Abstract

The invention provides an ultrasonic coupling integrated treatment device, method and system for wastewater. Membrane separation and a persulfate advanced oxidation reaction are integrated, free radicals obtained by the persulfate advanced oxidation reaction degrade organic matter, and destroy heavy metal complexes, organic arsenic and organic phosphorus, removal of multiple pollutants is realizedthrough metal ion floc due to adsorption, complexation and co-precipitation, so that the probability of filter membrane fouling is reduced; the filter membrane is located in an accommodation cavity,disturbance caused by a mixer can simultaneously disturb ferric hydroxide floc accumulated on the filter membrane constantly, zero-valent iron particles are disturbed on the surface of the filter membrane, a free radical oxidant generated in situ can play an on-line membrane cleaning effect, so that the burden on the filter membrane can be further reduced, and the filter membrane can be further prevented from being blocked due to pollutants; and compared with a persulfate advanced oxidation reaction and membrane separation non-integrated device, the device provided by the invention greatly reduces the phenomenon of filter membrane fouling; and in addition, ultrasonic cavitation, pyrolysis and mechanical vibration and the persulfate advanced oxidation reaction can produce synergy and can beused for continuous wastewater 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] 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 deficiencies, the present application improves the wastewater treatment technology of persulfate advanced ox...
