A multi-stage purification sewage treatment device based on ozone catalytic oxidation

Abstract

A multi-stage purification sewage treatment device based on ozone catalytic oxidation, including a tower body, an ozone delivery pipe is connected to the top of the tower body, a coaxial sleeve is arranged in the tower body, and both ends of the sleeve are connected to the tower body. The inner wall is fixedly connected, the upper part of the sleeve is provided with several overflow holes, the ozone delivery pipe is equipped with a floating ring, the inner bottom of the sleeve is provided with a dial, the bottom of the dial is fixedly connected to the upper end of the rotating shaft, and the rotating shaft runs through the tower body and rotates with it The lower end of the rotating shaft is fixedly installed with the first gear, the first gear meshes with the second gear, and the second gear is connected to the output end of the motor. The barrel runs through the bottom of the housing and is fixedly connected thereto. The device uses the turbulence of sewage to generate negative pressure to inhale ozone, and generates vortex, rotation and collision in the sleeve. The solubility of ozone in sewage is higher than that of Venturi jet mixer.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a multi-stage purification sewage treatment device based on ozone catalytic oxidation. Background technique [0002] From the perspective of the world's ozone technology industry, the main market is the sterilization and purification of water treatment, and the water purification ozone device includes two parts: an ozone source and a gas-water mixing device. The ozone generator should provide ozone with sufficient concentration and output, and the mixing device can dissolve ozone in water with high efficiency, that is, to achieve a certain solubility of ozone. Therefore, a good ozone generator must have an excellent gas-water mixing device, so that ozone can be mixed with water efficiently, so that the solubility of ozone in water can meet complete sterilization. In the current mixing devices, there are ways to accelerate the dissolution by changing the ozone concentration and pr...

AI Technical Summary

Problems solved by technology

In the current mixing devices, there are ways to accelerate the dissolution by changing the ozone concentration and pressure, and there are also multi-stage mixing, etc., but either the process is too long and the area is too large, or the harmless treatment of waste gas is difficult, and there is still a wide range of possibilities. room for improvement
