Electrolysis module based on BDD electrode and water treatment system

Abstract

The invention provides an electrolysis module based on BDD electrodes. The electrolysis module comprises a water flow guiding module and an electrolysis module body. The electrolysis module is arranged in the water flow guide module; the electrolysis module comprises a BDD electrode, the BDD electrode comprises a main body part and a plurality of branch parts arranged on the two sides of the main body part, and the main body part and the branch parts on the two sides of the main body part form a fishbone-shaped structure. The BDD electrode of the electrolysis module is of a fishbone-shaped structure, compared with an existing pore plate electrode structure, gas generated during electrolysis cannot block pores, under the combined action of the water flow guide module, the gas is easy to discharge, efficient discharge of gas products is achieved, the probability of particulate matter blockage can be reduced, the effective electrolytic reaction area is guaranteed, and the service life of the electrolysis module is prolonged. And the electrolysis efficiency and the water treatment efficiency can be improved. The invention further provides a water treatment system comprising the electrolysis module, and the water treatment system is matched with a filtering module and a gas-liquid mixing module, so that the treatment effect is effectively improved.

Description

technical field [0001] The invention relates to the technical field of electrochemistry, in particular to an electrolysis module and a water treatment system based on a BDD electrode. Background technique [0002] Boron-doped diamond (BDD) electrode is a BDD electrode made by depositing a boron-doped diamond film on a substrate by vapor deposition. Viruses, bacteria, organic pollutants, etc. are oxidized. In addition to the advantages of high oxygen evolution potential and high electrocatalytic activity, BDD electrodes also have excellent chemical stability and can resist electrode loss caused by electrochemical corrosion during long-term electrolytic applications. They are widely used in disinfection and water treatment. For example, for watering cans, humidifiers, vegetable washing machines, washing machines, air purifiers, water purifiers, deodorizers, sewage treatment machines, etc. [0003] However, the existing BDD electrode technology still has the following problem...

Problems solved by technology

[0006] The present invention provides an electrolysis module and water treatment system based on BDD electrodes to solve the problem that the gases such as hydrogen, ozone and oxygen produced during the electrolysis of the existing BDD electrodes are difficult to be discharged in time, which reduces the effective working area and hinders the electrolysis reaction Efficient; when the water to be treated contains particulate matter or impurities are deposited during the electrochemical reaction, it is easy to block the vent hole (or tank) and reduce the electrolysis efficiency.
