Description

Technical Field

[0001] This utility model relates to the field of domestic sewage treatment technology, and in particular to a domestic sewage recycling treatment device based on biological treatment. Background Technology

[0002] Domestic sewage, mainly including kitchen washing water, toilet flushing wastewater, and other domestic wastewater, contains a large amount of suspended solids, chemically or biodegradable dissolved or colloidal organic matter, etc. If discharged directly without treatment, it will cause serious environmental pollution. Therefore, the treatment of domestic sewage has become an important issue in the field of environmental protection.

[0003] Traditional wastewater treatment methods often employ physical, chemical, or a combination of both, but these methods frequently suffer from low treatment efficiency, high energy consumption, and complex operation and maintenance. In recent years, with the continuous development of biotechnology, biological treatment methods have been widely used in domestic wastewater treatment due to their advantages such as high efficiency, energy saving, and environmental friendliness.

[0004] In the process of treating domestic wastewater using microorganisms, the conventional approach is to introduce the wastewater into a pool, then add microbial materials to contact the wastewater, thereby purifying it. However, a common problem is that the added microbial materials are mainly concentrated in one area of ​​the pool, resulting in relatively less contact between the wastewater and the microorganisms in other areas, leading to poor contact efficiency. This situation limits the effective treatment of pollutants by the microorganisms, thus affecting the overall purification efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a biological-based wastewater recycling treatment device. Through the combination of a reciprocating mechanism, a feeding mechanism, and an aeration mechanism, the feeding box can periodically change position, ensuring that the material evenly covers different areas of the treatment tank while simultaneously providing comprehensive aeration. This design not only improves treatment efficiency but also avoids localized over-treatment or under-treatment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A biological treatment-based domestic sewage recycling device includes a treatment tank, a feeding box is provided above the treatment tank, and a feeding mechanism for uniformly feeding materials is provided inside the feeding box.

[0008] Four mounting plates are fixedly installed at the upper end of the treatment tank, and a reciprocating mechanism for the reciprocating motion of the feeding box is provided between two of the mounting plates.

[0009] The side wall of the feeding box is equipped with an aeration mechanism for sewage tumbling.

[0010] Preferably, the feeding mechanism includes a uniform plate rotatably connected to the inner side of the feeding box, a gear rotatably connected to the side wall of the feeding box, the gear being coaxially fixed with the uniform plate, and a toothed plate fixedly installed at the upper end of the treatment tank, the toothed plate meshing with the gear.

[0011] Preferably, the reciprocating mechanism includes a reciprocating screw rotatably connected between two mounting plates, wherein a drive motor is fixedly mounted on the side wall of one of the mounting plates, the drive motor is coaxially fixed with the reciprocating screw, a screw nut is threaded onto the reciprocating screw, and the screw nut is fixedly connected to the feeding box.

[0012] Preferably, a slide rod is fixedly installed between the two mounting plates on the side away from the reciprocating screw, and a sliding sleeve is slidably connected to the slide rod, and the sliding sleeve is fixedly connected to the feeding box.

[0013] Preferably, the uniform material plate is composed of a rod and a plurality of rectangular plates arranged at equal intervals.

[0014] Preferably, the aeration mechanism includes an air pump fixedly installed on the side wall of the feeding box, a connecting plate fixedly installed on the side wall of the feeding box, the air pump communicating with the connecting plate, a plurality of air supply pipes fixedly installed at equal intervals at the lower end of the connecting plate, and a nozzle fixedly installed at the other end of the air supply pipe.

[0015] This utility model has the following beneficial effects:

[0016] The designed feeding mechanism, particularly the rotation of the equalizing plate and the meshing of gears and toothed plates, ensures uniform material feeding and distribution within the treatment tank. This not only improves the efficiency of biological treatment but also ensures the stability and consistency of the treatment results.

[0017] The aeration system, including an air pump, connecting plate, air supply pipe, and nozzles, effectively promotes wastewater turbulence and increases dissolved oxygen. The release of microbubbles not only enhances the wastewater's oxidation capacity but also promotes microbial growth and activity, thereby accelerating the decomposition and purification of organic matter in the wastewater.

