The invention provides an ultrasond-coupled integrated waste water treatment device, method and system. On one hand, membrane separation and Fenton reaction are integrated, free radical formed by theFenton reaction can oxidize organic matters, metal complex and inorganic matters, various pollutants can be removed simultaneously through the action of adsorption, complexing and coprecipitation of metal hydroxide floc and the probability of filtering membrane dirt blockage is reduced; furthermore, the filtering membrane is in an accommodating cavity, ferric hydroxide flocs accumulated on the filtering membrane can be disturbed continuously through disturbance caused by a mixer, zero-valent iron particles are distributed on the surface of the filtering membrane, and the on-line film cleaningeffect can be achieved by combining with in-situ generated free radical oxidizing agent, so that the burden of the filtering membrane is further reduced, dirt blockage of the filtering membrane is further prevented, and the filtering membrane dirt blockage phenomenon is greatly reduced compared with a Fenton reaction and membrane separation non-integrated device; in addition, ultrasonic cavitation, pyrolysis and mechanical vibration effects can generate synergistic effect with Fenton reaction, and the device can be applied to continuous waste water treatment.
Description
technical field [0001] The present invention relates to the technical field of wastewater treatment, and more specifically, to an ultrasonically coupled 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 deficiencies, this application improves the wastewater treatment technology of Fenton reaction or Fenton-like reaction, and c...
