SBR工艺运行方式改变处理校园生活污水的试验研究

通过改变SBR工艺的运行方式,考察不同运行条件下校园生活污水中CODCr,NH3-N,TP的去除率,从中确定最佳运行参数;进水搅拌时间45min,进气量0.5m3/h,曝气时间5h,停曝搅拌时间75min,沉淀时间75min。实现CODCr高去除率的同时达到脱氮除磷的目的,并且氮和磷的去除率稳定在70%和35%左右。

The removal efficiency of CODCr, NH3-N were investigated by changing the operating mode and TP on campus sewage under different operating conditions of SBR process, from which to determine the optimum operating parameters;the water stirring time is of 45 min, the intake air amount is of 0.5 m3/h, aeration time is 5 h, stop aeration and agitation time is 75 min, removal was achieved while realizing settling time is 75 min. The purpose of denitrification and phosphorus high CODCr removal rate, the removal rate of nitrogen and phosphorus was stabilized at around 70% and 35% separately.
