为使沈阳北部污水处理厂二级生化处理出水达到回用水水质，在中试规模（1 m3/h）下采用污泥回流高效絮凝+过滤工艺对其进行了深度处理。试验结果表明，经该工艺处理后，色度、浊度、CODCr、总磷平均去除率分别达到43%、90．6%、65．6%、86．3%，出水色度为19．7度，浊度为0．6 NTU，CODCr为25．3 mg/L，总磷为0．6 mg/L，出水色度、浊度、CODCr、总磷达到《城市污水再生利用工业用水水质》（GB/T 19923—2005）的要求。但系统对氨氮的去除率仅为19．7%，有待进一步提高。

In order to ensure the treated secondary effluent in sewage plants in the north of Shenyang to achieve the water quality of recycled water,the advanced treatment of the effluent has been accomplished by the highly efficient flocculation of sludge reflux+filtration process,under pilot scale (1 m3/h). The results show that after the treatment, the average removing rates of chroma,turbidity,CODCr,and TP,from effluent are 43%,90.6%,65.6%and 86.3%, respectively,the effluent chroma 19.7 degree,turbidity 0.6 NTU,CODCr 25.3 mg/L,and TP 0.6 mg/L. The chroma, turbidity,CODCr and TP of effluent meets the requirements specified in“the Reuse of Urban Recycling Water-Water Quality Standard for Industrial Uses”(GB/T 19923—2005). Nevertheless,since the removing rate of ammonia nitrogen is only 19.7%, further improvement is still needed.
