Wireless electric flocculation water treatment device based on bipolar electrochemical principle

Abstract

The invention discloses a wireless electric flocculation water treatment device based on bipolar electrochemical principles. The device comprises an electrolytic tank, a power supply, a main anode and a main cathode, wherein the main anode and the main cathode are arranged inside the electrolytic tank and are respectively electrically connected with the power supply; at least one bipolar electrode is arranged between the main anode and the main cathode inside the electrolytic tank; and the main surface of the bipolar electrode or a main shaft is not perpendicular to the direction of an electric field line in the electrolytic tank. As the bipolar electrode which is not connected with an external circuit is arranged between the main anode and the main cathode, and the main surface or the main shaft is not perpendicular to the direction of the electric field line in the electrolytic tank, the bipolar electrode is subjected to an electrochemical reaction under polarization of the electric field of a solution, a high-activity flocculant is generated, meanwhile action of electroflotation, oxidation reduction and the like are resulted, dissoluble and suspended pollutants and colloids in water can be effectively converted and removed, and thus the purpose of sewage purification is achieved. The wireless electric flocculation water treatment device has the characteristics that the structure is simple, electrodes are conveniently replaced, electrode materials are saved, the purification efficiency is high, blocking is not easily caused and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of water treatment equipment, and specifically relates to a radio flocculation water treatment device based on the bipolar electrochemical principle, which has the advantages of simple structure, convenient electrode replacement, saving electrode materials, high purification efficiency, not easy to block, and low cost. Background technique [0002] A bipolar electrode (BPE, bipolar electrode) refers to a conductor that is immersed in the electrolyte between the anode and the cathode that is not connected to an external power source. The side of the anode close to the driving electrode acts as a cathode, and a reduction reaction occurs, while the side close to the cathode of the driving electrode acts as an anode, and an oxidation reaction occurs. Both ends can simultaneously undergo oxidation and reduction reactions, and one electrode can simultaneously act as an anode. The role of anode and cathode. [000...
