With the progress of society, the intensity of environmental protection construction has been continuously strengthened. The water quality of organic wastewater with only primary and secondary treatment will directly lead to eutrophication of water bodies, which can no longer meet the current social and environmental needs. Therefore, deep treatment of organic wastewater is indispensable. However, according to the general laws of the kinetics of decomposition and removal of water pollutants, as the depth of wastewater treatment increases, the difficulty of treatment increases.

Long-term use can easily lead to poor catalytic efficiency of the catalytic net, and in severe cases, the catalytic net will be blocked. For this reason, we proposed an ozone catalytic oxidation device for organic wastewater. Utility Model Content
