Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an ozone sewage treatment device. Background Art

[0002] Ozone has strong oxidation and sterilization capabilities and is an ideal reagent for treating domestic and industrial wastewater. Traditional oxidation treatment equipment introduces ozone into the bottom of the reaction tank and uses the rising process of bubbles to oxidize organic matter. The oxidation treatment capacity is relatively low. Patent 202221195355.7 discloses an industrial wastewater treatment equipment based on ozone catalytic oxidation. By setting activated carbon in the box, the catalytic effect of ozone is achieved, which accelerates the oxidation treatment efficiency. However, this technical solution designs the activated carbon as a fixed plate structure. Organic matter is adsorbed on the micropores of the activated carbon, blocking and hindering the further exchange and oxidation of the sewage. After long-term operation, the sewage oxidation treatment capacity gradually decreases until it has the same effect as ordinary oxidation treatment equipment, so further improvement is needed.

[0016] The working principle of this utility model is as follows: the activated carbon particles are spherical and filled in the filter screen, the motor drives the rotating shaft to rotate, the rotating shaft drives the baffle, the baffle and the spiral stirring paddle to rotate, the rotating shaft drives the filter screen and the activated carbon particles to perform rotating centrifugal motion, the ozone sprayed from the ozone inlet pipe below the filter screen moves upward due to the buoyancy, and due to the obstruction of the baffle, the ozone passes through the activated carbon particles for catalytic oxidation, thereby improving the oxidation efficiency of the ozone, and then the ozone bubbles continue to move upward for oxidation until they run out of the sewage and are discharged from the tank through the exhaust port. During long-term operation, organic matter will adhere to the activated carbon. Since the activated carbon particles are always in the rotating centrifugal process, the adhered organic matter will be thrown around by the centrifuge, thereby avoiding the problem of organic matter clogging the activated carbon particles; a spiral stirring paddle is installed at the bottom of the rotating shaft, which can push the sewage The water moves toward the baffle, and then the sewage is deflected by the baffle to form a circular motion, which not only accelerates the gas-liquid mixed oxidation treatment, but also the high-speed flowing sewage can flush the surface of the activated carbon particles, further avoiding the adhesion of organic matter to the surface of the activated carbon particles; since the ozone bubbles gather around the tank after coming out of the activated carbon particles, the mixing plate set up can evenly distribute the floating bubbles to improve the gas-liquid mixing effect; the setting of the first circulation pipe can circulate the unoxidized sewage above the mixing plate to the bottom of the tank for oxidation, thereby accelerating the treatment effect of the sewage; there will be some residual ozone after the sewage is oxidized. By setting the second circulation pipe and the nozzle, the sewage at the bottom will be sprayed on the liquid surface for oxidation treatment with the remaining ozone, thereby improving the treatment effect of ozone and avoiding the air pollution problem caused by large-scale ozone discharge.
