为了实现小区生活污水中水回用,采用生物活性炭对模拟小区生活污水进行处理。通过研究挂膜阶段和稳定运行阶段出水的COD、NH3-N、PO34-、pH等指标来考察生物活性炭对污水的处理效果。实验结果表明：系统运行16 d后,生物膜基本成熟,对COD及氨氮的去除率在75%以。稳定运行阶段,该系统对COD、NH3-N、PO34-的去除率均达到80%以上,出水COD、NH3-N及PO34-的浓度分别稳定在50 mg/L、1 mg/L及4 mg/L以下,出水水质符合《城市污水再生利用城市杂用水水质》（GB/T 18920-2002）中的排放标准。

In order to reuse community sewage,domestic sewage was treated by biological activated carbon to meet the water quality standards of the sewage reuse.The effects of operational conditions on the treatment were studied during the formation and stability of biomembrane.The CODCr,NH3-N and PO3-4 of the effluent were used as indicators.The experimental results showed that biomembrane grew and became stable when the system ran for 16 d.During the stable operation,the removal rate of CODCr,NH3-N and PO3-4 were more than 80%.Then CODCr,NH3-N and PO3-4 were 50 mg/L,1 mg/L and 4 mg/L,respectively,which complied with the water quality standards in city greening provided by Reuse of Recycling Water for Urban Water Quality Standard for Urban Miscellaneous Water Consumption(GB/T 18920-2002).
