A high-flux electrochemical filtration sewage treatment device

Abstract

The invention is a high-throughput electrochemical filtration sewage treatment device, which comprises an electrochemical filtration reactor (1), a circulating pump (2), a flow meter (3) and a direct current power supply (4). Among them: the electrochemical filtration reactor (1) assembly consists of a cylinder (5), a support (6), a carbon nanotube membrane electrode (7) and a connecting part (8), a porous insulating rigid diaphragm (9), a porous insulating It consists of a flexible membrane (10) and a sealing component. The porous insulating flexible membrane separates the two layers of carbon nanotube membrane electrodes, and the two porous insulating rigid membranes are used as the support of the electrodes to squeeze the electrodes and the electrode connecting parts tightly. Under the suction or pressure delivery of the circulating pump, the water flow can pass through the carbon nanotube membrane electrode of the electrochemical filtration reactor vertically at high speed, and take away the air bubbles generated on the electrode without disintegrating the electrode or causing mechanical damage. The invention has the advantages of simple structure, high reaction rate, low operation cost, convenient operation and stable operation.

Description
