膜生物反应器A／O工艺处理生活污水试验

Experiment of Integrative A/O Membrane Bioreactor for Domestic Wastewater Treatment

试验采用A／O工艺和膜生物反应器相结合对学校内生活小区污水的处理效果进行了中试研究。结果表明,该工艺对污染物有很好的去除效果,出水COD、NH3-N、TP分别为16mg／L、8．7 mg/L、1．78 mg/L,其去除率分别达到96％、83％、62％,出水水质均优于《城镇污水处理厂污染物排放标准》(GB18918-2002)中一级标准B标准。

The treatment effect on domestic wastewater in the biotope of school with Membrane bioreactor and A/O process was studied in pilot - scale test. The results show that this process can efficiently remove pollutants; the effluent COD, NH3 -N and TP is 16mg/L, 8.7 mg/L and 1.78 mg/L respectively, and the removal rate reaches 96% , 83% and 62% respeclively. The effluent quality exceeds B - class criteria specified in Discharge Standard of Pollutants from Municipal Wastewater Treatment Plant （ GB18918 - 2002）.
