Description

Technical Field

[0001] This utility model relates to the field of wastewater ozone oxidation treatment technology, and in particular to a wastewater ozone oxidation device. Background Technology

[0002] Wastewater ozone oxidation is a technology that uses the strong oxidizing properties of ozone to purify wastewater. It is widely used in the field of wastewater treatment. Ozone reacts directly with organic pollutants in wastewater, decomposing large organic molecules into smaller ones, or directly oxidizing them into inorganic substances such as carbon dioxide, water, and inorganic salts. Existing wastewater ozone oxidation devices consist of an ozone generator, a wastewater container, and an aerator. Because wastewater often contains impurities, these impurities fall into the aerator, easily causing blockages and reducing the efficiency of the wastewater ozone oxidation device and the aerator. Therefore, existing wastewater ozone oxidation devices add filters to block impurities. However, with prolonged use, the filters accumulate a lot of impurities, reducing their filtering effect and also hindering the oxidation reaction between ozone bubbles and wastewater.

By setting up the tank 1 and the ozone generator 2, sewage is injected into the tank 1 through the sewage inlet pipe 11, ozone is generated by the ozone generator 2, and then input into the connecting pipe 10. In pipe 3, the ozone gas enters the microporous aerator 4 through connecting pipe 3. The ozone gas is dispersed into extremely small bubbles by the microporous aerator 4 and released into the sewage, where it reacts with the organic matter in the sewage to oxidize.

This solves the problem that the accumulation of impurities on the upper end of the filter screen 6 will block the ozone bubbles from reacting with the sewage to oxidize. The sewage discharge pipe 12 is set to facilitate the discharge of liquid from the tank 1. The tail gas decomposition device 10 is set to prevent ozone from being emitted into the atmosphere and causing environmental harm, and can reduce the ozone concentration to a safe level.

Multiple microporous aerators 4 connected to the connecting pipe 3 are installed at equal intervals on the upper end of the connecting pipe 3. By setting the fixing frame 13, the two ends of the connecting pipe 3 are fixed to the inside of the tank body 1, which facilitates the improvement of the stability of the installation of the connecting pipe 3. By setting multiple microporous aerators 4 connected to the connecting pipe 3, the ozone bubbles inside the tank body 1 are more evenly distributed, so as to achieve a more complete oxidation effect.
