BAF与EMBAF工艺处理校园生活污水的对比研究

Comparative Study on Campus Wastewater Disposal Using BAF and EMBAF

在同等工况条件下对比研究了曝气生物滤池(BAF)和生物菌剂强化曝气生物滤池(EMBAF)两种工艺对校园生活污水主要指标的处理效果.结果表明:EMBAF对校园生活污水中化学需氧量(COD)、氨氮(NH+4-N)的平均去除率达到90.7%和81.6%,较BAF分别提高13.4%、15.7%,并能稳定出水中磷(TP)的总含量.

In order to investigate disposal efficiency of campus wastewater by using biological aerated filters （ BAF） and effective microorganism biological aerated filters （ EMBAF） processes, two parallelled operated BAF processes are carried out under the same operating conditions.The results show that：the average removal rate of EMBAF for chemical oxygen demand（ COD） and ammonia （ NH4＋-N） can reach 90.7%and 81.6%, increasing by 13.4%and 15.7%than BAF’s.Compared to BAF, EMBAF can stabilize the total phosphorus （TP） of the effluent.
