利用粉煤灰处理含碱污水的试验研究

为了探讨火电厂除灰水中的粉煤灰（含炉渣）对炼油厂含碱污水中石油类、ＣＯＤ(ｃｒ)等污染物的吸附处理效果，根据某单位现场情况，将炼油厂含碱污水送入火电厂除灰沟→经充分混合排入储灰场→并经长时间沉降分离的流程进行模拟试验，结果表明：由于粉煤灰的吸附作用，显著降低了炼油厂含碱污水中的石油类、ＣＯＤ(ｃｒ)、挥发酚、碳化匕物等污染物。

The Experimental Study on the Treatment of Alkaline Wastewater by Coke Breeze

In order to study the absorption effect of coke breeze (with content of pen-breeze)for the pollutants such as oils and CODcr, the experiment drained off the alkaline wastewater ofrefinery into coke breeze channel of thermal power station according to the refinery's site situation.They are fully mixed and discharged into the storage field of coke breeze. Simulated experiment isconducted using the process of long time of sedimentation and separation. The results shows: due tothe absorption of coke breeze, pollutants in the alkaline wastewater such as oils, CODcr, volatilephenols and sulfide, are remarkably reduced.
