榆林市某污水处理厂设计实例

Design of a Sewage Treatment Plant in Yulin City

为解决榆林市某县未经处理的废水,新建的污水厂采用奥贝尔氧化沟+混合反应+沉淀+过滤工艺,处理后出水SS≤10 mg/L,BOD≤10 mg/L,COD≤50 mg/L,TN≤15 mg/L,TP≤0.5 mg/L,出水水质达到GB18918-2002《城镇污水处理厂污染物排放标准》一级A标准,实现了社会效益、经济效益与环境效益的统一。

In order to treat waste water from Yulin county,a new Orbal oxidation ditch wastewater treatment plant using mixed reaction precipitation filtration process was built.Running results show that in treated effluent,SS≤10 mg/L,BOD≤10 mg/L,COD≤50 mg/L,TN≤15 mg/L,TP≤0.5 mg/L;Effluent quality can meet GB18918-2002 'municipal wastewater treatment plant emission standards' Ⅰlevel A standard;good social,economic and environmental benefits has been gained.
