Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a device for removing green algae from the effluent channel of a secondary sedimentation tank. Background Technology

[0002] During wastewater treatment, due to the presence of certain influencing substances in the secondary sedimentation tank and the relatively stable conditions such as temperature and light, a large amount of algae often proliferates at the effluent weir (triangular weir) of the secondary sedimentation tank. If not cleaned in time, it will not only affect the stability and quality of the effluent, but also pose a significant threat to the stable operation of the secondary sedimentation tank.

[0003] Currently, algae removal or cleaning is generally carried out manually or by cleaning robots. Manual cleaning is labor-intensive, while existing cleaning robots are often only suitable for relatively large pools, such as round pools. They are often not applicable to other shapes, such as square pools, which greatly limits their use.

[0004] Therefore, this utility model proposes a device for removing algae from the effluent channel of a secondary sedimentation tank. It uses a combination of physical and chemical methods to fundamentally remove algae from the effluent channel, saving labor and being suitable for secondary sedimentation tanks of different shapes, making it more convenient for practical engineering applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a green algae removal device for the effluent channel of a secondary sedimentation tank, which is installed and arranged based on a secondary sedimentation tank. The secondary sedimentation tank consists of an outer wall, a partition wall, and a triangular weir from the outside to the inside. The inlet channel is between the outer wall and the partition wall, and the outlet channel is between the triangular weir and the partition wall. The triangular weir includes an inner wall, and the weir body is located on the front side above the inner wall. The inner wall has a slope behind the weir body.

The infusion pipe is arranged and installed at the triangular weir of the secondary sedimentation tank, and an atomizing nozzle is arranged and installed below the infusion pipe. The ultraviolet lamp is arranged and installed above the partition wall on the side near the outlet channel.

[0007] Furthermore, the infusion pipe is arranged around the secondary sedimentation tank, with one end of the infusion pipe closed and the other end connected to the delivery pump.

The pipe fastener includes a lower fastener, which is fixedly connected to the support rod. One side of the lower fastener is hinged to the upper fastener. The upper fastener and the lower fastener are fastened together by connecting bolts.

[0010] Furthermore, the ultraviolet lamp is installed and fixed by a mounting bracket, and a waterproof cover is provided on the outside of the ultraviolet lamp. The waterproof cover is installed and arranged by the mounting bracket.

[0011] Furthermore, the mounting bracket is fixedly connected to the partition wall, and the mounting bracket is provided with a UV lamp mating part and a waterproof cover mating part, the UV lamp mating part mating with the UV lamp; the mounting bracket mating part is provided on the inner side of the waterproof cover, the mounting bracket mating part mating with the waterproof cover mating part.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0024] Embodiments of this utility model:

[0025] like Figure 1-7 As shown, this embodiment is based on a circular secondary sedimentation tank 1. For the secondary sedimentation tank 1, from the inside to the outside of the tank body, there are an inlet channel 11, an outlet channel 13 and a triangular weir 12. The outer wall is located outside the inlet channel 11, and the inner wall 121 is located below the weir body 122 of the triangular weir 12. The inlet channel 11 and the outlet channel 13 are separated by a partition wall 111.

[0026] In this embodiment, an infusion pipe 2 is installed on the inner wall 121, and an atomizing nozzle 21 is installed below the infusion pipe 2. The infusion pipe 2 is connected to a delivery pump, and sodium hypochlorite solution is pumped into the infusion pipe 2 through the delivery pump. An ultraviolet lamp 3 is installed on the side of the partition wall 111 near the water outlet channel 13, and the water outlet channel 13 is disinfected by ultraviolet light through the ultraviolet lamp 3.

[0027] In this embodiment, the infusion tube 2 is installed on the slope 1211 above the inner wall 121 via a fixing bracket 4. A support rod 41 is fixedly installed on the slope 1211, and then a pipe fastener 42 is fixedly connected (welded, etc.) to the support rod 41. The pipe fastener 42 includes a lower fastener 421, which is fixedly connected to the support rod 41. One end of the lower fastener 421 is hinged to the upper fastener 422. The infusion tube 2 is fixed between the upper fastener 422 and the lower fastener 421. The upper fastener 422 and the lower fastener 421 are connected and fixed by a connecting bolt 423. In this embodiment, expansion bolts are pre-embedded on the slope 1211, and a threaded hole 411 is provided below the support rod 41. The support rod 41 is fixedly connected to the expansion bolt through the threaded hole 411.

[0028] In this embodiment, the ultraviolet lamp 3 is installed and fixed by the mounting bracket 5, which is installed and fixed on the side wall of the partition wall 111 near the water inlet channel 11. The mounting box of the ultraviolet lamp 3 is fixed on the mounting bracket 5, and the waterproof cover 6 is installed and fixed by the mounting bracket 5. Specifically, expansion bolts are pre-embedded in the partition wall 111, and the mounting bracket 5 is installed and fixed on the partition wall 111 by the expansion bolts and nuts. The mounting bracket 5 includes an ultraviolet lamp mating part 51 and a waterproof cover mating part 52. The ultraviolet lamp mating part 51 is connected to the ultraviolet lamp 3 by bolts. A mounting bracket mating part 61 is provided below the waterproof cover 6, and the mounting bracket mating part 61 is connected to the waterproof cover mating part 52 by bolts. The waterproof cover 6 is arc-shaped and fits against the partition wall 111. The waterproof covers 6 are sealed with sealant between each other and between the waterproof cover 6 and the partition wall 111.

[0029] The principle of this utility model is as follows:

[0030] When using this utility model, the infusion tube 2, the atomizing nozzle 21, the ultraviolet lamp 3, and the waterproof cover 6 are first installed and fixed.

[0031] Once installed, algae on both sides of the outlet channel 13 can be eliminated. During the process, chemical agents, such as sodium hypochlorite solution, are pumped into the infusion pipe 2 to achieve chemical elimination of algae. At the same time, ultraviolet lamps can be turned on to achieve physical elimination of algae, thereby fundamentally preventing the growth and reproduction of algae.

[0032] In this utility model, the waterproof cover 6 is made of transparent material, such as PP. The waterproof cover 6 ensures the stable use of the UV lamp 3. On the one hand, it prevents splashed water droplets and water vapor from affecting the stable use of the UV lamp 3. On the other hand, it also serves as a rainproof function, making the use more stable. In order to ensure the stability of use, in actual engineering, the UV lamp 3 is first connected in series to form a group, and then the groups are connected in parallel. This plays a positive role in ensuring the stability of use and subsequent inspection and maintenance.

[0033] In actual production, this invention does not require continuous operation; it only needs to be run periodically for a period of time, such as about 1 hour every 2-3 days, to achieve a good disinfection effect. It should be noted that the technical solution of this invention lists an embodiment for a circular secondary sedimentation tank, but it will be easy for those skilled in the art to understand that this invention is also applicable to secondary sedimentation tanks of other shapes, such as square ones, and they also fall within the protection scope of this invention.
