Chlorine-containing organic waste gas purification treatment process

The invention provides a chlorine-containing organic waste gas purification treatment process, and belongs to the technical field of waste gas treatment. According to the specific method, chlorine-containing organic waste gas, such as high-concentration dichloromethane, dichloroethane, propionyl chloride, chlorobenzene and the like is collected; under the action of an induced draft fan, the chlorine-containing organic waste gas sequentially passes through an iron-carbon micro-electrolysis reactor and UV photolysis equipment for treatment; and finally, the waste gas is subjected to up-to-standard discharge through an exhaust funnel. The chlorine-containing organic waste gas is pretreated by utilizing the iron-carbon micro-electrolysis, so that the concentration of the chlorine-containing organic waste gas can be reduced to the greatest extent; and meanwhile, the macromolecular substances can be oxidized and cracked, the treatment efficiency of the UV photolysis is improved, and therefore the up-to-standard dis
