Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an integrated aerobic precipitation device. Background Art

[0002] In the wastewater treatment process, a common process step is to aerobically treat the wastewater first and then precipitate it, which is called aerobic precipitation in the industry. The implementation of this process step is generally achieved by separately building the pool bodies, such as building an aerobic pool and a sedimentation pool. The main disadvantage of this implementation method is that the pool bodies are built and cannot be moved, and each pool body is arranged in a horizontal direction, occupying a large area.

[0003] For this reason, some new combined tank bodies or systems have emerged in the field of wastewater treatment, such as combining sedimentation tanks, aeration tanks and reaction tanks, wherein the sedimentation tank is located between the aeration tank and the reaction tanks, and the sedimentation tanks share walls with the aeration tanks and the reaction tanks. Although the tank body or system of this structure saves time and cost compared to a single masonry tank body, the tank bodies are still arranged in a horizontal direction. Although the floor area is reduced, the effect is not outstanding.

[0004] Based on this, some vertical combined tanks or systems have appeared in the field of wastewater treatment. Although these tanks or systems have been set up in the vertical direction to solve the problem of floor space, the sedimentation tank is basically located above the aeration tank and is located at the top of the combined tank or system. In addition, the combined tank or system is set up vertically as a whole, which makes the water outlet height of the sedimentation tank very high. In this state, in order to introduce the very high effluent to the ground tank in the next process, a very long pipe is required for circulation, and in order to ensure the flow rate, multiple pipes are basically required. This will inevitably affect the simplicity of the peripheral structure of the combined tank or system. In addition, most combined tanks or systems are basically set up with other tanks except sedimentation tanks and aerobic tanks, which will inevitably make the overall structure complicated.

[0005] Based on the above-mentioned deficiencies, the present application mainly aims to apply for an integrated aerobic sedimentation equipment which is not mounted on the top of the sedimentation tank. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes an integrated aerobic sedimentation equipment with a new structure, which effectively solves the problem of insufficient reduction in floor space and complex overall structure through a vertical layout with a sedimentation tank at the bottom and an aerobic tank at the top.

The bottom of the cylinder body is provided with a bell mouth, which faces the center direction of the bottom of the sedimentation tank. The reflective plate is arranged below the bottom opening and connected to the bottom of the cylinder body through a connecting rod. The reflective plate is cone-shaped as a whole and the top of the cone faces the bell mouth.

[0009] Preferably, the first pipeline is composed of two tube bodies which are symmetrically arranged on both sides of the central reflective cylinder and are both connected to the central reflective cylinder along the tangent direction of the central reflective cylinder.

[0010] Preferably, a water distributor is provided near the bottom of the aerobic tank and above the aeration plate, and the main pipe of the water distributor is respectively connected to the external water inlet pipe and the return pipe, and the return pipe is connected to the bottom of the sedimentation tank through a water pump.

[0030] The following will be combined with the accompanying drawings to clearly describe the technical solutions in the specific embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the following embodiments are within the scope of protection of the utility model.

[0031] Based on optimizing the floor space, facilitating relocation, simplifying the structure, and meeting the requirements of aerobic and sedimentation process steps, the utility model provides an integrated aerobic sedimentation equipment with a new structure. The equipment is an integral structure with aerobic tanks and sedimentation tanks arranged vertically up and down, which not only meets the requirements of aerobic and sedimentation process steps, but also can be relocated, effectively reducing the floor space, and optimizing and improving the aerobic reaction and sedimentation effects.

[0032] The integrated aerobic sedimentation equipment is particularly suitable for the process of using activated sludge to treat wastewater. In this process, there are aerobic and sedimentation processes. Through the integrated aerobic sedimentation equipment of the utility model, the aerobic and sedimentation processes can be effectively carried out in the same equipment.

[0033] Specifically, the integrated aerobic precipitation equipment of the utility model is described in detail below.

[0034] refer to Figure 1-Figure 3 This embodiment discloses an integrated aerobic sedimentation equipment, which includes a tower body 1 made of metal material, the tower body is provided with a partition 2, the chamber of the tower body 1 above the partition 2 is configured as an aerobic pool 3, the chamber of the tower body 1 below the partition 2 is configured as a sedimentation pool 4, and the aerobic pool 3 and the sedimentation pool 4 are vertically arranged up and down. It should be noted that the tower body 1 is made of metal plates as a whole, and has a certain bearing strength. After the overall manufacturing and forming, it can be disassembled and moved, and when it is needed, it can be connected and assembled into the tower body 1. Under the premise that the tower body 1 is made of metal material, the integrated aerobic sedimentation equipment does not need to be built with a pool body. When the integrated aerobic sedimentation equipment is not needed, it can be disassembled and moved to avoid further occupying the land. In this embodiment, the aerobic tank 3 is on the top and the sedimentation tank 4 is on the bottom. Compared with the prior art in which the sedimentation tank is basically located at the top of the equipment or system, after the sedimentation tank 4 is arranged under the aerobic tank 3, the utility model can continue to meet the process steps of aerobic reaction and sedimentation.

