浅析二氯甲烷废气净化处理技术

Analysis on the purification technology of dichloromethane waste gas

介绍了二氯甲烷的用途和近年排放情况,从富集回收和销毁降解两个角度详细综述了冷凝法、吸附法、吸收法、燃烧法、催化脱氯加氢法、光催化分解法等多种典型技术的原理、适用性及研究现状。最后总结了回收和降解两种手段的优缺点,展望了组合工艺在未来工业二氯甲烷废气处理的前景。

The application and emission of dichloromethane in recent years were introduced.The principle,applicability and research status of condensation method,adsorption method,absorption method,combustion method,catalytic dechlorination hydrogenation method and photocatalytic decomposition method were reviewed in detail from two aspects of enrichment recovery and destruction degradation.Finally,summed up the recovery and degradation of the advantages and disadvantages of two kinds of means,outlooked the prospects of combination process in the future industrial dichloromethane waste gas treatment.
