Electric flocculation purification device

Abstract

The invention discloses an electric flocculation purification device. The device comprises a cabinet body, a plurality of electrode plate groups and a plurality of pairs of electrode columns; the plurality of electrode plate groups are arranged in the cabinet body at intervals; each pair of electrode columns extends and penetrates through the cabinet body to be electrically connected with electrode plates in one electrode plate group, at least one partition plate is arranged between every two adjacent electrode plate groups, a pair of opposite side edges of each partition plate are connected with the cabinet body, and gaps are formed between the side edges, adjacent to the opposite side edges, of the partition plates and the cabinet body; and the gaps form a flow channel communicated with the space where the adjacent electrode plate groups are located. According to the electric flocculation purification device disclosed by the invention, the problems of poor water flow performance, unequal current density during the electric flocculation working period of all the electrode plates, high possibility of electrode plate passivation, high electric energy consumption and the like are solved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment in the catering industry, in particular to an electrocoagulation purification device, especially a pipeline type electrocoagulation purification device. Background technique [0002] The electrocoagulation method removes COD, organic matter, heavy metals, salt, etc. in the sewage. The electrocoagulation method will not be doped with other chemical components and will not cause secondary pollution, but the electrocoagulation method also has its shortcomings; one is the use of electric energy The consumption is large, which affects the working cost; secondly, the passivation of the plate affects the efficiency of continuous work. [0003] The electrocoagulation plates in the prior art are placed in the water tank in the form of multi-pole arrays arranged horizontally, and the water intake of the plates is relatively large. The water flow performance between the plates is not the same, ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is also to provide an electrocoagulation purification device, which is used to solve the problems of poor water flow performance of the existing device, unequal current density during the electrocoagulation work of each plate, easy plate passivation, and large power consumption.

[0007] The object of the present invention is also to provide an electrocoagulation purification device, the slender electrode plate channel of sewage flows between the slender electrode plates, prolonging the electrocoagulation time of sewage in the pipeline type box, and solving the problem caused by uneven water flow. It is easy to passivate the place where the water flow rate of the plate is small, and prolonging the treatment time of sewage between the plates also improves the purification effect of sewage