[0035] In order to realize the aerobic reaction and precipitation process steps, the two tank bodies are interconnected. The bottom of the partition 2 is equipped with a central reflector 5 with an opening facing the sedimentation tank 4. The aerobic tank 3 is provided with a first water outlet weir 6. A first pipe 7 is connected between the first water outlet weir 6 and the central reflector 5. The first pipe 7 is connected to the central reflector 5 along the tangent direction of the central reflector 5. Therefore, the effluent after the aerobic reaction in the aerobic tank 3 can flow into the central reflector 5 through the first water outlet weir 6 and the first pipe 7. Since the first pipe 7 is connected to the tangent direction of the central reflector 5, the water flows downward along the inner wall of the central reflector 5 in a swirling downward posture. In addition, the central reflector 5 is not a conventional straight tube, and the following optimizations and improvements are also made:

[0036] The central reflector 5 comprises a cylinder 51 and a reflector plate 52. The bottom of the cylinder 51 is provided with a bell mouth 53, which faces the center direction of the bottom of the sedimentation tank 4. The reflector plate 52 is arranged below the bell mouth 53 and connected to the bottom of the cylinder 51 through a connecting rod 54. The reflector plate 52 is in a cone shape as a whole and the top of the cone faces the bell mouth 53. It can be seen that the central reflector 5 is provided with the bell mouth 53 and the reflector plate 52 opposite thereto, so that the water flow descending from the above-mentioned swirl can be ejected from the gap between the bell mouth and the reflector plate 52 to the side wall of the sedimentation tank 4 in an emission state, and the water flow is prevented from flowing directly vertically to the center of the bottom of the sedimentation tank 4, thereby effectively avoiding disturbance of the sediment at the bottom of the sedimentation tank 4, which is conducive to ensuring the sedimentation effect;

[0037] At the same time, the aerobic tank 3 is provided with an air intake main pipe 10 connected to an external blower. The air intake main pipe 10 is laid at the bottom of the aerobic tank 3 through a plurality of branch pipes 11. A plurality of aeration plates 12 are installed on the branch pipes 11. The aeration plates 12 are fully arranged at the bottom of the aerobic tank 3, so that the bottom of the aerobic tank 3 is completely covered with the aeration plates 12. In this way, during the aerobic reaction, the aeration through the fully arranged aeration plates 12 makes the aerobic reaction more sufficient.

[0038] After the aerobic tank 3 and the sedimentation tank 4 are vertically arranged up and down, the height position of the top of the sedimentation tank 4 is greatly reduced. At this time, the sedimentation tank 4 is also provided with a second water outlet weir 8, and the second water outlet weir 8 is connected with a second pipe 9 to connect the second water outlet weir 8 with the external tank body. It can be seen that after the height position of the second water outlet weir 8 is effectively greatly reduced, the setting length of the second pipe 9 can be greatly reduced, the external structure is simplified, and the height is reduced at the same time, which is more conducive to the installation and laying of the pipeline.

[0039] In this embodiment, some special optimizations and improvements are also made, such as: the first pipeline 7 is composed of two tubes that are symmetrically arranged on both sides of the central reflector 5, and the two tubes are symmetrically arranged on both sides of the central reflector 5 and are connected to the central reflector 5 along the tangent direction of the central reflector 5. It can be seen that the two tubes are symmetrically arranged outside the aerobic pool 3 to form a regular symmetry, and are also symmetrically arranged at the central reflector 5, which is more conducive to forming a strong and powerful vortex in the central reflector 5.

[0040] In order to realize the continuous recycling of the sediment in the sedimentation tank 4, a water distributor 13 is provided near the bottom of the aerobic tank 3 and above the aeration plate 12. The main pipe 131 of the water distributor 13 is respectively connected to the external water inlet pipe 14 and the return pipe 15. The return pipe 15 is connected to the bottom of the sedimentation tank 4 through the water pump 16. Specifically, the water distributor 13 includes a main pipe 131 and a plurality of water distribution pipes 132 arranged in parallel at the outlet end of the main pipe 131. The water distribution pipes 132 extend horizontally in the aerobic tank 3 in a radial shape as a whole. The water distribution pipes 132 are symmetrically distributed with the water distribution pipe in the middle as the reference. In actual use, after the sedimentation, such as activated sludge, at the bottom of the sedimentation tank 4 is precipitated, the water pump 16 can be used to dilute the sediment through the return pipe 15 and under the action of the external water inlet pipe 14, and then the sediment enters the water distributor 13. Through the water distributor 13, the return material is fully and evenly flowed into the aerobic tank 3 for uniform mixing, and under the aeration action of the aeration plate 12 below, an excellent aerobic reaction is achieved.

[0041] In this embodiment, the sedimentation tank 4 is also optimized and improved. Specifically, the sedimentation tank 4 has a cylindrical upper chamber 41 and a conical lower chamber 42, and a bracket 17 is provided at the bottom of the conical lower chamber 42, and the wall of the cylindrical upper chamber 41 continues to extend downward to construct the sedimentation tank 4 into a cylindrical outer wall 44. It can be seen that the cylindrical outer wall 44 avoids the lower conical lower chamber 42 from being exposed abruptly, making the overall structure neat. Furthermore, an annular cavity 43 is formed between the cylindrical outer wall 44 and the conical lower chamber 42, and the water pump 16 equipment is placed in the annular cavity 43, which can play the role of equipment placement and avoid the equipment being exposed. After the above structural optimization, the sedimentation tank 4 has a conical lower cavity 42, which has an inner conical surface, which is conducive to the realization of sedimentation. Although the conical lower cavity 42 is provided inside, the whole outside is a cylindrical outer wall 44, which can form a whole cylinder with the upper cylindrical aerobic tank 3. In terms of load-bearing, the double setting of the cylindrical outer wall 44 and the bracket 17 ensures the bearing strength of the whole equipment.

[0042] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
