Abstract

The invention provides a device, method and system for ultrasonic coupled integrated wastewater treatment. On the one hand, since membrane separation and a persulfate advanced oxidation reaction during which generated free radicals degrade organic matter, and destroys heavy metal complexes and organic arsenic and organic phosphorus are integrated, and a plurality of pollutants are removed throughadsorption, complexation and co-precipitation of metal ion floc, so that the probability of fouling of a filter membrane is reduced; and since the filter membrane is arranged in an accommodating chamber, iron hydroxide floc which is accumulated on the filter membrane is continuously disturbed simultaneously through the disturbance brought by a mixer, zero-valent iron particles are disturbed on thesurface of the filter membrane, and an on-line membrane cleaning effect is achieved through combination of the in-situ generated free radical oxidants, so that the burden on the filter membrane is further reduced, and fouling of the filter membrane is further prevented; when the device is compared with a non-integrated device of the persulfate advanced oxidation reaction with membrane separation,the phenomenon of fouling of the filter membrane can be reduced greatly; and in addition, a synergistic effect can be generated through ultrasonic cavitation, pyrolysis, mechanical vibration and thepersulfate advanced oxidation reaction, and the device can be applied to 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...
