摘　　要：在突发事故中泄漏在水体中的丙烯腈污染物对环境危害非常大,具有排放浓度高、生物毒性大的特点,该废水用常规的生物处理技术难以凑效实验室采用Fenton氧化法处理水中不同浓度丙烯腈污染物,丙烯腈去除率可达90%以上;对氧化后水样利用二氯甲烷进行酸、碱条件萃取,经K-D浓缩器浓缩200倍后采用GT-MSS定性分析得知:丙烯腈污染物经Fenton试剂氧化后,转化产物以二氧化碳和水为主,微量为含氯化合物。In sudden accidents,aerylonitrde contamination in water is very harmful to the environment.It has the characteristic's of high concentration and high biological toxicity.It's hard to treat such wastewater with conventional biological treatment technology.Fenton oxidation process is adopted in laboratory for the treatment of water with different concentrations of acrylonitrile pollutants and acrylonitrile removal rate can reach more than 90%;acid-base extraction is carried out for the oxidation sample by using methylene chloride and after concentrating 200 fold through the K-D concentrator,GT-MSS qualitative analysis is adopted.And the results indicate that after Kenton reagent oxidation for the acrylonitrile pollutants,the conversion products are mainly carbon dioxide and water with trace nitrogen compounds.The wastewater after oxidation treatment will not bring secondary pollution problems.
