Titanium anodes for industrial wastewater treatment
Electrolytic oxidation method, or electrochemistry, is called green water treatment because it does not cause pollution in the process of treating water, including industrial water and factory wastewater. The electrode not only plays the role of transferring current, but also plays a catalytic role in the oxidation and degradation of organic substances. With the development of industry, the discharge of organic wastewater is increasing day by day, especially the high concentration wastewater discharged from chemical, food, pesticide and pharmaceutical industries, which has high chroma and high toxicity, contains a large number of biodegradable components, and has seriously polluted rivers, lakes and seas. The new water treatment technology of electrolysis has the advantages of no need to add chemicals, small equipment size, small land occupation, no secondary pollution, and has been used to treat organic polluted wastewater containing hydrocarbons, alcohols, aldehydes, ethers, phenols, etc. COD removal mainly depends on the oxidation reaction on the anode surface, which directly oxidizes and degrades organic matters on the anode surface, so that the organic matters in sewage can be directly or indirectly converted into CO2 and water through electrochemical conversion. The anode potential must be higher than the decomposition potential of organic matter, so the two competitive reactions of organic matter oxidation and oxygen evolution are carried out on the anode.
The precious metal oxide coated titanium anode produced by Dinor Technology has a high oxygen evolution overpotential, and the anode potential is higher than the decomposition potential of organic matter. It is suitable for sewage treatment. The shape of anode is plate type, tube type, mesh type and other forms for users to choose, with reliable quality. The titanium matrix can be reused.
