准》（GB 1819-2002）一级B类排放标准：p H=6~9;BOD5≤20mg/L;COD≤60mg/L;SS≤20mg/L;NH3-N≤8mg/L;TP≤1mg/L。

Along with our country＇s social development progresses, the sanitary sewage pollution becomes more and more serious day by day. And the Sewage treatment plants are urgently needed to be built in small and medium-sized towns and cities in our country. Facing with the two problems, the author finally chooses the SBR craft in the active sludge to carry on the design processing through choosing each craft in the present cireulation＇s active sludge and combining the characteristics of small and medium-sized towns and cities. The final objective of this project is to let the quality of leakage water reach the ＂Pollutant Discharge Standard of Cities＇ Sewage Treatment Plants＂ （GB 1819-2002） the first-level B kind of emission standard： pH=6-9; BOD5≤ 20mg/L; COD ≤60mg/L; SS ≤ 20mg/L; NH3-N ≤ 15mg/L; Tp≤1 mg/L
