High efficiency detoxifcation method and device of organic wastewater

Abstract

The invention relates to a high-efficiency detoxification method of organic waste water, and a device thereof. The method mainly comprises the following steps of: mixing, catalytic reaction, oxidant reduction and the like. Organic waste water to be treated is led to a pipeline mixer for sufficient mixing with H2O2 and O3, then enters a catalytic reactor composed of a catalytic reaction unit, the catalytic reaction is carried out under the action of catalysts which uses active carbons as carriers and under the inducement of ultraviolet light, and enters an oxidant reduction unit again; reducers are filled into the organic waste water, and after reduction reaction is carried out to the organic waste water, waste water which is in accordance with requirements is lead out. The device is composed of a pipeline mixer used for sufficient mixing for organic waste water, H2O2 and O3, wherein, the rear part of the pipeline mixer is connected with a catalytic reactor composed of a catalytic reaction unit; and the rear part of the catalytic reactor is connected with an oxidant reduction unit. The invention has the characteristics of simple technical allocation, low processing cost, simple operation control, good detoxification treatment effect and the like.

Description

technical field [0001] The invention relates to an efficient detoxification method and device for organic waste water, in particular to a novel high-efficiency detoxification method and device for difficult-to-biochemical organic waste water, which belongs to waste water treatment technology. Background technique [0002] Biodegradable organic wastewater treatment has always been a very popular technical focus of environmental protection professional engineers and technicians who are committed to the field of wastewater treatment, especially in some pharmaceuticals, pesticides, dyes, daily chemical manufacturing, landfills, leachation Liquid treatment and other industries, the production wastewater contains a lot of biodegradable, such as most halogen-containing compounds, ether compounds, nitro compounds, azo compounds, tertiary amines and quaternary ammonium salt compounds, S-containing organic compounds and some Heterocyclic organic compounds, etc., are difficult to handl...
