Wastewater treatment ozone catalytic oxidation reactor

Abstract

The invention relates to a wastewater treatment ozone catalytic oxidation reactor, which comprises an ozone catalytic oxidation reaction cavity. An ozone catalyst filler layer is arranged in the ozonecatalytic oxidation reaction cavity. An introduced water distributing device and a gas-water mixed liquid distributing device are arranged under the ozone catalyst filler layer. An effluent weir plate is arranged above the ozone catalyst filler layer. The inlet of the gas-water mixed liquid distributing device is connected to the outlet of a return pipe. The inlet of the return pipe is communicated with the ozone catalytic oxidation reaction cavity on the lower edge of the effluent weir plate. The pipeline of the return pipe is provided with a reflux pump and a water ejector. The gas inlet ofthe water ejector is connected to an ozone generator. The water ejector sucks ozone through a negative pressure and fully mixes ozone with wastewater; water distribution and gas distribution are performed at the same time; the mass transfer efficiency is high; the ozone utilization rate is high; the catalytic oxidation effect is good; moreover, an ozone and wastewater mixing device is arranged out of a pool, and thus the maintenance is convenient and safe.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an ozone catalytic oxidation reactor for wastewater treatment. Background technique [0002] At present, the ozone gas distribution method of the ozone catalytic oxidation reactor adopts microporous aerators. Due to the high failure rate of the microporous aerators in a highly oxidizing environment, frequent replacements, difficult replacement operations and potential safety hazards, affect continuous Wastewater treatment production. This patent uses water ejector negative pressure to suck ozone and fully mix it with waste water, and distribute water and air at the same time. The mass transfer efficiency is high, the ozone utilization rate is high, and the catalytic oxidation effect is good. The ozone and wastewater mixing device is installed outside the tank, which is safe and convenient for maintenance. Contents of the invention [0003] The technical problem to be s...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art, to provide a wastewater treatment ozone catalytic oxidation reactor, to solve the problem of poor mixed mass transfer effect of ozone and wastewater in the current ozone catalytic oxidation reactor, low ozone utilization rate, catalytic The oxidation efficiency is low, and the ozone escapes seriously from the reactor, which causes the problem of heavy ozone odor in the air on site
