摘　　要：采用复合多级生物反应器+接触沉淀-BAF工艺进行城市污水再生回用处理,试验结果显示,在常温条件下,当进水平均浓度CODcr=326 mg/L、BOD5=241 mg/L、NH3-N=36 mg/L、SS=243 mg/L、TN=62 mg/L时,系统出水水质为CODcr=15.3 mg/L、BOD5=8.8 mg/L、NH3-N=4.7 mg/L、SS=15.5 mg/L、TN=13.9 mg/L、浊度7.6NTU,出水水质达到了城市杂用水水质标准(GBT18921-2002)的要求.Experimental study is made on the recycle of urban waste water to use the Compound Multi-grade Biological Reactor and Contacted Sedimentation- BAF technique. The result shows that on the condition of common temperature, as the average input water density is CODcr = 326 mg/L,BOD5 = 241 mg/L,NH3 - N= 36 mg/L,KS = 243 mg/L,TN = 62 mg/L, the system output water quality can get to CODcr = 15.3 mg/L, BOD5 = 8.8 m g/L, NH3 - N = 4.7 mg/L, KS = 15.5 rag/L, TN = 13.9 mg/L, the turbidity is 7.6NTU, therefore the outflow water quality can get the standards specified in Urban Miscellaneous Use Standard （GB/T18921 -2002）.
