摘要
炼油厂汽提废水含较高的酚和COD,会对污水处理场产生冲击。采用曝气生物滤池法对其进行处理,取得了满意的结果。当水力停留时间为2.0h,处理后出水的酚和COD平均浓度分别为8.5mg/l和140mg/l,平均降解率分别大于90%和70%,完全可以消除它们对污水处理场的冲击。
Wastewater produced from stripping tower, containing high strength phenol and COD, can bump against wastewater treatment facility. The satisfactory results have been obtained with biological aeration filter: Under the hydraulic retention time of 2. Oh, the average effluent concentration for phenol and COD is 8 .5mg/L and 140mg/L respectively, the average removal percentage for phenol and COD is more than 90 % and 70 % respectively, and overload to wastewater treatment plant can be thoroughly removed.
