摘　　要：针对沈阳北部污水处理厂二级出水回用处理进行中试规模的试验研究,试验结果表明:曝气生物滤池(BAF)+高效混凝沉淀池组合工艺能全面净化原水的水质,在气水比3∶1,水力负荷为1.25 m3/m2.h条件下,对氨氮、CODC r的平均去除率分别达到92.35%,41%;对SS和Tp的去除率分别达到89.82%,42.74%。Pilot - scale experiment for advanced treatment of secondary effluent from Shenyang Northern Wastewater Treatment Plant for reusing was conducted. The result showed that the source water quality can be greatly improved by the combination process of biological aerated filter（BAF） and high -performance coagulation- sedimentation. The average removal rate of HN3 - N, CODcr, SS and Tp were 92.35 %, 41%, 89.82 % and 42.74 % respectively with gas/water ratio 3 to 1 and hydraulic loading 1.25 m^3/m^2 · h.
