A catalytic ozonation wastewater treatment device with high treatment efficiency

Abstract

The invention discloses a catalytic ozonation wastewater treatment device with high treatment efficiency. The catalytic ozonation wastewater treatment device comprises a tower body, wherein a controller is arranged at the periphery of the tower body; a base is fixedly mounted on the bottom surface of the tower body through a bracket; a water outlet pipe is fixedly mounted on one side of the towerbody bottom surface; a gas inlet pipe is fixedly mounted on the other side of the bottom surface of the tower body; an exhaust pipe is fixedly installed on one side of the upper portion of the periphery of the tower body; a water inlet pipe is fixedly installed on the other side of the periphery of the tower body; a lower strip-shaped plate is fixedly installed on the lower portion of the inner wall of the tower body; sliding grooves are formed in the two sides of the inner wall of the tower body respectively; annular supports are movably installed in the tower body; and sliding blocks are fixedly installed on the two sides of the supports respectively and can move up and down along corresponding sliding grooves. Through mutual cooperation of a screw, an upper clamping block, a lower clamping block, a rectangular block, the annular support, a baffle, a discharging pipe and other structures, automatic adding of a catalyst can be achieved, it is not needed to manually add the catalyst after sewage discharging is conducted on the tower body, adding of the catalyst can be completed without opening the tower body by a user, operation is easy, and use is convenient.

Description

technical field [0001] The invention belongs to the field of wastewater treatment, in particular to a catalytic ozonation wastewater treatment device with high treatment efficiency. Background technique [0002] Ozone has strong oxidation ability, fast reaction speed, no sludge and secondary pollution, and is widely used in wastewater treatment. When in use, it is necessary to use a catalyst to catalyze ozone to produce more oxidizing hydroxyl radicals and speed up the oxidation rate of organic matter. The mixing tower of ozone and sewage in the prior art is relatively simple, and there are fixed installations in the tower. The catalyst box injects sewage and ozone into the tower at the same time. When the liquid mixed with sewage and ozone passes through the catalyst, the ozone generates hydroxyl radicals and mixes with the sewage. After the organic matter in the sewage is oxidized, it is easy to precipitate and adhere to the catalyst surface, reducing the The contact area...

Problems solved by technology

When in use, it is necessary to use a catalyst to catalyze ozone to produce more oxidizing hydroxyl radicals and speed up the oxidation rate of organic matter. The mixing tower of ozone and sewage in the prior art is relatively simple, and there are fixed installations in the tower. The catalyst box injects sewage and ozone into the tower at the same time. When the liquid mixed with sewage and ozone passes through the catalyst, the ozone generates hydroxyl radicals and mixes with the sewage. After the organic matter in the sewage is oxidized, it is easy to precipitate and adhere to the catalyst surface, reducing the The contact area with ozone affects the catalytic effect. It is necessary to frequently clean the inside of the tower and the catalyst through a directional cleaning device. During cleaning, sewage treatment cannot be performed, which affects work efficiency.

There is generally no stirring device inside the tower body 1, which may easily lead to insufficient mixing of sewage, ozone and hydroxyl radicals, resulting in reduced sewage treatment effect
