Electrocatalysis separation film water treatment device

Abstract

The present invention provides an electrocatalytic separation membrane water treatment device, which comprises a shell body and a separation membrane that divides the inner space of the shell body into two parts, wherein, one part is a concentrated liquid space and the other part is a permeation liquid space; the concentrated liquid space comprises a raw water inlet and a concentrated liquid outlet that are arranged on the shell body; the permeation liquid space comprises a permeation liquid outlet arranged on the shell body. The invention is characterized in that a mesh conductive body is arranged inside the concentrated liquid space, at a position facing the separation membrane; the separation membrane and the mesh conductive body are respectively connected with constant current source to form an electron emission zone and an electron reception area; under the effect of the electric field of the constant current source, electron swarm make skip metastasis from the electron emission zone to the electron reception area; while in the metastasis process, OH, O, and H2O2 are produced to form strong oxidation source to decompose the organic matter concentration in the water. The device can be used to provide low-cost operational treatment for organic wastewater, micro-polluted drinking water, reclaimed water reuse, mine water, oil extraction wastewater, swimming pool circulating water and aquaculture circulating water, so as to play a positive role in environmental protection.

Description

technical field [0001] The invention relates to an efficient water treatment technology that integrates the degradation of harmful organic matter in the water body, its filtration, purification, disinfection and sterilization by electrons exciting the particle effect in the water medium to generate hydroxyl radicals under an external electric field, especially an electrocatalytic separation Membrane water treatment device, which can provide low-cost operation treatment for organic wastewater, slightly polluted drinking water, reclaimed water reuse, mine water, oil production wastewater, swimming pool circulating water, aquaculture circulating water, etc. Play an active role in environmental protection. Background technique [0002] Due to the complex nature of organic wastewater, it is difficult for conventional processes to biodegrade or chemically degrade harmful organic substances in wastewater. With the process of industrialization, more and more components of wastewate...
