[0002] Wastewater treatment: the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people. However, when sewage is treated, organic matter in the sewage will emit foul-smelling gases, and the pollution source needs to be deodorized.

[0003] In most of the existing sewage treatment deodorization problems, the odor is usually purified by using activated carbon to purify the odor by adsorbing malodorous gases. When purifying the odor, the use time of the activated carbon will affect the purification effect, resulting in incomplete purification of the odor in the sewage. Therefore, the sewage needs to be purified and deodorized again, which increases the cost and time of purification and causes waste of resources. Therefore, this scheme proposes a sewage deodorization equipment for sewage treatment plant to solve the above problem. Utility Model Content

After the disinfectant is sprayed, it reaches the emission standard and is discharged through the exhaust pipe, which can avoid the impact of the post-reaction gas emission on the environment. The disinfectant inside the spray chamber will be gathered to the disinfection water pump due to the special shape of the liquid collecting bucket for repeated reflux and use, reducing the waste of disinfectant.

[0023] When deodorizing the purified sewage, it is necessary to inject the sewage from the sewage injection pipe 4 into the interior of the deodorization reaction box 1 to fill the sewage reaction chamber 5. When the sewage injection pipe 4 is filled, the ozone injection pipe 6 simultaneously injects ozone into the sewage reaction chamber 5. At this time, the motor 3 starts its output shaft to drive the stirring blade 7 to rotate between each layer of the stratified baffles 9. When the stirring blade 7 rotates, the spoiler 8 rotates synchronously to fully contact and stir the ozone with the sewage. When the sewage passes through the adsorption filter 10 set on the stratified baffle 9, it will be purified and adsorbed by its characteristics. Therefore, the sewage passes through the multiple layers of stratified baffles 9 to give the sewage and ozone more reaction time and purification times, thereby improving the deodorization effect of the sewage. The ozone passes through the ozone injection pipe 6 inside the sewage reaction chamber 5 and uniformly contacts and reacts with the injected sewage. Ozone has strong oxidizing properties and decomposes in water to form hydroxyl free radicals with strong oxidizing groups, which can quickly remove organic pollutants in the sewage, and the main components of the odor in the sewage are decomposed by ozone without causing secondary pollution.

[0024] A drainage pipe 16 is fixedly connected to the surface of the deodorizing reaction box 1 , and the drainage pipe 16 is located above the uppermost layered baffle 9 .

[0025] After being purified, the sewage will be discharged through the drain pipe 16 above the stratified baffle 9 for testing. After passing the test, it can be discharged without affecting the environment and air.

[0026] A liquid collecting bucket 11 is fixedly connected to the inside of the deodorizing reaction box 1, an air inlet is provided at the top of the liquid collecting bucket 11, a water retaining top 12 is fixedly connected to the top of the liquid collecting bucket 11, the liquid collecting bucket 11 is located at the top of the sewage reaction chamber 5, a spray chamber 18 is arranged above the sewage reaction chamber 5 inside the deodorizing reaction box 1, the liquid collecting bucket 11 isolates and segments the sewage reaction chamber 5 from the spray chamber 18, an exhaust pipe 17 is fixedly connected to the top of the deodorizing reaction box 1, and the exhaust pipe 17 and the spray chamber 18 are communicated with each other.

[0027] When the sewage is discharged, the reacted gas will rise layer by layer through the air inlet at the top of the liquid collecting bucket 11 and enter the interior of the spray chamber 18 for collection and treatment. The interior of the spray chamber 18 is injected with disinfectant below the air inlet at the top of the liquid collecting bucket 11.

[0028] A disinfectant water pump 13 is fixedly installed on one side of the liquid collecting bucket 11, and a disinfectant water pipe 14 is fixedly connected to the top of the disinfectant water pump 13. The disinfectant water pipe 14 is in a circular shape, and a plurality of atomizing nozzles 15 are fixedly connected to the surface of the disinfectant water pipe 14. The plurality of atomizing nozzles 15 are equidistantly arranged on the surface of the disinfectant water pipe 14 in a circular array.

[0029] When the gas after the reaction enters the spray chamber 18, the disinfection water pump 13 on the side of the liquid collecting bucket 11 is started to pump the disinfectant. The disinfectant enters the disinfection water pipe 14 through the pumping of the disinfection water pump 13. The disinfectant inside the disinfection water pipe 14 is atomized by the atomizing nozzle 15 to disinfect the gas. The water retaining top 12 on the top of the liquid collecting bucket 11 blocks the sprayed gas to prevent the disinfectant from entering the sewage reaction chamber 5 through the air inlet of the liquid collecting bucket 11 and mixing with the treated sewage. After the disinfectant is sprayed, it reaches the emission standard and is discharged through the exhaust pipe 17, which can avoid the impact of the post-reaction gas emission on the environment. The disinfectant inside the spray chamber 18 will be gathered to the disinfection water pump 13 due to the special shape of the liquid collecting bucket 11 for repeated reflux and use, thereby reducing the waste of disinfectant.

[0030] Working principle:

[0031] When deodorizing the purified sewage, it is necessary to inject the sewage from the sewage injection pipe 4 into the interior of the deodorization reaction box 1 to fill the sewage reaction chamber 5. When the sewage injection pipe 4 is filled, the ozone injection pipe 6 simultaneously injects ozone into the sewage reaction chamber 5. At this time, the motor 3 starts its output shaft to drive the stirring blade 7 to rotate between each layer of the stratified baffle 9. When the stirring blade 7 rotates, the spoiler groove 8 rotates synchronously to fully contact and mix the ozone with the sewage. When the sewage passes through the adsorption filter 10 set on the stratified baffle 9, it will be purified and adsorbed by its characteristics. The ozone passes through the ozone injection pipe 6 inside the sewage reaction chamber 5 and evenly contacts and reacts with the injected sewage to produce a reaction.

[0032] After purification, the sewage will be discharged through the drain pipe 16 above the stratified baffle 9 for testing. It can be discharged after passing the test. When the sewage is discharged, the reacted gas will rise layer by layer and pass through the air inlet at the top of the liquid collecting bucket 11 to enter the spray chamber 18 for collection and treatment. The spray chamber 18 is injected with disinfectant below the air inlet at the top of the liquid collecting bucket 11. The disinfection water pump 13 on one side of the liquid collecting bucket 11 is started to pump the disinfectant. The disinfectant enters the disinfection water pipe 14 through the pumping of the disinfection water pump 13. The disinfectant in the disinfection water pipe 14 is atomized by the atomizing nozzle 15 to disinfect the gas. The water retaining top 12 on the top of the liquid collecting bucket 11 blocks the sprayed gas to prevent the disinfectant from entering the sewage reaction chamber 5 through the air inlet of the liquid collecting bucket 11 and mixing with the treated sewage. After being sprayed with disinfectant, it reaches the discharge standard and is discharged through the exhaust pipe 17.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
