Description

technical field [0001] The invention relates to environmental protection equipment and methods, in particular to a high-efficiency gas-liquid blended sewage treatment method and device. Background technique [0002] Ozone (O 3 ) is also known as superoxide, which has strong oxidizing properties. The strong oxidizing property of ozone comes from the fact that ozone can generate highly oxidizing hydroxyl radicals (·OH) after being dissolved in water. Hydroxyl radicals (·OH) can interact with Organic pollutants undergo a series of free radical chain reactions, thereby destroying their structure, oxidizing organic substances with large molecular weight, complex structure, and difficult to biodegrade into small molecules, easily biodegradable organic substances, or directly oxidizing organic substances with small molecular weight, simple structure, and easily degradable degradation. Oxygen (O 2 ), no secondary pollution, is a very environmentally friendly oxide. [0003] At p...

AI Technical Summary

Problems solved by technology

[0011] In order to solve the technical problems of low ozone utilization rate, high energy efficiency and poor treatment effect in the above method, the present invention provides a high-efficiency gas-liquid blending sewage treatment method and device, so that ozone and sewage can be directly and quickly processed under a certain pressure. Fusion, so that the ozone is evenly distributed in the sewage, through the catalytic reaction, the ozone produces a large number of hydroxyl radicals to further oxidize and degrade the sewage, and the remaining gas in the reaction process is recovered and reused
