熄焦粉吸附处理焦化厂生化废水的试验研究

Research on Absorption Disposal of Biochemical Effluent with Extinguishing Coke Powder in the Coke-oven Plant

针对目前焦化厂生化脱酚废水的化学需氧量（ＣＯＤ值）普遍超标现象，采用焦化厂自产的熄焦粉给予吸附处理，使焦化厂生化废水的化学需氧量达到国家一级排放标准，在某种程度上可以取代废水的三级处理，即取代废水的深度处理．

The paper offers the research into the present condition that chemical oxygen demand in discarding-phenol effluent of the coke-oven plant commonly goes beyond the state-set limit absorption disposal is achieved by introducing extinguishing coke powder made in the coke-oven plants. This practice serves to make COD in the cokary biochemical effluent stand up to the state-set emission standard. To some extents, the absorption disposal is able to replace the three-grade disposal of waste water, that is, the further disposal of waste water.
