[0002] COD is an important indicator of chemical oxygen demand in industrial wastewater. It indicates the number of milligrams of oxygen required by chemical oxidants to oxidize organic matter in water samples under certain conditions. Excessively high COD content in industrial wastewater usually means that the wastewater contains more oxidizable organic matter, which may lead to eutrophication and hypoxia of water bodies, causing serious impacts on the environment.

[0003] In the existing technology, industrial wastewater is often subjected to deep COD treatment using a strong oxidation process. The strong oxidation process device is mainly composed of a reaction cylinder, a pipeline and a support plate.

The industrial wastewater passes through the catalyst particles stacked on the support plate. The catalyst further accelerates the treatment effect of COD in the industrial wastewater.

[0004] However, the catalyst is piled up and placed on a supporting plate, and the industrial wastewater flows through the gaps between the piled catalyst particles. The size of the gaps between the catalyst particles is not unique. When the industrial wastewater passes through the larger gaps between the catalyst particles, it results in the inability to fully obtain the catalytic effect of the catalyst when the industrial wastewater is treating COD, thereby affecting the use effect of the strong oxidation process equipment.

DETAILED DESCRIPTION

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1-8 As shown, a device for deep treatment of COD industrial wastewater by a strong oxidation process comprises: a reaction cylinder 1, a partition 10 and a blocking component.

[0031] The top side ends of the reaction cylinder 1 are fixedly connected to the water inlet pipe 2 and the return pipe 3, respectively. The end of the reaction cylinder 1 away from the water inlet pipe 2 is fixedly connected to the water outlet pipe 8. The return pipe 3 cooperates with the water inlet pipe 2, and the water outlet pipe 8 is communicated with the inside of the reaction cylinder 1. The partition 10 is arranged inside the reaction cylinder 1 and is connected to the inner wall of the reaction cylinder 1. A plurality of storage grooves 16 are opened on the top of the partition 10, and a plurality of water grooves 17 are opened through the bottom of the partition 10. The bottom end of the partition 10 is cooperated and connected with a limiting component. The water groove 17 is communicated with the storage groove 16. The cross-sectional area of the water groove 17 is smaller than the cross-sectional area of the storage groove 16. Industrial wastewater is introduced into the top of the reaction cylinder 1 through the water inlet pipe 2, and then the industrial wastewater is refluxed through the return pipe 3. The industrial wastewater enters the reaction cylinder 1 from the bottom of the reaction cylinder 1 along the return pipe 3. The COD is treated in the reaction cylinder 1, and the industrial wastewater is discharged from the outlet pipe 8 after the COD is treated inside the reaction cylinder 1. The catalyst particles are respectively placed in the storage tank 16 for storage. The industrial wastewater enters the storage tank 16 from the water trough 17 and contacts the catalyst particles. The storage tank 16 can avoid the phenomenon of uneven gaps between the catalyst particles, and realizes the effect of evenly placing the catalyst particles on the partition 10, ensuring that the industrial wastewater can fully contact the catalyst particles, thereby accelerating the oxidation reaction, increasing the oxidation reaction area, and shortening the oxidation reaction time, thereby ensuring that the COD reaches the emission index. The cross-sectional area of the water trough 17 is smaller than the cross-sectional area of the storage tank 16, which can avoid the phenomenon of catalyst particles falling off from the storage tank 16;

[0032] The sealing component is connected to the partition 10 in abutment, and the sealing component is connected to the reaction tube 1. When the catalyst particles are placed on the partition 10 and then installed in the reaction tube 1, the partition 10 is installed through the limiting component, and the limiting component provides limiting support for the partition 10. Then the sealing component is used to press and seal the partition 10, thereby achieving the effect of installing the partition 10.

[0033] In some specific embodiments, the bottom end of the reflux pipe 3 is cooperatively connected to the reaction tube 1, and a gas-water mixer 4 is fixedly connected to the center of the reflux pipe 3, and an air inlet pipe 5 is fixedly connected to the side end of the gas-water mixer 4. A number of distributors 9 are fixedly connected to the bottom end of the inner wall of the reaction tube 1, and the distributor 9 cooperates with the reflux pipe 3. When industrial wastewater refluxes through the reflux pipe 3, the ionized gas is introduced into the gas-water mixer 4 through the air inlet pipe 5, and the ionized gas and industrial wastewater are simultaneously introduced into the bottom of the reaction tube 1 through the reflux pipe 3. The ionized gas and industrial wastewater are introduced into the interior of the reaction tube 1 through the distributor 9. The ionized gas can ensure the oxidation effect of the industrial wastewater and further enhance the effect of the industrial wastewater in treating COD. The distributor 9 can fully mix the ionized gas and industrial wastewater and pass them into the interior of the reaction tube 1, thereby ensuring that the ionized gas and industrial wastewater are evenly in contact with the catalyst particles. When the catalyst promotes the reaction of the ionized gas and the COD of the industrial wastewater, the catalyst is not consumed, thereby reducing the cost of COD treatment of the industrial wastewater.

[0034] In some specific embodiments, there are two groups of limiting assemblies and they are respectively located on both sides of the partition 10. The limiting assemblies include: a support plate 12 and a limiting plate 13. The support plate 12 is fixedly connected to the inner wall of the reaction cylinder 1. Limiting grooves 14 are respectively opened at both ends of the bottom of the partition 10. The limiting plate 13 is clamped in the limiting groove 14 and is slidably connected to the inner wall of the limiting groove 14. The limiting plate 13 is fixedly connected to the top of the support plate 12. When the partition 10 is installed on the limiting assembly, the limiting groove 14 opened on the partition 10 is slid along the limiting plate 13. The support plate 12 provides support for the partition 10, and the limiting plate 13 and the inner wall of the limiting groove 14 are clamped and connected to provide a limiting effect for the partition 10.

[0035] In some specific embodiments, a plugging port 15 is provided at one end of the reaction tube 1 away from the reflux pipe 3, and the plugging port 15 cooperates with the partition 10, and the plugging port 15 cooperates with the plugging assembly. The plugging assembly includes: a plugging plate 7 and a sealing gasket 19, the plugging plate 7 is abutted against the outer wall of the reaction tube 1, and the side end of the partition 10 is fixedly connected with a connecting plate 18, the sealing gasket 19 has plasticity, the sealing gasket 19 is abutted against the inner wall of the plugging port 15, the sealing gasket 19 is abutted against the connecting plate 18, and the sealing gasket 19 is fixedly connected to the plugging plate 7. The two ends of the plugging plate 7 respectively penetrate the interior of the reaction tube 1 and are provided with threaded holes 11, and the threaded holes 11 are connected with bolts 6. When the catalyst and other substances in industrial wastewater placed on the partition 10 When the contact loses its activity, the catalyst needs to be replaced, the partition 10 is removed from the sealing port 15, and then the catalyst particles placed on the partition 10 are replaced, and then the partition 10 is installed on the limiting assembly, and the sealing assembly is installed. The staff controls the sealing gasket 19 to be inserted into the sealing port 15, and the sealing gasket 19 and the inner wall of the sealing port 15 are abutted. At the same time, the sealing gasket 19 and the connecting plate 18 are abutted. The sealing gasket 19 is plastic and deforms. The sealing gasket 19 seals the sealing port 15. When the sealing plate 7 and the outer wall of the reaction tube 1 are abutted, the bolt 6 is rotated and threaded in the threaded hole 11, thereby fixing the sealing plate 7 on the reaction tube 1, thereby abutting and fixing the partition 10.
