In production, other materials are often brightly colored and strongly colored with dyes, which are generally organic compounds, and in the process, a large amount of printing and dyeing wastewater is generated. The printing and dyeing wastewater is the wastewater which is generated by the textile industry and has the most serious pollution, the discharge amount of the printing and dyeing wastewater accounts for more than 10 percent of the total discharge amount of the industrial wastewater, and the printing and dyeing wastewater is one of the most main water pollution sources at present, the water quality of the printing and dyeing wastewater has the characteristics of high pollutant concentration, multiple types, high toxic and harmful components, high chromaticity and the like, and if the printing and dyeing wastewater is directly discharged, the environment is polluted greatly. Therefore, the printing and dyeing wastewater is treated in various ways and discharged after reaching the standard, and the more common method is to oxidize the wastewater by an ozone generator.

The ozone generator for treating waste water is a device for preparing ozone gas and treating waste water. The ozone oxidation has the advantages of strong oxidizability, stable effect, good universality, no secondary pollution and the like in the aspect of water treatment. Ozone is easy to decompose and cannot be stored, so that the ozone needs to be prepared on site and used on site, and an ozone generator is needed to be used in all places where the ozone can be used. However, the ozone generator has a large amount of heat, so that ozone is easily decomposed, and ozone cannot stay in water for a long time after entering water, so that the ozone oxidation efficiency is low, and although ozone oxidation has a certain application in treating toxic pollutants or pollutants incapable of being biodegraded, pure ozone oxidation also has some problems in wastewater treatment, such as strong reaction selectivity of ozone and organic matters. These disadvantages have a great influence on the treatment efficiency of the dye wastewater. Therefore, we propose a flow-control water treatment catalyst catalytic ozonation device.
