Catalytic ozonation treatment device for sewage

Abstract

A catalytic ozonation treatment device for sewage comprises a tank body, the upper portion of one side of the tank body is fixedly connected with one end of a liquid inlet pipeline with a stop valve,the bottom of one side of the tank body is fixedly connected with one end of a liquid outlet pipeline with a stop valve, and an ozone generator is fixedly installed on the top face of the outer wall of the tank body. The gas outlet end of the ozone generator is connected with the upper end of a gas inlet pipeline through a sealing bearing, the gas inlet pipeline penetrates through the top surfaceof the tank body and is rotationally connected with the top surface of the tank body, a one-way valve is fixedly mounted on the lower side in the gas inlet pipeline, and a transverse pipe is fixedly mounted at the lower end of the gas inlet pipeline and communicates with the interior of the gas inlet pipeline;A plurality of evenly-distributed air holes are formed in the bottom face of the periphery of the transverse pipe. A driving device capable of driving the gas inlet pipeline to rotate is fixedly mounted on the top surface of the outer wall of the tank body. According to the device, reverse rotation of two adjacent layers of stirring rods can be realized, so that bubbles can be crushed, ozone and sewage are fully reacted, the sewage treatment effect is improved, the ozone content in tail gas is reduced, and the resource utilization rate is increased.

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
