Technical Field
[0001] This utility model relates to the technical field of sewage treatment devices, specifically a sewage treatment device with a deodorization mechanism. Background Technology
[0002] Odor is an unavoidable problem in wastewater treatment plants. Its main source is the presence of large amounts of substances such as ammonia, nitrogen, and hydrogen sulfide in the wastewater, which has a significant impact on the air quality inside the plant and the surrounding living environment.
[0003] Wastewater deodorization processes are often placed in the last few steps of treatment. However, in the early sedimentation stage, open-air sedimentation tanks are the main source of odor. Currently, the main method is to continuously spray deodorizing mist to cover it up. However, this method consumes a lot of chemicals and water, and it cannot cover up the odor. In windy weather, the odor will still escape outward, so it does not have the function of removing odor and preventing escape.
[0004] Now, a novel wastewater treatment device with an odor removal mechanism is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a wastewater treatment device with a deodorization mechanism to solve the problem mentioned in the background art of not having the function of deodorization and preventing odor escape.

[0007] The deodorization assembly includes a fan fixedly connected to the left side of the top of the cover. A deodorization tank is fixedly connected to the middle of the top of the cover, and a solution tank is fixedly connected to the right side of the top of the cover. A return air duct is fixedly connected between the cover and the fan. An air supply duct is fixedly connected between the fan and the deodorization tank. An exhaust duct is fixedly connected between the cover and the deodorization tank. A spherical packing material is placed in the middle of the interior of the deodorization tank. A spray pipe is fixedly connected between the two sides of the interior of the deodorization tank. A three-way connector is fixedly connected to the bottom of the deodorization tank. A return pipe is fixedly connected between the three-way connector and the solution tank. A circulation pump is fixedly connected to the right side of the top of the solution tank. A water pumping pipe is fixedly connected between the solution tank and the circulation pump. A water supply pipe is fixedly connected between the spray pipe and the circulation pump. A sealing cap is threadedly connected to the left side of the top of the solution tank.
[0008] As a further technical solution of this utility model, the top cover, return air duct, and fan are internally connected, and the top cover, exhaust duct, and deodorizing tank are internally connected.
[0009] As a further technical solution of this utility model, the return air duct, supply air duct, and exhaust air duct have the same diameter, and the fan, supply air duct, and deodorization tank are internally connected.
[0010] As a further technical solution of this utility model, the bottom end of the spray pipe is higher than the top end of the spherical packing, and the controller, fan and circulating pump are electrically connected.
[0011] As a further technical solution of this utility model, a drain valve is fixedly connected to the bottom end of the three-way interface, the bottom end of the drain valve passes through the top cover and extends into the sedimentation tank, and the deodorizing tank, the three-way interface and the drain valve are internally connected.
[0012] As a further technical solution of this utility model, the top end of the return air duct is fixedly connected to an internally threaded pipe, and the front and rear ends of the internally threaded pipe are respectively provided with air outlet holes. A sealing threaded rod is vertically inserted into the top end of the internally threaded pipe, and a handwheel is fixedly connected to the top end of the sealing threaded rod. The internal threads of the internally threaded pipe and the external threads of the sealing threaded rod are matched, and the internal parts of the return air duct and the internally threaded pipe are connected.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the sewage treatment device with deodorization mechanism not only realizes the function of removing odor and preventing escape, but also realizes the function of easy replacement of reagents, and also realizes the function of easy pressure relief and exhaust.
[0014] (1) The system is equipped with a return air duct, a blower, an air supply duct, an exhaust duct, a deodorizing tank, spherical packing, a spray pipe, a tee connector, a drain valve, a solution tank, a circulating pump, a water pumping pipe, a water supply pipe, a sealing cover, and a return pipe. During use, wastewater enters the sedimentation tank through the inlet pipe and settles. The settled wastewater is discharged through the outlet pipe, and the sludge discharge pipe is used to discharge sludge. The odor emitted by the wastewater is masked by the top cover. Under the suction of the blower, the odor emitted by the wastewater in the sedimentation tank enters the deodorizing tank along the exhaust duct. The deodorizing agent solution in the solution tank is drawn by the circulation pump and sent to the spray pipe through the water supply pipe. The spray pipe sprays water mist downwards. The odorous gas passes through the spherical packing upwards, while the deodorizing agent passes downwards, making full contact with the odorous gas and neutralizing substances such as hydrogen sulfide in the odorous gas. The treated odorous gas flows back to the sedimentation tank through the return air pipe, forming an internal gas circulation. The solution inside the deodorizing tank flows back to the solution tank through the three-way interface and the return pipe, forming a solution circulation, thus achieving the function of removing odors and preventing escape.
[0015] (2) By setting up a drain valve and a sealing cover, when the solution in the solution tank has been used for a period of time, the concentration of the reagent inside decreases. Open the drain valve to drain part of the reagent into the sedimentation tank, and then open the sealing cover to replenish it, thus realizing the function of easy replacement of reagent.
[0016] (3) By setting up an internal threaded pipe, an air outlet, a sealing threaded rod and a handwheel, when there are fermentable substances in the sewage, the gas content in the sedimentation tank will increase continuously and the gas pressure will also increase. By periodically rotating the handwheel to raise the position of the sealing threaded rod, part of the gas in the return air pipe will rise along the internal threaded pipe and be discharged through the air outlet, reducing the internal pressure of the equipment and realizing the function of facilitating pressure relief and exhaust.

