摘要
通过单因素试验研究了强化生物絮凝＋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％，并对装置的除磷效果进行了分析。
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 SS, 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%, and discussed the removal effectiveness of phosphorus.
