以木炭作为曝气生物滤池的填料,并与陶粒填料作对比,考察了其在不同水力负荷下对污水的处理效能.结果表明,改变水力负荷对两个反应器的出水COD影响不大,但对其脱氮除磷效果的影响较显著.木炭滤池对氨氮和TN的去除效果要好于陶粒滤池的,当水力负荷为4m~3/(m~3·d)时,两反应器的脱氮效果最佳,此时木炭和陶粒滤池的出水氨氮浓度分别为4.7、7.7mg/L(去除率分别为80%和65%).综合考虑木炭滤池对COD、NH_4~+-N、TN和TP的去除效果,确定其最佳水力负荷为4 m~3/(m~3·d).

Charcoal was adopted as filler in biological aerated filter and compared with ceramsite.The treatment efficiency of sewage under different hydraulic loading was investigated. The results show that change in hydraulic loading has little influence on removal of COD but has significant influence on nitrogen and phosphorus removal in both filters. The removal efficiency of ammonia nitrogen and TN in the charcoal filter is superior to that in ceramsite filter. When the hydraulic loading is 4 m~3/(m~3·d),the nitrogen removal efficiency is the best. Under this hydraulic loading, the ammonia nitrogen concentration in the effluent of charcoal filter and ceramsite filter is 4.7 mg/L and 7.7 mg/L with the removal rate of 80% and 65% respectively. By the comprehensive comparison of removal rates of COD, NH_4~+-N,TN and TP in the charcoal filter, the optimum hydraulic loading is 4 m~3/(m~3·d).
