Description

Technical Field

[0001] The utility model relates to the technical field of sewage deodorization, in particular to a sewage odor treatment system. Background Art

[0002] Some open wastewater pools within sewage treatment plants produce a large amount of odorous gases, affecting the normal production and living needs of plant workers and surrounding residents. To reduce the harm caused by odor, the wastewater pools need to be sealed and measures must be taken to collect and treat the odor. When treating the odor, it is necessary to adjust the proportion of deodorizers to effectively remove the odor. Different levels of odor require different ratios of deodorizers for effective deodorization.

[0003] Patent No. 202222118664.0 discloses a spray deodorizing device with automatic proportioning function, which includes a mixing tank, a proportioning component is provided on one side of the mixing tank, and stirring components are provided on both sides of the inner cavity of the mixing tank; an appropriate amount of water needs to be manually added to the mixing tank, and then the corresponding medicine is added to the storage bin of the proportioning component. When the isolation plate rotates, the medicine in the storage bin enters the mixing tank, and the medicine in the storage bin and the water in the mixing tank need to be manually measured and poured, which is very cumbersome, and an isolation plate is also required in the storage bin to rotate to push the medicine from the storage bin into the mixing tank. At the same time, a stirring element is also required in the mixing tank for sufficient mixing. The rotation of the isolation plate and the stirring element need to be driven by a power device, the structure is complex, and the cost of use is increased.

[0004] Currently, when using deodorants for deodorization, it is necessary to spray through a spray nozzle. At the same time, there are multiple filter layers in the absorption tower with high density. A fan is needed to extract air to remove the filtered odor. This requires multiple layers of filtration, which increases the deodorization cost and is not convenient to assemble.

[0005] Before the odor is treated, there will be floating flocs and other pollutants in the sewage, which will affect the purification efficiency during deodorization and purification. After the reaction in the wastewater pool, they will also accumulate in the wastewater pool and clog the pipes and require manual cleaning. Therefore, solid-liquid separation is required to package the solid phase for composting and the liquid phase flows into the collection tank. At present, solid-liquid separation generally uses the activated sludge method, which directly introduces the sewage into the aeration tank and then into the sedimentation tank. The biological coagulation, adsorption and oxidation of the activated sludge are used to decompose and remove organic pollutants in the sewage, and then the sludge is separated from the water. The process is cumbersome and cannot provide preliminary treatment of the sewage, and the odor cannot be eliminated in time. Utility Model Content

After the quantitative sewage is transported, the exhaust pipe 11 is opened synchronously to exhaust air, and the rotating motor drives the active wheel 37 to rotate and drive the driven wheel 38 to rotate, so that the drive shaft 5 rotates and drives the drum 6 to rotate, centrifugally throw out the sewage, and the flocculants remain in the filter bag 8. Then, after stopping the rotation, the flushing pipe 30 flushes the conical surface of the conical protrusion 13, and the drum 6 continues to rotate. After flushing, the excess sewage is centrifugally thrown out and the sewage is discharged from the liquid outlet 12. The top driving motor 26 drives the power driving wheel 25 to rotate, and the belt The dynamic pushing driving wheel 24 rotates on the pushing platform 23, and the pushing rod 9 rises and falls to lift the filter bag 8.

The water tank rotating motor 63 drives the water tank driving rod 62 to rotate, driving the water tank turntable 61 to rotate, causing the water tank lifting rod 60 to spirally descend, and when it contacts the water tank blocking bolt 68, it stops descending. Then, medicine and water are added to the medicine box body 41 and the water tank body 42 from the medicine adding port 49 and the water adding port 51. The excess medicine and water will be discharged from the overflow port 50 and the overflow port 52. Then, the addition of medicine and water is stopped, and the solenoid valve 53 of the connecting pipe 44 is opened. The medicine and water enter the mixing box 43, and then the air pump 71 blows air into the aeration pipe 70. , the deodorant and water entering are mixed, the drainage pump 92 extracts the deodorant in the mixing box 43 through the drainage pipe 45, enters the deodorant liquid inlet pipe 79, and sprays the deodorant from the spray nozzle 78. The odor enters the deodorizing cylinder 75 through the air inlet pipe 72, and then the deodorant and odor are gathered on the blocking plate 80, and then leak downward from the upper through hole 82, and then slowly descend on the spiral surface 86. At the same time, the deodorant will also fall from the lower through hole 87 with part of the odor, and finally enter the main drain pipe 73 and be discharged into the return liquid pool 91. The purified odor is slowly discharged from the vent 94; the main extraction pump 103 extracts the sewage and deodorant in the odor tank and the return liquid pool 91 through the processing pipeline 99 for subsequent treatment.
