摘要
将平板膜组件与传统脱氮除磷工艺相结合,构建了膜生物反应器强化生物脱氮除磷中试系统,并用于处理城镇污水处理厂的污泥系统废水。结果表明,出水CODCr、BOD5、NH3—N、TN和TP的平均浓度分别为70.8 mg/L、8.7 mg/L、15.1 mg/L、29.7 mg/L和0.38 mg/L,达到或接近了《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级标准。
By combining the plate membrane bioreactor with the conventional biological nitrogen and phosphorus removal process, a pilot test system for enhaneing biological nitrogen and phosphorus removal of membrane bioreactor (MBR) was constructed and used to treat sludge water from municipal wastewater treatment plant. The results show that the effluent average concentrations of CODCr, BODs, NH3-N, TN and TP are 70. 8 mg/L, 8. 7mg/L, 15. 1mg/L, 29. 7 mg/L and 0. 38 mg/L respectively. Therefore, first stage criteria specified in the "Discharge standard of pollutants for municipal wastewater treatment plant (GB 18918 2002)" is achieved or approached.
