含氯代有机物废液预处理技术研究进展

Research Progress on Pretreatment Technology in Waste Liquid Containing Chlorinated Organic Compounds

对于化工行业产生的含氯代有机物废液,现有环保技术处理难度较大,存在设备腐蚀,产生酸性气体与二噁英等二次污染物等问题。为解决含氯代有机物废液的高效清洁处理,可先对其进行预处理脱氯,再进行后续无害化或资源化处置。介绍了含氯代有机物废液预处理脱氯技术的原理、特点、研究进展与适用情况,并提出了含氯代有机物废液预处理脱氯技术发展与应用前景。

It is difficult to treat chlorinated organic waste liquid produced by chemical industry with current environmental protection technology. There is equipment corrosion, acid gas, dioxin and other secondary pollutants. To treat this waste liquid efficiently and cleanly, the dechlorination by pretreatment is carried out firstly, then the harmless or resourceful treatment is carried out subsequently. The principle, characteristics, research progress on pretreatment and applicability were introduced, then the development and application prospect of dechlorination by pretreatment technology in waste liquid containing chlorinated organic compounds were put forward.
