摘　　要：高浓度活性污泥法采用兼氧、好氧组合流程,最显著的特点是全流程活性污泥浓度高和好氧前段的溶解氧浓度低。显著的同步硝化反硝化使该工艺可以在相当短的水力停留时间和较低的总回流比条件下,达到极高的总氮去除效果,同时相当有效地去除总磷和其他污染物。在原中试结束一年后又开展了后续试验,不仅重现了当时高浓度活性污泥法的优异处理效果,而且其脱氮除磷效果进一步提高。High-concentration activated sludge process integrates facultative anaerobic and aerobic stages, and it is characterized by high MLSS in whole process and low DO in aerobic forepart. This process can excellently remove TN at short HRT and small TRR by significant SNI）, and efficiently remove TP and other pollutants. The subsequent test after one year from the original pilot test show that this process still has the excellent treatment efficiency, and the nitrogen and phosphorus removal efficiency is further improved.
