Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to an ozone catalytic oxidation wastewater treatment device. Background Technology

[0002] When wastewater contains large amounts of recalcitrant organic compounds such as ketones, alcohols, and nitriles, conventional treatment processes are insufficient to meet treatment standards. However, ozone catalytic oxidation can generate strong oxidizing free radicals, such as hydroxyl radicals, which effectively remove organic matter from wastewater during the reaction process, and therefore has been widely used in industrial wastewater treatment.

[0003] Chinese patent document CN220618621U discloses an ozone catalytic oxidation wastewater treatment device. By setting a first guide plate and a second guide plate in the first and second reaction tanks, the device increases the residence time of bubbles and wastewater in the first and second reaction tanks. At the same time, it allows the wastewater to come into contact with ozone on the upper side of the flat tank when it flows, thereby prolonging the contact time between wastewater and ozone and ensuring the wastewater treatment effect.

[0004] However, in the existing technology, although the treatment effect of sewage can be guaranteed by extending the reaction time between sewage and ozone as much as possible, the reaction time is not easy to adjust flexibly. An excessively long reaction time will not only waste the ozone continuously injected into the device, but also restrict the improvement of the sewage treatment efficiency of the device. Therefore, an ozone catalytic oxidation sewage treatment device is proposed. Utility Model Content

[0006] The technical solution adopted in this utility model is as follows:

[0026] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0027] like Figures 1-5 As shown, an ozone catalytic oxidation wastewater treatment device includes a chamber 1 that can contain wastewater to be treated and provide a reaction environment for catalytic oxidation. The chamber 1 is equipped with an adjustment component 2 that can flexibly adjust the volume of wastewater remaining in the device. An air injection component 3 is provided inside and behind the chamber 1 to ensure that the ozone in the wastewater being treated can fully contact the wastewater in the device.

[0028] In this embodiment: the chamber 1 includes an air inlet chamber 101, a liquid inlet chamber 102 is fixedly connected above the air inlet chamber 101, an inspection chamber 103 is fixedly connected above the liquid inlet chamber 102, an intermediate frame 104 is fixedly connected above the inspection chamber 103, an exhaust chamber 105 is fixedly connected above the intermediate frame 104, and a liquid inlet connector 106 is fixedly installed on one side of the liquid inlet chamber 102.

[0029] Ozone used for purifying wastewater is introduced from the bottom of the chamber 1 through the air inlet chamber 101, and wastewater is introduced into the liquid inlet chamber 102 through the liquid inlet connector 106. Two inspection chambers 103 are set above the liquid inlet chamber 102. One of the inspection chambers 103 can be removed to inspect the components inside the chamber 1. The chamber 1 as a whole can still remain stable under the connection of the other inspection chamber 103. One end of the limiting rod 201 is fixed by the intermediate frame 104, and the low support 204 is installed. The exhaust chamber 105 allows some components in the adjustment component 2 located above the intermediate frame 104 to be installed in the chamber 1. At the same time, ozone that has not reacted with wastewater can be guided back to the air injection component 3.

[0030] In this embodiment: the adjustment component 2 includes a drainage component that allows the purified sewage to flow out at a certain height in the device, a drive component that can adjust the height of sewage accumulation in the device, and a transmission component that can transmit power from the drive component to the drainage component. The drainage component includes a limiting rod 201 disposed between the air inlet chamber 101 and the intermediate frame 104. A retractable corrugated pipe 202 is disposed between the air inlet chamber 101 and the limiting rod 201. A drain pipe 203 is fixedly connected above the retractable corrugated pipe 202. The drive component includes a support 204 fixedly installed on the intermediate frame 104 and the exhaust chamber 105 respectively. A lead screw 205 is movably connected between the supports 204. A motor 206 is fixedly connected to the upper end of the lead screw 205. The transmission component includes a transmission frame 207 fixedly connected to the outer side of the lead screw 205. A connecting rod 208 is disposed between the drain pipe 203 and the transmission frame 207.

[0031] The air intake chamber 101 is connected to the retractable bellows 202 via a flange. The retractable bellows 202 and the drain pipe 203 are both slidably connected to the limit rod 201. The retractable bellows 202 and the drain pipe 203 are connected via a flange. The support 204 is rotatably connected to the lead screw 205. The lead screw 205 is connected to the transmission frame 207 via a thread.

[0032] The movable range of the retractable corrugated pipe 202 and the drain pipe 203 within the chamber 1 is limited by the limiting rod 201. The retractable corrugated pipe 202, whose lower end is fixed by the air inlet chamber 101, allows the upper end of the drain pipe 203 to rise and fall to a certain height within the chamber 1 to discharge the sewage from the chamber 1. The lead screw 205 is installed between the intermediate frame 104 and the exhaust chamber 105 by the support 204. The lead screw 205 is driven to rotate by the motor 206. The rotation of the lead screw 205 is transmitted to the drain pipe 203 through the transmission frame 207 and the connecting rod 208, thereby driving the retractable corrugated pipe 202, whose rotation is limited by the limiting rod 201, to extend and retract, and the drain pipe 203 to rise and fall.

[0033] In this embodiment: the air injection component 3 includes an air inlet connector 301 fixedly connected to the air inlet chamber 101, an annular pipe 302 fixedly connected in front of the air inlet connector 301, an aerator 303 fixedly connected to the outer side of the annular pipe 302, a one-way valve 304 fixedly connected behind the air inlet connector 301, a three-way connector 305 fixedly connected behind the one-way valve 304, and a connecting pipe 306 provided between the exhaust chamber 105 and the three-way connector 305.

[0034] Ozone is supplied into the ring pipe 302 sequentially through the three-way connector 305, the one-way valve 304, and the air inlet connector 301, so that the ozone can be evenly distributed in the bottom area of ​​the chamber 1 through the aerator 303 connected to the ring pipe 302. The one-way valve 304 can prevent sewage in the chamber 1 from entering the three-way connector 305, and the connecting pipe 306 can guide the ozone in the exhaust chamber 105 into the three-way connector 305.

[0035] Working principle: When this device is installed and used for sewage treatment, sewage is injected into the chamber 1 at a certain speed through the inlet connector 106, and ozone for purifying sewage is injected into the chamber 1 at a certain speed through the tee connector 305. This allows a certain amount of sewage accumulated in the chamber 1 to fully contact the ozone that is evenly dispersed in the bottom area of ​​the chamber 1. When the sewage level in the chamber 1 is higher than the height of the drain pipe 203, the sewage will overflow into the drain pipe 203 and leave the device. The excess ozone, as it floats upward, will enter the tee connector 305 again along the connecting pipe 306 after reaching the height of the exhaust chamber 105.

[0036] Therefore, in order to ensure the reaction time between wastewater and ozone and the wastewater treatment efficiency of this device, the height of the drain pipe 203 can be adjusted by operating the motor 206 when the wastewater and ozone supply rates are fixed, thereby adjusting the retention time of wastewater in the chamber 1, so that the reaction time between wastewater and ozone is sufficient to purify the wastewater without taking too long.

[0037] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
