High-voltage electro-coagulation sewage treatment system

Abstract

The invention relates to sewage treatment equipment, and in particular relates to a high-voltage electro-coagulation sewage treatment system with high electrochemical conversion efficiency and lower energy consumption. According to the invention, high-voltage dissolved-oxygen type electro-coagulation equipment, high-voltage electrochemical equipment and a high-voltage decomposition tank are connected in series; the high-voltage dissolved-oxygen type electro-coagulation equipment improves the electro-coagulation efficiency through forming an electrochemical flocculation electric field by an electric bipolar plate 1, an electric bipolar plate 2 and an electric monopolar plate 1, forming an electrochemical flocculation electric field by an electric bipolar plate 3, an electric bipolar plate 4and an electric monopolar plate 2, and adopting a high-voltage flocculation mode, generated ions can break molecules with macromolecular structures and complex molecular structures in sewage, and meanwhile the flocculation efficiency is improved; and according to the high-voltage electrochemical equipment, anode plates and cathode plates separately adopt multi-layer composite plates, and a plurality of through holes are additionally arranged in the anode plates and the cathode plates, thus the numbers of the anode plates and the cathode plates are increased, and the entire electrochemical equipment can reach effects such as a high voltage, high efficiency and no appearance of passivation or polarization.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a high-voltage electric flocculation sewage treatment system. Background technique [0002] Domestic sewage is the sewage produced in the process of human production, and it is the main source of pollution of water bodies. It mainly includes feces and washing sewage. With the rapid development of social economy and the increase of population, the discharge of domestic sewage is increasing, which has become a serious obstacle to economic development and the improvement of people's quality of life. People are facing the severe test of double water shortage of resources and water quality. The discharge of domestic sewage from land residents such as cities, villages and towns directly affects people's living environment and the degree of water pollution; the discharge of marine engineering equipment and domestic sewage from ships seriously affects the marine environment. The characteris...

The disadvantage is that different pollutants need to use different chemical reagents

[0009] During the implementation of its structure, it was found that the electrode plates were installed too close to each other, resulting in attachments between the plates, so that the electrochemical conversion efficiency was still not ideal. Slag pipe, making excessive energy consumption
