The invention provides an integrated wastewater treatment device, a method and a system. On one hand, membrane separation and a Fenton reaction are integrated, free radicals formed by the Fenton reaction can oxidate organic matters, metal complexes and inorganic matters, simultaneous removal of a variety of contaminants can be achieved due to actions such as adsorption, complexation and coprecipitation of metal hydroxide flocs, due to these characteristics, irreversible contaminants penetrating through a filter membrane can be greatly reduced, and the probability of fouling of the filter membrane is lowered; the filter membrane is located in an accommodating chamber, disturbance resulting from a mixer can simultaneously enable ferric hydroxide flocs accumulated on the filter membrane to disturb continuously, zero-valent iron particles disturb on the surface of the filter membrane, a free radical oxidant produced in situ can exert an online membrane cleaning action, then, the burden ofthe filter membrane is further reduced, and the fouling of the filter membrane is further prevented; compared with a Fenton reaction and membrane separation non-integrated device, the phenomenon of fouling of the filter membrane is greatly alleviated; in addition, the integrated wastewater treatment device is not prone to fouling, so that the integrated wastewater treatment device can be applied to continuous wastewater treatment; and due to an integrated device, the process cost, manufacturing cost and occupied space can be further reduced.
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...
