Any inquiry of Titanium electrode for ammonia nitrogen wastewater treatment,please contact us:
Titanium electrodes for ammonia nitrogen wastewater treatment include domestic sewage, industrial water, and factory wastewater. In the process of treating domestic sewage, industrial water, and factory wastewater, the electrode not only plays the role of transmitting current, but also catalyzes the oxidative degradation of organic matter. In this process, because it does not cause pollution, it is called green water treatment. With the development of industry, the discharge of organic wastewater is increasing, especially the high-concentration wastewater discharged from the chemical, food, pesticide and pharmaceutical industries. It has high chromaticity and high toxicity, and contains a large number of bio-refractory components, which seriously pollutes rivers and lakes. The new technology of water treatment by electrolysis has the advantages of no need to add chemicals, small equipment size, small footprint, and no secondary pollution. It has been used to treat wastewater containing organic pollution such as hydrocarbons, alcohols, aldehydes, ethers, and phenols. The removal of COD mainly relies on the oxidation reaction of the anode surface, which directly oxidizes and degrades the organic matter on the anode surface, so that the organic matter in the sewage can be converted into CO2 and water directly or indirectly through electrochemical conversion. The anode potential must be higher than the decomposition potential of organic matter, so two competing reactions of organic matter oxidation and oxygen evolution are carried out on the anode.
The titanium anode for electrocatalytic oxygen, ammonia, and nitrogen wastewater treatment produced by Baoji Highstar Titanium Metal can generate a large number of O, H, N, OH, CH2 and other atoms and ionic active groups during electrolysis. The salt is converted into free ammonia to the maximum extent; meanwhile, the partial pressure of ammonia in the wastewater and other mixed gases is reduced, the desorption process and transfer rate of the free ammonia released are accelerated, and the converted free ammonia can be quickly and fully separated from the wastewater. This high-efficiency composite catalyst also has strong redox properties, and has chemical nitrification for wastewater. It can convert free ammonia and other nitrogen-containing substances in wastewater into nitrogen through nitrification and then denitrification.
