摘要
针对焦化废水及其出水的特点,采用碱式稀土混凝剂(ARC)对其进行混凝处理实验,并且测定了原水和处理后的水的化学需氧量(CODcr)、浊度、色度、pH等水质指标,同时进行了相关的结果对比分析。并通过与常用的焦化废水处理所用的用混凝剂聚合硫酸铁(PFS)、聚合氯化铝铁及现用混凝剂M180进行混凝试验对比可知,碱式稀土混凝剂(ARC)在浊度、CODcr、色度、pH等水质指标去除方面均好于其它三种混凝剂对焦化废水出水的处理效果。
Aiming at the characteristics of coking wastewater and the treated water, basic rare earth coagulant （ ARC ） was used to experiment on coking wastewater coagulation treatment. Chemical oxygen demand （CODcr） , turbidity, chroma, pH and other water quality indices of the raw water and the treated water were tested. The purified water obtained by using basic rare earth Coagulant has better indices such as CODcr, turbidity,chroma and pH than by using commonly used coagulant polyferric sulfate,poly aluminum ferric chloride and M180.
