A sewage ozone catalytic oxidation treatment device

Abstract

A sewage ozone catalytic oxidation treatment device, comprising a tank body, the upper part of one side of the tank body is fixedly connected to one end of a liquid inlet pipeline with a shut-off valve, and the bottom of one side of the tank body is fixedly connected to one end of a liquid outlet pipeline with a shut-off valve , the top surface of the outer wall of the tank is fixed with an ozone generator, the outlet end of the ozone generator is connected to the upper end of the air intake pipe through a sealed bearing, the air intake pipe runs through the top surface of the tank body and is connected with it in rotation, and the lower side of the air intake pipe The one-way valve is fixedly installed, the lower end of the intake pipe is fixedly installed with a horizontal pipe and communicates with it internally, the outer peripheral bottom of the horizontal pipe is provided with several evenly distributed ventilation holes, and the top surface of the outer wall of the tank is fixedly installed to drive the air intake pipe to rotate. drive unit. The device can realize the reverse rotation of the adjacent two layers of stirring rods, and then can break the air bubbles, make the ozone fully react with the sewage, improve the treatment effect of the sewage, reduce the ozone content in the tail gas, and improve the utilization rate of resources.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a sewage ozone catalytic oxidation treatment device. Background technique [0002] Ozone can not only kill algae in water, but also act as scale and corrosion inhibitors without secondary pollution. It is a strong oxidant that can convert toxic pollutants into non-toxic substances. It has strong oxidation ability in treating wastewater and can decompose general Oxidants are difficult to destroy organic matter, and the reaction is safe and the time is short, so it is widely used in sewage treatment. However, in the existing sewage treatment process, because the ozone bubbles will continue to float in the sewage, the utilization rate of ozone is low. The dissolution rate in water is low, and the sewage treatment effect requires a long time of ozone, so that the discharged gas still contains a large amount of unused ozone, which makes the process cost high and the efficiency is too l...

[0002] Ozone can not only kill algae in water, but also act as scale and corrosion inhibitors without secondary pollution. It is a strong oxidant that can convert toxic pollutants into non-toxic substances. It has strong oxidation ability in treating wastewater and can decompose general Oxidants are difficult to destroy organic matter, and the reaction is safe and the time is short, so it is widely used in sewage treatment. However, in the existing sewage treatment process, because the ozone bubbles will continue to float in the sewage, the utilization rate of ozone is low. The dissolution rate in water is low, and the sewage treatment effect requires a long time of ozone, so that the discharged gas still contains a large amount of unused ozone, which makes the process cost high and the efficiency is too low, and it will be used for a period of time Afterwards, the activity of the ozone catalyst decreases, and the catalyst needs to be replaced, but the existing device is inconvenient to replace
