Sewage treatment with titanium anode including domestic sewage, industrial water, factory wastewater treatment process, the electrode not only plays a role in transmitting current, but also plays a catalytic role in the oxidation of organic matter degradation, in this process because it does not cause pollution, known as green water treatment.

Electrolytic oxidation method or electrochemistry, the water including industrial water, factory wastewater treatment process, the electrode not only plays a role in transmitting current, but also plays a catalytic role in the oxidative degradation of organic matter, in this process because it does not cause pollution, known as green water treatment. With the development of industry, the discharge of organic wastewater is increasing, especially the high-concentration wastewater discharged by the chemical, food, pesticide and pharmaceutical industries, which has high chroma and toxicity and contains a large number of biodegradable components, seriously polluting rivers, lakes and seas. The new technology of electrolysis water treatment has the advantages of no need to add chemical agents, small equipment size, small footprint, no secondary pollution, and has been used to treat organic pollution wastewater containing hydrocarbons, alcohols, aldehydes, ethers, phenols and so on. The removal of COD mainly depends on the oxidation reaction on the anode surface, which directly oxidizes and degrades organic matter on the anode surface, so that the organic matter in the sewage can be directly or indirectly converted into CO and water through electrochemical conversion. The anode potential must be higher than the decomposition potential of organic matter, so the oxidation and oxygen evolution of organic matter are two competitive reactions on the anode.
