摘要
研究了氯苯废水的环己烷萃取工艺,以及采用不同吸附剂对废水处理结果的影响因素和规律,氯苯废水经环己烷萃取-粉煤灰吸附耦合技术处理能达到国家排放标准GB8978-1996。
The factors affecting the organic concentrations in water were studies.A technique to treat waste water in the processes is obtained.The waste water is extracted by cyclohexane to recover chlorobenzene.After extraction operation the waste water is treated by adsorption operation using pulverized coal ash as an absorbent.The waste water can meet the standard GB8978-1996.
