MSBR和滤布滤池组合工艺在中水回用中的应用

Removal Effect of Suspended Substance and Phosphorus by Combined Process of MSBR and Aqua Cloth Media Filtration

采用MSBR和滤布滤池的组合工艺处理污水,结果表明:该组合系统运行稳定,对污染物的去除效果明显,平均出水COD34.9 mg/L、BOD5 5.2 mg/L、SS 3.8 mg/L、NH4+-N 0.8 mg/L、TN 13.8 mg/L、TP 0.4 mg/L,完全满足《城市污水再生利用城市杂用水水质》(GB/T18920-2002)的要求。出水用于绿化浇灌、道路冲刷、药剂稀释等方面,取得了良好的社会效益和经济效益。

The combined process of MSBR and aqua cloth media filtration was used to treat sewage.Results showed that the system treatment was stable,and contaminant removal effect was obvious,with average effluent of COD,BOD5,SS,NH4＋-N,TN and TP as 34.9 mg/L,5.2 mg/L,3.8 mg/L,0.8 mg/L,13.8 mg/L and 0.4 mg/L respectively,which can meet the requirement of Reuse of Urban Recycling Water-Water Quality Standard for Urban Miscellaneous Water Consumption of GB/T18920-2002.The effluent was used to greening,road washing and chemical dilution,with cost effective effect.