[0018] The reciprocating mechanism allows the feeding box to periodically change position, ensuring that the material evenly covers different areas of the treatment tank while also providing comprehensive aeration. This design not only improves treatment efficiency but also avoids localized over- or under-treatment, thus achieving energy conservation and consumption reduction. Attached Figure Description

[0026] Reference Figures 1-3A biological wastewater recycling treatment device includes a treatment tank 1. A feeding box 5 is installed above the treatment tank 1 to hold and uniformly feed the materials required for biological treatment. The feeding box 5 is equipped with a feeding mechanism for uniformly feeding the materials. This mechanism ensures that the materials enter the treatment tank 1 stably and continuously through precise control, thereby optimizing the biological treatment efficiency. The feeding mechanism includes a uniform feeding plate 15 rotatably connected to the inner side of the feeding box 5. The uniform feeding plate 15 is composed of a rod and multiple rectangular plates arranged at equal intervals. A gear 9 is rotatably connected to the side wall of the feeding box 5. The gear 9 is coaxially fixed with the uniform feeding plate 15. The rotation of the gear 9 drives the uniform feeding plate 15 to rotate, further promoting the uniform mixing of materials. A toothed plate 7 is fixedly installed at the upper end of the treatment tank 1. The toothed plate 7 meshes with the gear 9.

[0027] Four mounting plates 2 are fixedly installed on the upper end of the treatment tank 1. A reciprocating mechanism for the reciprocating motion of the feeding box 5 is set between two mounting plates 2. By periodically changing the position of the feeding box 5, it is ensured that the material can evenly cover different areas of the treatment tank 1. The reciprocating mechanism includes a reciprocating screw 4 rotatably connected between two mounting plates 2. A drive motor 3 is fixedly installed on the side wall of one of the mounting plates 2. The drive motor 3 is coaxially fixed with the reciprocating screw 4. A screw nut 6 is threadedly connected to the reciprocating screw 4. The screw nut 6 is fixedly connected to the feeding box 5.

[0028] A slide rod 10 is fixedly installed between two mounting plates 2 on the side away from the reciprocating screw 4 to provide additional stability and guidance. A sliding sleeve 8 is slidably connected to the slide rod 10. The sliding sleeve 8 is fixedly connected to the feeding box 5 to ensure the stability of the feeding box 5 during the reciprocating motion.

[0029] The side wall of the feeding box 5 is equipped with an aeration mechanism for sewage tumbling. The aeration mechanism includes an air pump 12 fixedly installed on the side wall of the feeding box 5. A connecting plate 14 is fixedly installed on the side wall of the feeding box 5. The air pump 12 is connected to the connecting plate 14. Multiple air supply pipes 11 are fixedly installed at equal intervals at the lower end of the connecting plate 14. The other end of the air supply pipes 11 is fixedly installed with nozzles 13. These nozzles 13 release gas into the sewage in the form of microbubbles, promoting sewage tumbling and increasing dissolved oxygen, thereby accelerating the biological treatment process.

[0030] Working principle:

[0031] When the device starts working, the drive motor 3 starts, driving the reciprocating screw 4, which is fixed coaxially with it, to rotate. The rotation of the reciprocating screw 4 causes the screw nut 6, which is threaded to it, to move along its axis, thereby driving the feeding box 5 to reciprocate between the two mounting plates 2. At the same time, the movement of the feeding box 5 is stabilized by the sliding sleeve 8 on the slide rod 10.

[0032] Meanwhile, as gear 9 meshes with gear plate 7, as feeding box 5 moves, gear 9 rotates, which in turn drives uniform plate 15, which is fixed coaxially with gear 9, to rotate. The rotation of uniform plate 15 can ensure that the material is evenly distributed in feeding box 5 and is uniformly fed into treatment tank 1 through the opening at the bottom of feeding box 5.

[0033] During the reciprocating motion of the feeding box 5, after the air pump 12 starts, it supplies air to multiple air pipes 11 through the connecting plate 14, and finally releases the gas into the sewage in the treatment tank 1 in the form of tiny bubbles through the nozzle 13. As these bubbles rise, they cause the surrounding sewage to tumble, increasing the dissolved oxygen content in the sewage, promoting the growth and activity of microorganisms, thereby accelerating the decomposition and purification process of organic matter in the sewage.
