Description

Technical Field

[0001] The utility model relates to the technical field of sewage recycling and treatment, in particular to sewage recycling and treatment equipment. Background Art

[0002] In order to reduce the waste of water resources and prevent sewage from being directly discharged and polluting water bodies, domestic sewage or factory sewage is usually purified and then recycled for secondary use. During the sewage recycling process, it is necessary to use sewage recycling and treatment equipment in the sewage treatment plant to filter and remove harmful substances from the sewage multiple times. The silt in the sewage is filtered through the filtering equipment, and the impurities in the sewage are condensed into flocs by adding chemicals for impurity removal. The harmful substances in the water are further reduced by exposure to the sun before the sewage can be recycled.

[0003] The existing utility model with authorization announcement number CN221235334U discloses a sewage treatment and recovery device including a filter box, which is fixedly connected to one side above the recovery device body, a water inlet, which is fixedly connected to the top of the filter box, and the sewage is poured into the filter box from the annular water inlet, and a filtering mechanism, which is fixedly connected to the top of the recovery device body.

[0004] By adopting the above technical solution, the purpose of adsorbing and collecting impurities and metals in sewage is achieved through the filter layer and the magnetic plate. The magnetic plate will adsorb the metal ions in the sewage during the stirring process, which can prevent the discharged sewage from posing a risk of heavy metal pollution to the environment, and the adsorbed metals can also be recycled. However, in the above technical solution, when the sewage treatment plant's sewage recovery and treatment equipment treats sewage, a large amount of waste gas generated by the sewage cannot be better treated, but is directly discharged to the outside. The waste gas generated by the sewage contains a large amount of bacteria and other organic matter, which will pollute the surrounding air, resulting in poor air quality around the sewage treatment plant and a heavy odor, which greatly affects the environmental friendliness of the sewage treatment plant's sewage recovery and treatment equipment when it is used.

[0005] Therefore, those skilled in the art provide a sewage recycling and treatment device to solve the problems raised in the above background technology. Utility Model Content

The fixing plate 8 can fix the position of the first exhaust fan 304 inside the connecting tube 303, so that the first exhaust fan 304 can operate stably.

[0029] In some preferred embodiments, the upper surface of the fixed frame 302 is fixedly connected to the connecting frame 308, the connecting frame 308 is communicated with the fixed frame 302, the inner wall of the connecting frame 308 is fixedly connected to the electrostatic generator 309, and a plurality of electrode rods 310 are arranged on the left side of the electrostatic generator 309. The bottom end of each electrode rod 310 is fixedly connected to the inner bottom wall of the connecting frame 308. The left side of the connecting frame 308 is hinged with a sealing door 9 through a hinge, and the left side of the sealing door 9 is fixedly connected to a handle 10. Manually pulling the handle 10 to cooperate with the sealing door 9 can facilitate the staff to open the connecting frame 308 and inspect the internal equipment of the connecting frame 308.

[0030] In other preferred embodiments, the right side of the fixing frame 302 is fixedly connected to the filter box 311, and the upper surface of the filter box 311 is fixedly connected to the connecting pipe 312. The end of the connecting pipe 312 away from the filter box 311 passes through the connecting frame 308 and extends to the left side of the electrode rod 310. Two activated carbon filter plates 313 are clamped inside the filter box 311.

[0032] When the utility model is in use, the first exhaust fan 304, the electric heating rod 306, the electrostatic generator 309, the electrode rod 310 and the suction pump 314 are first connected to the power supply. The suction provided by the first exhaust fan 304 cooperates with the connecting tube 303 and the shielding shed 2 to suck the waste gas generated by the sewage in the sedimentation tank 1 into the fixed frame 302. After the waste gas enters the fixed frame 302, the high temperature generated by the heating frame 305 and the electric heating rod 306 can quickly heat the organic matter in the waste gas to carbonization, and the high temperature can also quickly decompose the odor molecules in the waste gas, and heat the sulfide, one of the main sources of the odor, to generate hydrogen sulfide, thereby reducing the odor in the waste gas.

[0033] After the waste gas has been heated and treated, it flows to the right inside the fixed frame 302 and contacts the baffle 307. A part of it is blocked and contacts the electric heating rod 306 again to be heated, thereby increasing the heating treatment effect of the waste gas, while part of the waste gas passes through the fixed frame 302 and enters the connecting frame 308. When the waste gas passes through the electrostatic generator 309, the high-voltage static electricity generated by the electrostatic generator 309 will make the dust particles in the waste gas carry negative charges, and then when the waste gas contacts the positive charge on the electrode rod 310, it will be adsorbed on the electrode rod 310. At this time, odor molecules such as phenol, formaldehyde and acetone in the waste gas will also be adsorbed on the electrode rod 310, further removing the odor in the sewage.

[0034] Finally, the suction force provided by the suction pump 314 cooperates with the filter box 311 and the connecting pipe 312 to suck the waste gas treated inside the connecting frame 308 into the filter box 311 for final impurity filtration and adsorption by the activated carbon filter plate 313, and finally discharges odorless clean air to the outside through the air guide pipe 315 and the exhaust pipe 316, so that the sewage treatment equipment of the sewage treatment plant cooperates with the deodorization mechanism 3, which can effectively remove the odor in the sewage recovery and treatment waste gas, reduce the pollution when the sewage recovery and treatment waste gas is discharged, and greatly increase the environmental friendliness of the sewage treatment equipment of the sewage treatment plant. Through the power provided by the air guide pipe 315 and the suction pump 314, a part of the filtered gas can be sent into the sewage in the sedimentation tank 1 through the air supply pipe 317 and the air outlet pipe 318, forming a boiling phenomenon in the sewage, so that the odor in the sewage can be better dissipated and treated, further reducing the odor content in the sewage, so that too much odor will not be emitted during the subsequent treatment of the sewage.
