[0002] As people's environmental awareness gradually increases, the government has set higher requirements for wastewater discharge standards for domestic sewage treatment plants and industrial park wastewater treatment plants. However, due to the low C / N ratio of domestic sewage and industrial wastewater in my country, large amounts of external carbon sources must be added to the wastewater treatment ponds to ensure that the total nitrogen in the effluent meets discharge standards.

[0003] A search revealed a Chinese utility model patent for a carbon source dosing device (publication number: CN 220579040 U). This carbon source dosing device uses a dispersion cylinder and a stirring dispersion component at the end of the carbon source output to agitate the output carbon source, thereby enabling the carbon source to be quickly and evenly dispersed into the wastewater and preventing carbon source concentration in the wastewater. However, it still has shortcomings. It is inconvenient to add carbon source at different locations in the wastewater tank, which can easily cause local overdose. This not only leads to low microbial utilization efficiency, but in severe cases, it can also induce filamentous bacteria bulking and damage sludge settling properties.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the internal structure of the storage tank in this utility model; Figure 3 This is a schematic diagram of the dispersion drive mechanism in this utility model. It includes: a storage tank 1, an anti-deposition mechanism, a dosing mechanism, and a dispersion drive mechanism.

[0022] refer to Figure 1 and Figure 3As shown, the upper surface of the storage tank 1 is fixedly connected to a feed pipe 3, and the upper end of the feed pipe 3 is threadedly connected to a matching cover. The lower surface of the storage tank 1 is fixedly connected to multiple evenly distributed support columns 2. An anti-settling mechanism is connected inside the storage tank 1. A dosing mechanism is connected to the side of the storage tank 1. The dosing mechanism includes a suction pump 6, a liquid suction pipe 7, a liquid delivery pipe 8, a flexible hose 9, a dispersion cylinder 10, a foam float 18, and a partition 13. The suction pump 6 is installed on the side of the storage tank 1. The inlet of the suction pump 6 is fixedly connected to the side of the storage tank 1 through the liquid suction pipe 7. The outlet of the suction pump 6 is fixedly connected to the liquid delivery pipe 8. The other end of the liquid delivery pipe 8 is fixedly connected to two symmetrically arranged flexible hoses 9 through a three-way pipe joint. The other end of the flexible hoses 9 is fixedly connected to the dispersion cylinder 10. Two symmetrically arranged partitions 13 are fixedly connected inside the dispersion cylinder 10. A foam float 18 is fixedly connected to the upper surface of the dispersion cylinder 10.

[0023] It should be noted that during use, the dispersion cylinder 10 is placed in the sewage. Due to the buoyancy of the foam float plate 18, the dispersion cylinder 10 can float in the water. Then, the suction pump 6 is used to pump the carbon source in the storage tank 1 into the dispersion cylinder 10 through the suction pipe 7, the delivery pipe 8 and the hose 9, thereby introducing the carbon source into the sewage.

[0024] refer to Figure 3 As shown, a dispersion drive mechanism is connected inside the dispersion cylinder 10. The dispersion drive mechanism includes a submersible dual-shaft motor 14, a rotating shaft 15, dispersion blades 16, and paddles 17. The submersible dual-shaft motor 14 is installed between two partitions 13. Both output ends of the submersible dual-shaft motor 14 pass through the adjacent partitions 13 and are fixedly connected to the rotating shaft 15 through a coupling. The other end of the rotating shaft 15 passes through the side of the rotating shaft 15. Multiple evenly distributed dispersion blades 16 are fixedly connected to the end of the rotating shaft 15 inside the dispersion cylinder 10, and multiple evenly distributed paddles 17 are fixedly connected to the end of the rotating shaft 15 outside the dispersion cylinder 10.

[0025] It should be noted that during the carbon source addition process, the submersible dual-shaft motor 14 is started, which drives the rotation of the rotating shaft 15. The rotation of the rotating shaft 15 drives the dispersing blades 16 to rotate, which in turn stirs the carbon source introduced into the dispersing cylinder 10, allowing the carbon source to be quickly dispersed to the surrounding sewage. In addition, the rotation of the rotating shaft 15 can drive the rotation of the paddle 17, which moves the paddle 17 in the sewage, causing the dispersing cylinder 10 to move in the sewage.

[0026] refer to Figure 1 and Figure 2As shown, the anti-deposition mechanism includes a drive motor 5, a stirring shaft 11, and stirring rods 12. The drive motor 5 is installed on the upper surface of the storage tank 1. The output end of the drive motor 5 passes through the upper surface of the storage tank 1 and is fixedly connected to the stirring shaft 11. Multiple evenly distributed stirring rods 12 are fixedly connected to the side of the stirring shaft 11.

[0027] It should be noted that during use, the drive motor 5 drives the rotation of the stirring shaft 11, and the rotation of the stirring shaft 11 drives the stirring rod 12 to stir the carbon source in the storage tank 1, so as to prevent the carbon source in the storage tank 1 from depositing.

[0028] refer to Figure 1 As shown, a drain pipe 4 is fixedly connected to the lower surface of the storage tank 1. A matching control valve is installed on the drain pipe 4. The carbon source in the storage tank 1 can be conveniently discharged through the drain pipe 4 and the control valve.

[0029] refer to Figure 1 and Figure 2 As shown, the lower end of the support column 2 is fixedly fitted with a matching anti-slip sleeve. The anti-slip sleeve increases the friction, making the support column 2 more stable when supported.

[0030] refer to Figure 1 As shown, a counterweight 19 is fixedly connected to the lower surface of the dispersion cylinder 10. Through the counterweight 19, the dispersion cylinder 10 is kept vertical by gravity, making it more stable during movement.

[0031] The working principle of this utility model is as follows: During use, the dispersion cylinder 10 is placed in sewage. Due to the buoyancy of the foam float plate 18, the dispersion cylinder 10 floats in the water. Then, the suction pump 6 draws the carbon source from the storage tank 1 into the dispersion cylinder 10 through the suction pipe 7, the delivery pipe 8, and the hose 9, thus introducing the carbon source into the sewage. During the carbon source introduction process, the submersible dual-shaft motor 14 is started. The submersible dual-shaft motor 14 drives the rotation of the rotating shaft 15, which in turn drives the dispersion blades 16 to rotate. This causes the dispersion blades 16 to stir the carbon source introduced into the dispersion cylinder 10, allowing the carbon source to be quickly dispersed to the surrounding area. The rotating shaft 15 drives the rotating blades 17 to move in the sewage, which in turn moves the dispersing cylinder 10 in the sewage. This allows the carbon source to be dispersed quickly and evenly in the sewage, preventing local over-dispersion of carbon source and improving the utilization efficiency of microorganisms. It also prevents damage to the sludge settling properties. During use, the driving motor 5 drives the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 drives the stirring rod 12 to stir the carbon source in the storage tank 1, preventing the carbon source in the storage tank 1 from settling. This makes the carbon source discharge more even.

[0032] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
