Embodiment 1

[0036] In the wastewater treatment of a certain chemical industry, 10kg / h ozone is used for wastewater treatment, and an exhaust gas discharge pipe is installed on the top of the ozone contact oxidation tank. The ozone tail gas is collected through the pipeline and enters the inlet 1.1 of the packing absorption tower 1 of the gas-liquid subsystem. Inside, the thickened FRP support grid plate 1.2 enters the packing layer 1.3, and after the rising gas fully contacts with the liquid sprayed from the upper spray pipe 1.4, it enters the bottom of the demister tower 2 through the gas outlet pipe 1.5, and the gas and the flushing pipe of the lower demister The liquid is sprayed out in 2.2, and after preliminary gas mist separation in the lower corrugated plate demister 2.1, the liquid is sprayed out from the flushing pipe 2.4 of the upper corrugated plate demister, and the final gas mist separation is carried out in the upper corrugated plate demister 2.3, and the clean gas passes thro...

Abstract

The invention relates to a method for destructing ozone tail gas in wastewater treatment, and belongs to the technical field of wastewater treatment. The method comprises the steps that the ozone tailgas is dried through a gas-liquid separation system and a temperature-control reaction device and then the dried ozone is introduced into an ozone tail gas destructor to be treated so as to obtain gas A; then the gas A is sucked into a spray tower of a deodorization system through a fan; and then the gas A is discharged at high altitude through a chimney with the height of 30m. According to the method, the gas-liquid separation system and the temperature-control reaction device are additionally arranged in front of the ozone tail gas destructor, the gas is effectively dehumidified and dried,and therefore the time when a catalyst in the destructor is affected with damp and loses efficacy is slowed down, the effective use time of the catalyst is prolonged, the use efficiency of the catalyst is improved, and the replacement frequency of the catalyst is lowered; and the outlet gas of the ozone tail gas destructor is mixed with odor VOC through the fan, the outlet gas and the odor VOC together enter the spray tower, residual ozone and odor are subjected to redox reaction, so that the odor treatment effect is improved, meanwhile, the concentration of the ozone in the gas is further degraded, finally, all the gases are discharged at high altitude through the chimney with the height of 30m, and therefore the concentration of the ozone can be enabled to be 0.01mg / L or less.

Description

technical field [0001] The invention relates to a method for improving the ring-breaking efficiency of ozone tail gas in wastewater treatment, and belongs to the technical field of wastewater treatment. Background technique [0002] In wastewater treatment, the tail gas discharged from the ozone contact tank still contains a certain amount of ozone. If it is directly discharged into the atmosphere, it will cause atmospheric environmental pollution. The environmental emission regulation of ozone tail gas is 0.3mg / L. [0003] There are two types of ozone exhaust destroyers: electric heating destruction and chemical method destruction. The electric heating destruction uses a heater to instantly heat the exhaust gas passing into the destroyer to above 300°C, and utilizes the principle that ozone can be rapidly decomposed at high temperature to destroy and decompose ozone at high temperature. Although electric heating can effectively and quickly decompose ozone, but because the...
