Water treatment system based on simultaneous production of ozone and hydrogen peroxide

Abstract

The invention relates to a water treatment system based on the technology of simultaneously generating ozone and hydrogen peroxide, which includes a gas-water atomization mixing device, a discharge reaction device and a plurality of sewage treatment devices. The gas-water atomization mixing device generates a gas-water mixture with a certain pressure and enters the In the discharge reaction chamber of the discharge reaction device, a large amount of active substances such as ozone and hydrogen peroxide are produced in the discharge reaction chamber. The strong oxidizing gas enters the next sewage treatment device in turn and circulates in turn. In this water treatment system, strong oxidative active substances such as hydroxyl radicals, hydrogen peroxide and ozone generated by the discharge of the gas-water mixture can not only pass through their own oxidation, but also use the synergistic environment between a large amount of hydrogen peroxide and ozone generated by the discharge. Hydroxyl radicals are rapidly generated under the environment, so as to achieve more rapid and thorough degradation of high-concentration sewage.

Description

technical field [0001] The invention relates to the environmental fields such as plasma treatment of sewage, in particular to a water treatment system based on the simultaneous generation technology of ozone and hydrogen peroxide. Background technique [0002] Due to insufficient anticipation and poor prevention of the negative impact of highly developed industries, people have led to three global crises: resource shortage, environmental pollution, and ecological destruction. Environmental pollution refers to the pollution of the environment by harmful substances due to human factors, which adversely affects the growth and reproduction of organisms and the normal life of human beings. In environmental pollution, water pollution is the biggest problem. In particular, my country's water pollution is particularly serious! [0003] China is a country with severe drought and water shortage. The total amount of fresh water resources is 2,800 billion cubic meters, accounting for...

AI Technical Summary

Problems solved by technology

This method not only has a good decomposition effect on high-concentration pollutants, but also can decompose large-flow and low-concentration pollutants. However, the current plasma devices at home and abroad have the following disadvantages: 1. The discharge electrode is directly in contact with sewage and plasma. Sewage, plasma, and severe corrosion to the electrode make the service life of the discharge device short; 2. The plasma device is relatively complex, with a small processing capacity per unit time and low efficiency, which makes it difficult to realize industrial applications.
