摘　　要：石油工业废水氯苯类有机物处理不当会对生态环境造成污染,为提高石油工业废水氯苯类有机物的处理效果,提出了基于自由基反应的石油工业废水氯苯类有机物的处理方法。在统计实验试剂和仪器设备的基础上,通过配置实验所需的溶液,测定石油工业废水氯苯类有机物的浓度。结果表明,降低石油工业废水氯苯类有机物的初始浓度、增大钴离子浓度和PMS的浓度,均能加快石油工业废水氯苯类有机物的处理速率,SO_(4)^(2-)·自由基的产生会导致氯苯类有机物的氯原子脱除形成Cl^(-),被SO_(4)^(2-)·自由基氧化后活性物种参与到石油工业废水氯苯类有机物的处理,提升氯苯类有机物的去除效果。Improper treatment of chlorobenzene organic compounds in petroleum industry wastewater will cause pollution to the ecological environment.In order to improve the treatment effect of chlorobenzene organic compounds in petroleum industry wastewater,the treatment of chlorobenzene organic compounds in petroleum industry wastewater based on free radical reaction was proposed.On the basis of statistical experimental reagents and instruments and equipment,the concentration of chlorobenzene organics in the wastewater of the petroleum industry is determined by configuring the solutions required for the experiment.The results showed that reducing the initial concentration of chlorobenzene organic compounds in petroleum industry wastewater,increasing the concentration of cobalt ion and PMS can accelerate the treatment rate of chlorobenzene organic compounds in petroleum industry wastewater.The generation of sulfate radical will lead to the chlorine atom removal of chlorobenzene organic matter to form chloride ion,which will be oxidized by sulfate radical to participate in chlorobenzene in petroleum industry wastewater The removal efficiency of chlorobenzene organics was improved by the treatment of organic compounds like chlorobenzene.
