摘要
江苏某化工厂在生产过程中排放出高浓度且含高盐分的氯苯废水,通过小试研究提出了蒸发—精馏—Fenton试剂—混凝—水解—接触氧化处理工艺。工程运行结果表明,COD、盐分和氯苯的平均去除率分别为99.5%、99.2%和99.9%,出水水质达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)三级标准,处理成本约为传统焚烧法的20%。
Chlorobenzene wastewater with high concentration and high salinity discharged from a chemical plant in Jiangsu has been studied by means of different technologies in small scale. The combined process evaporationrectification-Fenton reagent oxidation-coagulation-hydrolysis acidification-contact oxidation are brought forward. The running results show that the removal rates of COD, salinity, and chlorobenzene are 99.5%, 99.2% and 99.9%, respectively. The effluent water quality reaches the third class of Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918--2002）. The treatment cost account for 20% of the cost of incineration.
