摘　　要：有机废水的处理一直受到关注,而废水中对氯苯酚这类污染物毒性大,化学性质稳定,必须对其进行处理。将超声技术引入到Fenton试剂氧化降解对氯苯酚中,通过实验分析影响对氯苯酚降解率的因素,如超声功率、溶液初始浓度,溶液初始pH值、Fe2+添加量、H2O2添加量等。研究结果表明:在100ml浓度为100mg/L的对氯苯酚模拟废水中加入0.15g的Fe2+和0.3ml H2O2,调节初始pH=3,超声输出功率为300W,反应时间为90min,此时降解效果最好,去除率为93.21%。The organic waste water treatment is deeply concerned by people all the time. 4-CP is a kind of contamination in waste wa- ter, which is highly toxic and chemically stable. It must be treated. This article introduces the ultrasound technology into in the degra- dation of 4 - chlorophenol （4-CP） by improving Fenton reagent, The major influencing factors such as the power of uhrasound, initial concentration, initial pH, the initial concentration of Fe2 ~ , the dosage of H2 02 are investigated. The resuhs shows that the largest re- moval of 4 - chlomphenol （4-CP） with initial concentration of 100mg/L could reach 93.21% under the optimal conditions ： adding O. 15g Fe2~ and 0.3ml H202 to the waste water of volume 100n-d, adjusting the initial pH to 3, and the ultrasound power being 3OOW, and the reaction continuing 90 rain. In this condition, the removal rate is 93.21%.
