Description

Technical Field

[0001] This utility model relates to the field of phosphorus removal technology, specifically to a high-efficiency integrated post-phosphorus removal device. Background Technology

[0002] In the context of rapid industrial development, numerous enterprises generate large amounts of industrial wastewater during production, much of which contains high concentrations of phosphorus. Phosphorus, a common pollutant, if discharged directly into the environment without effective treatment, not only causes eutrophication of water bodies, leading to excessive algal blooms, consuming oxygen, and affecting the survival of other aquatic organisms, but also disrupts the aquatic ecological balance, posing a serious threat to human health and the ecological environment. With increasing national awareness of environmental protection and increasingly stringent environmental regulations, higher standards have been set for phosphorus discharge into industrial wastewater. However, many enterprises' existing wastewater treatment plants, either not adequately designed with phosphorus removal needs in mind or employing outdated technologies, are unable to meet current stringent phosphorus removal standards.

[0003] In common phosphorus removal methods, wastewater needs to be mixed with phosphorus removal agents. However, the common mixing method is stirring, which makes it difficult to mix suspended solids in wastewater with phosphorus removal agents. Therefore, a highly efficient integrated post-phosphorus removal device is proposed. Utility Model Content

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a highly efficient integrated post-phosphorus removal device, which has the following beneficial effects:

[0020] This invention introduces wastewater into the coagulation zone through an inlet pipe, activates the stirring and aeration structures within the coagulation zone, and uses a feeding pipe to add phosphorus removal agent into the mesh cage. A servo electric cylinder controls the mesh cage to reciprocate up and down, swaying. Through the swaying of the mesh cage, combined with the stirring and aeration, the dissolution and dispersion of the agent in the wastewater are accelerated, improving mixing efficiency and ensuring thorough mixing of the phosphorus removal agent. The up-and-down swaying of the mesh cage increases the contact area between the agent and the wastewater, promoting the dissolution and dispersion of the agent and ensuring contact mixing between suspended solids in the wastewater and the phosphorus removal agent, thus solving the problems mentioned in the background art.

[0026] This utility model provides a technical solution: a high-efficiency integrated post-phosphorus removal device. Please refer to [link / reference needed]. Figure 1 , Figure 2 and Figure 3 ,include:

[0027] The coagulation zone 2, water distribution zone 7, filling zone 4 and sludge storage zone 10, with a top frame 13 fixedly installed at the upper part of the interior of the coagulation zone 2;

[0028] Feeding pipe 14 is located in the middle of the top frame 13 and is slidably connected to the top frame 13. A wire mesh 16 is fixedly installed at the lower end of the feeding pipe 14.

[0029] The servo electric cylinder 15 is fixedly installed on one side of the lower end of the top frame 13, and the output end of the servo electric cylinder 15 is fixed to the feeding pipe 14.

[0030] A drive motor 11 is located at the lower end of the interior of the coagulation zone 2, and a stirring rack 12 is fixedly installed at the output end of the drive motor 11.

[0031] Aeration pipe 17 is installed on both sides inside the coagulation zone 2.

[0032] Please see Figure 1 , Figure 2 and Figure 3 The drive motor 11 is fixedly connected to the coagulation zone 2, and the aeration pipe 17 is fixedly connected to the coagulation zone 2. The drive motor 11 is used to control the rotation of the stirring rack 12.

[0033] Please see Figure 1 and Figure 2 A water inlet pipe 1 is fixedly installed on the outer side of the coagulation zone 2, and a water distribution pipe 3 is provided on the inner side of the coagulation zone 2 away from the water inlet pipe 1, and the water distribution pipe 3 extends into the interior of the water distribution zone 7.

[0034] Please see Figure 1 and Figure 2 An overflow trough 5 is fixedly installed at the upper part of the inner side of the filling area 4, and an outlet pipe 6 is fixedly installed at one end of the outer side of the overflow trough 5.

[0035] Please see Figure 1 and Figure 2The sludge storage area 10 is located below the water distribution area 7. A sludge discharge pipe 8 is fixedly installed on the lower exterior of the sludge storage area 10. The sludge discharge pipe 8 is used to discharge sludge.

[0036] Please see Figure 1 and Figure 2 A sludge scraper 9 is provided on the left side of the sludge storage area 10. The sludge scraper 9 is used to scrape phosphorus-containing sludge into the sludge storage area 10.

[0037] This solution involves connecting the input end of aeration pipe 17 to an aerator. Wastewater from the original wastewater treatment plant enters the integrated phosphorus removal device via the lift inlet pipe 1. After entering the integrated equipment, the wastewater first enters the coagulation zone 2. In the coagulation zone 2, the drive motor 11 is activated to agitate the wastewater using the mixing frame 12. Aeration is then achieved by starting the aerator and using aeration pipe 17. Phosphorus removal agent is added to the feeding pipe 14, and the servo cylinder 15 is activated. The servo cylinder 15 drives the feeding pipe 14 and the mesh cage 16 to reciprocate upward and downward movements. The mesh cage 16 restricts and shakes the movement. The combination of stirring and aeration can accelerate the dissolution and dispersion of the agent in the wastewater, improve the mixing efficiency, and ensure that the phosphorus removal agent is fully mixed. The up-and-down shaking of the mesh cage 16 can increase the contact area between the agent and the wastewater, promote the dissolution and dispersion of the agent. The wastewater in the coagulation zone 2 enters the distribution zone 7 through the distribution pipe 3, and enters the phosphorus removal stage evenly through the distribution. After being treated in the packing zone 4, the effluent is discharged through the overflow trough 5 and the effluent pipe 6. The phosphorus-containing sludge enters the sludge storage zone 10 through the scraper 9, and the sludge is discharged through the sludge discharge pipe 8.
