Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to sewage treatment equipment based on heterogeneous ozone catalytic oxidation technology. Background Art

[0002] Ozone catalytic oxidation technology is an advanced oxidation technology that combines the strong oxidizing property of ozone with the catalytic action of catalysts. It produces highly reactive free radical intermediates, especially hydroxyl radicals, on the catalyst surface through ozone molecules, thereby achieving oxidative decomposition of pollutants in water. The treatment process of this technology usually includes wastewater input, ozone addition, catalyst reaction, exhaust gas treatment and other steps, and is usually used in sewage treatment.

[0003] When the ozone mixed gas enters the reaction tower, it tends to pile up and cannot be evenly distributed. In the tower, there is a large amount of sewage with a large density and concentration. In this case, it cannot be fully guaranteed that the wastewater can fully contact with the ozone mixed gas. Since the reaction between ozone and polluted water sources is not sufficient, this will have an adverse effect on the sewage treatment effect. This situation is not conducive to the stability of sewage treatment, and fluctuations and instability may occur during the sewage treatment process, thereby reducing the efficiency of sewage treatment. At the same time, it will also lead to the failure to effectively remove some pollutants, affecting the final sewage treatment quality and failing to meet environmental protection requirements and standards.