The top of the top cover 6 is provided with a deodorization component that can remove odors.
[0024] Please see Figure 1-4 A wastewater treatment device with a deodorization mechanism further includes a deodorization component, which includes a blower 8 fixedly connected to the left side of the top of a top cover 6. A deodorization tank 11 is fixedly connected to the middle of the top of the top of the top cover 6. A solution tank 16 is fixedly connected to the right side of the top of the top of the top cover 6. A return air duct 7 is fixedly connected between the top cover 6 and the blower 8. An air supply duct 9 is fixedly connected between the blower 8 and the deodorization tank 11. An exhaust duct 10 is fixedly connected between the top cover 6 and the deodorization tank 11.

[0025] The top cover 6, return air duct 7, and fan 8 are internally connected. The top cover 6, exhaust duct 10, and deodorizing tank 11 are internally connected. The return air duct 7, supply air duct 9, and exhaust duct 10 have the same pipe diameter. The fan 8, supply air duct 9, and deodorizing tank 11 are internally connected. The bottom end of the spray pipe 13 is higher than the top end of the spherical packing 12. The controller 2, fan 8, and circulating pump 17 are electrically connected. Odors can be isolated and treated through internal gas circulation.
[0026] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, under the suction of the blower 8, the odorous gas emitted from the sewage in the sedimentation tank 1 enters the deodorization tank 11 along the exhaust pipe 10. The deodorizing agent solution in the solution tank 16 is drawn by the circulation pump 17 and sent to the spray pipe 13 through the water supply pipe 19. The spray pipe 13 sprays water mist downwards. The odorous gas passes through the spherical packing 12 upwards, and the deodorizing agent downwards, making full contact with the odorous gas and neutralizing substances such as hydrogen sulfide in the odorous gas. The treated odorous gas flows back into the sedimentation tank 1 through the return air pipe 7, forming an internal gas circulation. The solution inside the deodorization tank 11 flows back into the solution tank 16 through the three-way interface 14 and the return pipe 21, forming a solution circulation. The controller 2, the blower 8, and the circulation pump 17 are electrically connected. This technology is existing technology and will not be described in detail.
[0027] A drain valve 15 is fixedly connected to the bottom of the three-way connector 14. The bottom of the drain valve 15 passes through the top cover 6 and extends into the sedimentation tank 1. The deodorizing tank 11, the three-way connector 14, and the drain valve 15 are connected internally, which facilitates the replacement of the solution.
[0028] Specifically, such as Figure 1 and Figure 2 As shown, open the drain valve 15 to drain part of the medicine into the sedimentation tank 1, and then open the sealing cover 20 to replenish it.
[0029] The top end of the return air duct 7 is fixedly connected to an internally threaded pipe 22. The front and rear ends of the internally threaded pipe 22 are respectively provided with air outlets 23. The top end of the internally threaded pipe 22 is vertically inserted with a sealing threaded rod 24. The top end of the sealing threaded rod 24 is fixedly connected to a handwheel 25. The internal threads of the internally threaded pipe 22 and the external threads of the sealing threaded rod 24 are matched. The internal parts of the return air duct 7 and the internally threaded pipe 22 are connected to facilitate exhaust and pressure relief.
[0030] Specifically, such as Figure 1 and Figure 3 As shown, by periodically rotating the handwheel 25, the position of the sealing threaded rod 24 is raised, and part of the gas in the return air pipe 7 rises along the internal threaded pipe 22 and is discharged through the air outlet 23, reducing the internal pressure of the equipment.
[0031] Working principle: In use, wastewater first enters the sedimentation tank 1 through the inlet pipe 5 and settles. The settled wastewater is discharged through the outlet pipe 3, and the sludge discharge pipe 4 is used to discharge sludge. The odor emitted by the wastewater is masked by the top cover 6. Under the suction of the blower 8, the odor emitted by the wastewater in the sedimentation tank 1 enters the deodorization tank 11 through the exhaust pipe 10. The deodorizing agent solution in the solution tank 16 is drawn by the circulation pump 17 and sent to the spray pipe 13 through the water delivery pipe 19. The spray pipe 13 sprays water mist downwards. The odor passes through the spherical packing 12 upwards, and the deodorizing agent downwards, making full contact with the odor and neutralizing substances such as hydrogen sulfide in the odor. The treated odor flows back into the sedimentation tank 1 through the return air pipe 7, forming an internal gas circulation. The solution inside the deodorization tank 11 flows back into the solution tank 16 through the three-way interface 14 and the return pipe 21, forming a solution circulation. After a period of use, the concentration of the reagent in the solution tank 16 decreases. The drain valve 15 is opened to partially drain the reagent into the sedimentation tank 1, and then the sealing cover 20 is opened to replenish it. When there are fermentable substances in the wastewater, the gas content in the sedimentation tank 1 continuously increases, and its pressure also increases. By periodically rotating the handwheel 25 to raise the position of the sealing threaded rod 24, some of the gas in the return air pipe 7 rises along the internal threaded pipe 22 and is discharged through the air outlet 23, reducing the internal pressure of the equipment.
