摘　　要：通过小试研究了城市污水生物絮凝吸附强化一级处理工艺去除污染物的效能和机理.试验结果表明：在较低的溶解氧浓度（DO=0.1～0.5 mg/L）下,该工艺对SS、COD的去除效果较好;在DO=0.2 mg/L、生物絮凝反应区的水力停留时间为2.16 h下,反应区内发生了同步硝化反硝化（SND）,脱氮效果较好,对NH3-N的平均去除率为87.5%.该工艺在去除城市污水中的有机物和氮污染物方面具有一定的优越性.An experiment on municipal wastewater treatment by biologically enhanced primary process was carried out. Under the low oxygen level of DO = 0.1 - 0.5 mg/L in the aeration zone, SS and COD can be removed effectively. With the HRT of 2.16 h in the aeration zone, Simultaneous Nitrification and Denitrification （SND） occurrs, which brings good nitrogen removal with average NH3 -N removal of 87.5 %. The process, being energy saving, can be used in municipal wastewater treatment with positive effects on organic matter and nitrogen removal.
