摘要
在低碳源条件下,研究了接触氧化-强化混凝组合工艺处理城镇污水的运行结果。结果表明,当进水COD96～180mg·L-1、ρ(NH3-N)17～45mg·L-1、ρ(TP)2～6.5mg·L-1时,其去除率分别可达到70%、85%、90%,浊度去除率为95%,出水水质达到城镇污水处理厂污染物排放标准(GB18918-2002)一级排放A标准,出水可回用。GC-MS分析表明,接触氧化-强化混凝组合工艺具有很强的有机物去除能力。
The composite process of contact oxidation and enhanced coagulation treating municipal sewage was investigated on the condition of low carbon source. The results showed that when t he influence with COD is 96- 180 mg·L^-1, NH3-N is 17-45 mg·L^-1 and TP is 2-6.5 mg·L^-1, the total removal rate can be 70 %, 85 % and 90% respectively,the removal rate of turbidity can be reached 95%, the effluent will be quite enough to meet the requirement of level A, class 1 in the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918-2002）, the effluent could be reused. Analysis of GC-MS showed that the composite process of contact oxidation and enhanced coagulation had good removal ability on organic compounds.
