预处理焦粉对焦化厂生化废水的吸附处理试验

Adsorption Treatment of Coking Effluent by Preprocessed Coke Powder

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经活化或酸化处理后吸附处理焦化厂生化废水 ,使焦化厂生化废水的化学需氧量达到了国家一级排放标准。该方法在某种程度上可以取代废水的三级处理 ,有着潜在的巨大的社会效益和经济效益。

At present,the chemical oxygen demand(COD) in dephenolizing effluent of coking plant generally exceeds national standard.A new method for disposal of coking plant effluent by activivated(or acidified) extinguishing coke power obtained from this plant was developed.Test results show that after adsorption treatment,the COD in the coking plant biochemical effluent can reach discharging standard.To some extent,this disposal method can replace the waste water three grade disposal.
