摘　　要：采用混凝沉淀/曝气生物滤池一体式反应器对校园污水的再生回用处理进行了研究,考察了系统对SS、COD、NH3-N和TP的去除效果。结果表明:在混凝剂最佳投量为40 mg/L、沉淀池水力负荷为5 m3/(m2.h)的条件下,混凝沉淀对SS、COD和TP的平均去除率分别为67%、51.3%和73.3%;在COD和NH3-N的容积负荷分别为2.16 kgCOD/(m3.d)、1.07 kgNH3-N/(m3.d)的条件下,曝气生物滤池对SS、COD和NH3-N的平均去除率分别为95%、93%和94.5%。系统出水水质满足《城市污水再生利用城市杂用水水质》(GB/T18920—2002)标准的要求。The integrated reactor of coagulation and sedimentation/BAF was used for school wastewater reclamation and reuse treatment. The removal efficiencies of SS, COD, NH3 - N and TP by the integrated reactor were investigated. The results show that under the conditions of optimal coagulant dosage of 40 mg/L and hydraulic loading of 5 m^3/（ m^2 · h）, the average removal rates of SS, COD and TP by coagulation and sedimentation are 67%, 51.3% and 73.3% respectively. When the volumetric loadings are 2.16 kgCOD/（ m^3 · d） and 1.07 kgNH3 -N/（ m^3 · d）, the average removal rates of SS, COD and NH3 - N by BAF are 95 %, 93 % and 94.5 % respectively. The effluent quality meets the requirements of the Reuse of Urban Recycling Water-Water Quality Standard for Urban Miscellaneous Water Consumption （ GB/T 18920 - 2002）.
