The invention provides an integrated waste water treatment device, method and system. On the one hand, due to the fact that membrane separation and a Fenton reaction are integrated into a whole, a free radical formed through the Fenton reaction can oxidize organic matter, metal complexes and inorganic matter, and by means of adsorption, complexing, coprecipitation and other effects of metal hydroxide flocs, multiple contaminants can be removed simultaneously. Accordingly, irreversible contamination of a filter membrane can be greatly reduced, the probability of fouling of the filter membrane is lowered, and the membrane is located in a containing chamber so that disturbance brought by a mixer can make ferric hydroxide flocs accumulated on the filter membrane disturbed continuously simultaneously; zero-valent iron particles are disturbed on the surface of the filter membrane, by combining an in-situ generated free radical oxidant, the on-line membrane cleaning effect can be achieved, then the burden of the filter membrane is further reduced, filter membrane fouling is further stopped, and the filter membrane fouling phenomenon is greatly relived compared with a Fenton reaction and membrane separation non-integration device; in addition, due to the fact that fouling is not likely to occur, the device can be used for continuous waste water treatment, and the integrated device canfurther lower the process cost, the manufacturing cost and the occupied area.
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] The Fenton reaction reacts with ferrous ions (Fe 2+ ) as a catalyst, hydrogen peroxide (H 2 o 2 ) is a wastewater treatment method of chemical oxidation, which generates hydroxyl radicals through the reaction of ferrous ions and hydrogen peroxide, and the hydroxyl 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 Fenton reaction still has many deficiencies, and there is room for improvement. Contents of the invention [0003] In order to solve the above-mentioned deficiencies, the present application improves the wastewater treatment technology of Fenton reaction or Fenton-like reaction, and combine...
