Embodiment 1

[0041] Such as Figure 1-4 As shown, the present invention provides a technical solution, an ozone catalytic oxidation reactor based on sewage treatment, including a sedimentation coagulation tank 1, the side end of the sedimentation coagulation tank 1 is embedded with a connecting pipe 2, and one end of the connecting pipe 2 is installed There is a pretreatment pool 3, a water inlet pipe 4 is installed at the side end of the pretreatment pool 3, and an ozone catalytic oxidation reaction component 5 is installed at one end of the water inlet pipe 4;

[0042] The ozone catalytic oxidation reaction assembly 5 includes a reaction cylinder 501, a rotating shaft 502, a connecting ring 503, a stirring blade 504, a connecting hole 505, an ozone inlet pipe 506, a rotating ring 507, a limiting net 508 and a dredging plate 509;

[0043]A reaction cylinder 501 is installed at one end of the water inlet pipe 4, and a rotating shaft 502 is installed inside the reaction cylinder 501 through...

Embodiment 2

[0050] The present invention provides a technical solution, a sewage circulation treatment method, the gas produced by the catalytic oxidation reaction of the reaction cylinder 501 is transported from the gas delivery pipe 15 to the inside of the gas floating sink 16, and the undissolved ozone with a large molecular weight sinks in the gas floating sink 16 bottom, and enter the pretreatment tank 3 through the gas return pipe 17, and the sewage in the pretreatment tank 3 contacts and reacts with ozone for pretreatment.

[0051] After the sewage is catalyzed and oxidized by ozone, it enters the inside of the detection cylinder 8 through the outlet pipe 7 at the top of the reaction cylinder 501. If the content of suspended solids in the detection cylinder 8 exceeds 30.0 mg / l, close the check valve 10 and turn it three times. Through the valve 14, the detection cylinder 8 is connected to the sedimentation coagulation tank 1, and the sewage enters the sedimentation coagulation tank ...

Abstract

The invention discloses an ozone catalytic oxidation reactor based on sewage treatment, which includes a sedimentation and coagulation tank, a connecting pipe is mounted at the side end of the sedimentation and coagulation tank in an embedded manner; a pretreatment tank is mounted at one end of the connecting pipe; a water inlet pipe is mounted at the side end of the pretreatment tank; an ozone catalytic oxidation reaction assembly is mounted at one end of the water inlet pipe; a reaction cylinder is mounted at one end of the water inlet pipe; a rotating shaft is rotationally mounted in the reaction cylinder through a bearing; a connecting ring is welded to the outer end face of the bottom of the rotating shaft; stirring blades are uniformly welded on the outer end surface of the connecting ring; the device is provided with a reaction cylinder, a rotating shaft, a connecting ring, stirring blades, connecting holes, an ozone inlet pipe, a rotating ring, a limiting net and a dredging plate. In the reactor, the dredging plate is driven to rotate by the impact of ozone and sewage on the stirring blades, so that the sewage, the ozone and the catalyst are in full contact, pores of the limiting net are prevented from being blocked, the oxidation reaction speed of the sewage is increased, and the sewage treatment speed is increased.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an ozone catalytic oxidation reactor for sewage treatment and a sewage circulation treatment method. Background technique [0002] Industrial organic wastewater and cyanide-containing wastewater--ozone is a strong oxidant that can convert toxic pollutants into non-toxic substances. It has a strong oxidation ability in treating wastewater and can decompose organic matter that is difficult to destroy by general oxidants. The reaction is safe and the time is short. The remaining ozone , can be converted into oxygen, not only harmless, but also beneficial, and can be used for disinfection, deodorization, deodorization, color removal, iron manganese removal, phenol removal, cyanide removal, detergent removal, oil removal, etc.; [0003] However, the ozone catalytic oxidation reactor currently used in sewage treatment cannot push the internal catalyst to the direction of sewag...
