Titanium anode mainly treat sewageWorking Principle
Titanium anode mainly treat sewage by means of electrocatalytic oxidation. Under the action of an electric field, the active coating on the surface of titanium anode can generate strongly oxidizing substances such as hydroxyl radicals. These strongly oxidizing substances can undergo oxidation reactions with pollutants such as organic matter, ammonia nitrogen, and heavy metal ions in sewage, decomposing them into harmless substances such as carbon dioxide, water, and inorganic ions.
In the field of wastewater treatment, the removal rate of COD is one of the important indicators to measure the effect of wastewater treatment. Due to the many types of wastewater and their different properties, there are various methods for treating wastewater. Chemical methods for treating wastewater need to add chemical substances such as oxidants and flocculants, and the equipment has a large volume, occupies a large area, and the subsequent treatment is complex, so the cost is high; biological treatment technology can only treat biodegradable substances in wastewater, so it can only remove COD and chroma in wastewater to a limited extent; while electrochemical methods for treating wastewater generally do not need to add chemical substances, the equipment has a small volume, occupies less area, is easy to operate flexibly, has less sludge, and the post-treatment is extremely simple. It is usually called an environmentally friendly and clean treatment method. Make the application of electrochemical methods in the field of sewage treatment more effective and the application scope wider.
Electrooxidation method uses the high potential of the anode to degrade toxic compounds in the solution. Electrooxidation can be divided into direct oxidation and indirect oxidation. CN- in electroplating industrial wastewater can be directly oxidized by titanium electrodes. At the same time, direct oxidation also has the functions of desulfurization and sterilization. Indirect oxidation is that in the reaction process of titanium anode, chemically active substances with strong oxidizing properties are preferentially generated, and then these substances are used to oxidize and decompose refractory substances. Ag2+, Co3+ and Fe3+ can all be used as oxidation intermediates of organic substances. Indirect oxidation has been verified to be effective in the oxidation process of benzene, phenol, oil and chloride.

production
1. Substrate treatment: it needs to be treated by roughing, cleaning and removing oil, which can increase the compactness of catalytic.
2. Brushing coating:After substrate treatment, it will be proceeded brush coated. The main coated content is platinum group metal, which is a kind of mixed solution.Then, heat treatment will be going on after drying.The whole procedure need to be repeated many times. This method is better to form thin oxide catalytic that is lamellar adhere to substrate surface.
