摘　　要：通过单因素试验研究了生物絮凝吸附+生物接触氧化组合式一体化工艺对城市污水悬浮物SS、化学需氧量COD、氨氮NH3-N、总氮TN、总磷TP的去除效能和机理。试验结果表明:在组合工艺的较优运行条件下,装置对SS、COD、NH3-N、TN、TP的平均去除率分别为88.7%、89.3%、87.9%、73.4%、58.8%。组合工艺对污染物的总体去除效果良好,且稳定可靠,其中生物絮凝吸附段对总磷的去除率为32.4%,生物接触氧化段对总磷的去除率为39.1%。The removal efficiency and mechanism of sewage SS, COD, NH3 - N, TN, TP was studied through the single factor experiment of strength bio- flocculation ＋ bio- contact oxidation combined technics. The results showed that： under the optimum operating conditions of combination technics, the average removal rate of KS, COD, NH3 - N, TN, TP were 88.7%, 89.3%, 87.9 %, 73.4 % , 58.8 % respectively. The pollutant removal efficiency were good, stable and reliable. In which, the total phosphorus removal rate of bio- flocculation and adsorption was 32.4 %, the total phosphorus removal rate of bio - contact oxidation was 39.1%, the removal mechanism of phosphorus was discussed in this paper.
