Description
Technical Field
The invention belongs to the technical field of sewage treatment, and particularly relates to an ozone catalytic reaction device.
Background
Catalytic ozonation is an advanced oxidation technology commonly used for treating sewage with high organic matter concentration in water treatment technology. The ozone can directly react with organic matters, so that the organic matters in the sewage are removed; ozone can also be decomposed under certain conditions to generate hydroxyl radicals, and the hydroxyl radicals and organic matters are subjected to oxidation reaction. An ozone generator is a device for producing ozone, and since ozone is easily decomposed and cannot be stored, when sewage is treated by an ozone catalytic oxidation technique, ozone needs to be produced on site by the ozone generator and used on site (in a special case, ozone can be stored for a short time).
In the actual sewage treatment process, the ozone generated by the ozone generator can be directly introduced into the sewage treatment tank to treat the sewage, and can also be mixed with liquid through the mixing device to participate in the reaction. The sewage treatment effect depends on the utilization rate of ozone to a great extent, and the contact area between the ozone and the sewage is an important influence factor influencing the utilization rate of the ozone. However, in the existing equipment for treating sewage by using ozone oxidation technology, the contact area between ozone and sewage is small, and the utilization rate of ozone is low. In addition, the existing equipment for treating sewage by using the ozone oxidation technology often has the problems of large occupied area, difficulty in moving positions, trouble in maintenance and the like, and greatly influences the working efficiency.
