Problems solved by technology

[0004] However, in the above scheme, the waste water is introduced from the water inlet hole, and the waste water is concentrated on the side of the water inlet hole. The contact range between the waste water and ozone is small, the utilization rate and oxidation capacity of ozone are reduced, and ozone needs to be continuously fed in, which increases the operating cost.
