The invention provides an integrated treatment device, method and system for wastewater. According to the device, method and system provided by the invention, membrane separation and a persulfate advanced oxidation reaction are integrated together, free radicals formed by the persulfate advanced oxidation reaction can oxidize organic matter, metal complexes and inorganic matter, metal hydroxide flocs have the effects of adsorption, complexation and co-precipitation, so that simultaneous removal of a plurality of pollutants can be realized, and the features can greatly reduce irreversible pollution penetrating a filter membrane, thereby reducing probability of fouling and blocking of the filter membrane; the filter membrane is located in an accommodating chamber, disturbance brought by a mixer can simultaneously disturb iron hydroxide flocs accumulated on the filter membrane, zero-valent iron particles are disturbed on the surface of the filter membrane, an free radical oxidant generated in situ is combined, so that the on-line membrane cleaning effect can be realized, burden on the filter membrane is further reduced, the filter membrane is further prevented from being fouled and blocked, and the device provided by the invention greatly reduces fouling and blocking phenomena of the filter membrane compared with a persulfate advanced oxidation reaction and membrane separation non-integrated device; and the device, the method and the system can be used for continuous treatment of the wastewater.
Description
technical field [0001] The present invention relates to the technical field of wastewater treatment, and more specifically, to an integrated wastewater treatment device, method and system. Background technique [0002] Advanced persulfate oxidation uses transition metal ions as activators, and persulfate (S 2 o 8 2- ) is a wastewater treatment method for chemical oxidation, which generates sulfate radicals through the reaction of transition metal ions and persulfates, and sulfate radicals can destroy organic matter in wastewater or complexes of organic matter and heavy metals, thereby achieving the purpose of wastewater degradation . The current wastewater treatment technology based on persulfate advanced oxidation still has many deficiencies, and there is room for improvement. Contents of the invention [0003] In order to solve the above shortcomings, the present application improves the wastewater treatment technology of persulfate advanced oxidation reaction, and c...
