Efficient ozone catalytic oxidation water treatment system and control method

Abstract

The invention provides an efficient ozone catalytic oxidation water treatment system and a control method. The efficient ozone catalytic oxidation water treatment system comprises a box body, a sewagecirculation unit and an ozone circulation unit; one side of the box body is designed to be a feeding side, the other side of the box body is designed to be a discharging side; a sewage tank is arranged in the box body, and a catalytic unit is arranged above the sewage tank; the sewage circulation unit comprises a plurality of circulation assemblies, and the circulation assemblies can collect sewage in different areas of the sewage tank and spray the sewage above the corresponding collection areas; the ozone circulation unit comprises a venturi ejector and a circulation pipeline, the venturi ejector is arranged on the feeding side of the box body, a feeding port of the venturi ejector is connected with an air pump, a discharging port is connected with the sewage tank, and a suction port isconnected with the top of the box body through a circulation pipeline. According to the efficient ozone catalytic oxidation water treatment system and the control method, the utilization rate of ozone and the purification effect on sewage can be improved.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment, and in particular relates to an efficient ozone catalytic oxidation water treatment system and a control method. Background technique [0002] With the frequent outbreak of water pollution incidents, people pay more and more attention to sewage treatment. Ozone has strong oxidation properties and can oxidize various pollutants in sewage. Therefore, ozone catalytic oxidation technology has been widely used in the field of water treatment. focus on. When ozone is used for catalytic oxidation of sewage, the contact between ozone and catalyst can generate a large number of highly oxidizing free radicals, and the use of oxidizing free radicals can oxidize and decompose organic pollutants in water, and finally achieve the purpose of water purification. [0003] However, due to the low solubility of ozone in water, the ozone injected into the wastewater will quickly dissipate into the environm...

AI Technical Summary

Problems solved by technology

[0003] However, due to the low solubility of ozone in water, the ozone injected into the wastewater will quickly dissipate into the environment. Therefore, the mixing effect of ozone and sewage in the existing device is poor, and the ozone injected into the device cannot be effectively utilized.

The residual ozone in the device will be discharged to the outside with the purified sewage, thus polluting the external environment

In addition, when the ozone utilization rate is low, the purification effect of the sewage will become poor, and the COD removal rate in the sewage is only about 20%, so the pollutant content in the sewage cannot be effectively reduced
