SBR处理城市生活污水的试验研究

Bench-scale Studies on SBR Process to Treat Municipal Wastewater

通过序批式活性污泥法 ( SBR)工艺处理城市生活污水的试验 ,研究了不同操作方式对处理效果的影响并得出最佳运行参数。当采用最佳操作方式运行时 ,COD、TP、TN的去除率分别为 90 % ,90 % ,75 %以上 ,出水能达到国家一级排放标准。

Aseries of performance data of sequence batch reactor(SBR) for treating sewage were obtained by using a bench-scale experimental unit.The data showed the effect of varied operating patterns upon the pollutant removal,which led to the optimum operation parameters.The removal of pollutants of the sewage in terms of COD,TN and TP reached above 90%,90% and 75% respectively in conformity with class I of the national standard for wastewater discharge.
