Introduction of catalytic oxidation tank
The process essence of compound catalytic oxidation is to catalyze the generation of tibinyl radicals through chain reaction. The light radical has a strong oxidation capacity, and its oxidation potential is second only to nitrogen, up to 2.80 V. Shoot and radical can oxidize most of the organic matter in water, especially suitable for the oxidation treatment of organic wastewater and heavy metal complexed wastewater, which are difficult to be degraded by biodegradation or general chemical oxidation. The oxidation reaction generates highly reactive radicals that react with the hard-to-degrade organic matter, causing partial oxidation, coupling or oxidation to form intermediate products with small molecular weight, thus changing their biochemical properties, solubility and coagulation and precipitation. The tibinyl radicals have high electronegativity or electrophilicity. It easily attacks high electron cloud density sites, which determines its unique advantage in treating the oxidation of organic matter containing high electron density such as nitro, sulfonic acid, and chlorine groups. Therefore, the catalytic oxidation process makes up for this deficiency, including the fact that complexes belong to a class of pollutants that are difficult to degrade, and the oxidation using this process can also achieve good effluent results.

In this system, the properties of catalytic oxidation are used to fully oxidize monovalent camel to trivalent camel, reduce toxicity and improve precipitation performance.
Coagulation reaction

The coagulation reaction is to adjust the pH so that Ti3+, Al3+ and Fe3+ in the water body form precipitates and enter the plate and frame filter press for mud-water separation after the linkage of polymeric flocculants.
