Embodiment 1

[0019] A high-efficiency catalytic oxidation device, such as figure 1 As shown, it includes coagulation air flotation tank 1, intermediate water tank 2, ozone contact oxidation tower 3, high-efficiency catalytic oxidation tank 4, pipeline mixer 7 and high-efficiency sedimentation tank 5 connected in sequence, and ozone contact oxidation tower 3 is connected with ozone generator 6 , the interior of the coagulation air flotation tank 1 is divided into a mixing zone 12 and an air flotation zone 13 by a vertical partition plate 11, there is a gap between the partition plate 11 and the bottom of the coagulation air flotation tank 1, and the side wall of the mixing zone 12 is set There is a sewage inlet 14, the top of the mixing zone 12 is provided with a dosing port 15, the bottom of the mixing zone 12 is provided with a spiral stirring device driven by a motor, and the air flotation zone 13 is divided into a first zone and a second zone by a mesh filter plate 16. Two areas, the to...

Embodiment 2

[0023] Based on the optimization in Example 1, the bottom of the first area is in the shape of an inverted trapezoid, and the lower end of the filter plate 16 is fixed at the edge of the upper end of the bottom of the inverted trapezoid in the first area.

[0024] The bottom of the first area in this embodiment is in the shape of an inverted trapezoid, which is beneficial to the sludge deposition in the coagulation air flotation tank and facilitates sludge discharge.

Embodiment 3

[0026] Optimization is carried out on the basis of Example 2. The spiral stirring device includes a rotating shaft 23 and a spiral plate 24 arranged along the rotating shaft 23. There are more than two spiral stirring devices, and the rotation directions of adjacent spiral stirring devices are opposite.

[0027] This embodiment limits the structure of the spiral stirring device, the effect of the stirring and stirring by the spiral plate is better, and the reaction speed of the dosing is faster, and more than two spiral stirring devices are set at the same time, and the rotation direction of the adjacent spiral stirring devices is opposite, which can Increase the mixing speed of the liquid medicine and improve the effect of the dosing reaction.

Abstract

The invention discloses an efficient catalytic oxidation device, which comprises a coagulation air floatation pool, a middle water box, an ozone contact oxidation tower, an efficient catalytic oxidation tank and an efficient settling pool in sequential communication, wherein the inside of the coagulation air floatation pool is separated into a mixing region and an air flotation region through a vertical separation plate; notches are formed in the separation plate and the bottom of the coagulation air floatation pool; a sewage inlet is formed in the side wall of the mixing region; the top of the mixing region is provided with a chemical adding opening; the air floatation region is separated into a first region and a second region through a reticular filtering plate; a J-shaped floating slag collecting pool is arranged above the first region; the bottom of the first region is provided with an aeration head; the second region is connected with the middle water box through a pipeline. The efficient catalytic oxidation device disclosed by the invention has the advantages that the mixing region and the air floatation region are separated in the coagulation air floatation pool; a stirring device is arranged in the mixing region; an aeration device is arranged in the air floatation region; the air floatation reaction is accelerated, so that the wastewater fast passes through the coagulation air floatation pool so as to remove suspended particulate matters; the catalytic oxidation speed is accelerated; the catalytic oxidation effect is improved.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to a high-efficiency catalytic oxidation device. Background technique [0002] At present, the main process of my country's pharmaceutical and chemical wastewater treatment is the microbial treatment process. The microbial treatment process decomposes the organic pollutants in the wastewater through the metabolism of microbial colonies, and the microorganisms absorb sugar, protein, fat, starch and other low-molecular compounds from it. And oxidize and decompose low-molecular organic matter into CO in an aerobic environment 2 and H 2 O process. However, a certain amount of bioinhibitory pollutants often exist in pharmaceutical and chemical wastewater, especially in the production enterprises of bactericidal and anti-inflammatory drugs. The bioinhibitory pollutants inhibit the growth of microbial colonies that play a key role in the wastewater treatment system...
