The utility model belongs to the field of sewage treatment, in particular to a photocatalytic intelligent device capable of cyclically degrading high-concentration organic matter in industrial waste water.

Background technique

With the rapid development of industry, the types and volume of waste water have increased rapidly, and the pollution of water bodies has also become increasingly serious, seriously threatening human health and safety. Industrial wastewater has the characteristics of complex composition, large changes in water quality and quantity, dark color, and low biodegradability. The COD value of high-concentration industrial wastewater can be as high as 10 ⁵ mg/L, and the chromaticity can reach more than 4000 times. There are also more and more ingredients, some even contain carcinogenic, mutagenic, and distortion-causing organic substances, which are increasingly threatening and harmful to the environment, especially the water environment, and have become one of the most difficult industrial wastewater recognized at home and abroad.

Traditional industrial wastewater treatment methods include physical and chemical methods, chemical methods, physical adsorption methods, biochemical methods, and electrochemical methods. These methods are costly, high in operating costs, limited by applicable conditions, and have unsatisfactory treatment effects. It is difficult to meet the technical (weak oxidation ability or selective oxidation) and economical (complex equipment, high cost) purification treatment of this type of organic matter. The requirements are becoming more and more difficult to deal with.
