Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an emergency pool structure for a wastewater treatment plant. Background Technology

[0002] Wastewater treatment refers to the process of using physical, chemical, or biological technologies to separate, remove, recycle, or convert pollutants in wastewater into harmless substances, so that the water quality meets the standards for discharge or reuse.

[0003] Emergency pools in wastewater treatment plants are facilities used to collect and treat wastewater in the event of an accident, preventing contaminated water from entering the external environment and causing pollution. The primary purpose of an emergency pool is to quickly collect wastewater with high concentrations and abnormal pH levels when a wastewater treatment system malfunctions or experiences an accident, preventing untreated wastewater from being directly discharged into natural water bodies or the wastewater treatment system and causing a shock. For example, a chemical plant accident may result in the discharge of pollutants such as leaked substances and fire-fighting wastewater; the emergency pool temporarily stores this wastewater, buying time for subsequent treatment.

[0004] Conventional emergency pool structures, due to their structural design, make the components used for water filtration relatively complex to maintain and have high maintenance and usage costs, thus hindering the widespread use of these components. Utility Model Content

[0005] The purpose of this invention is to provide an emergency pool structure for a wastewater treatment plant to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an emergency pool structure for a sewage treatment plant, comprising a base and filter components. A pool body is provided on the top of the base, and a first partition wall is vertically provided at the front end of the pool body. A second partition wall is vertically provided at the end of the pool body away from the first partition wall. The filter components are equidistantly arranged between the first and second partition walls. An auger component is horizontally mounted on the side of the second partition wall away from the filter components. A servo motor is connected to one end of the auger component. A limiting groove is provided at the junction of the inner wall surface of the pool body and the filter components. The filter components include a support frame, filter screens, and filter aggregate. Filter screens are symmetrically arranged in the middle of the support frame, and filter aggregate is filled between the two sets of filter screens.

[0007] Preferably, the lower end of the front facade of the pool is symmetrically and horizontally provided with feed valve pipes, and two sets of drain valve pipes are symmetrically and horizontally installed on the left and right sides of the front end of the pool.

[0008] Preferably, a conveying valve pipe is symmetrically and horizontally installed on the upper end of the second partition wall, and a drain valve pipe is symmetrically installed on the upper end of the rear facade of the pool body, with one end of the drain valve pipe extending vertically to the lower end of the interior of the pool body.

[0009] Preferably, the four side facades of the pool body are equidistantly arranged with buttresses at the junctions with the base, and the buttresses, the pool body, and the base are all integrally cast with concrete.

[0010] Preferably, the filter element and the first partition wall and the second partition wall are parallel to each other, and the first partition wall is lower than the height of the inner wall of the pool.

[0011] Preferably, the internal surface structure of the limiting groove matches the external surface structure of the left and right sides and the bottom of the support frame, and the filter aggregate is made of quartz sand filter material.

[0012] Preferably, the auger component and the servo motor are both horizontally mounted on two sets on the side of the second partition wall away from the filter component, and one end of the auger component is connected to the power output end of the servo motor through a coupling.

[0013] Preferably, the feed valve pipe, drain valve pipe, conveying valve pipe, and liquid discharge valve pipe are all configured with a one-way valve structure. The servo motor is horizontally installed on the outside of the tank body. The side of the first partition wall away from the filter component is separated from the tank body to form a space structure for sewage sedimentation. The second partition wall and the first partition wall are separated to form a space structure for sewage filtration. The side of the second partition wall away from the filter component is separated from the tank body to form a space structure for sewage disinfection.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The emergency pool structure of the sewage treatment plant is equipped with multiple sets of filter components arranged in a manner that utilizes quartz sand filter media. The material properties of the quartz sand filter media ensure sufficient filtration performance while also providing good durability and applicability, thereby effectively reducing the cost of using the filter components. The structure of the limiting groove facilitates the maintenance and treatment of the filter components and ensures the structural stability of the structure. In addition, the structure of the buttress body ensures the structural strength of the pool itself, thereby preventing the structure from being damaged due to water pressure. The emergency pool structure of this wastewater treatment plant is equipped with filter components. Through a sliding insertion structure between the limiting groove and the support frame, the filter components are stably installed in the space between the first and second partition walls. This allows for rapid installation of the filter components and ensures convenient and simple operation. The filter aggregate is made of quartz sand, which possesses excellent filtration performance. Through crushing, washing, and screening, the quartz sand has a multi-faceted structure, resulting in strong interception capacity and high chemical stability, making it suitable for treating common pollutants such as oily wastewater and suspended solids. It also exhibits good durability: its material characteristics include a long service life, low maintenance costs, and rapid recovery of filtration performance after backwashing. Furthermore, it has good applicability: its material is suitable for extreme water quality environments with pH values ​​of 2-13, is acid and alkali resistant, and anti-aging. Therefore, the entire filter component has both good structural practicality and is easy to maintain, while minimizing maintenance costs. The emergency tank structure of this wastewater treatment plant features a first partition wall slightly lower than the inner wall of the tank. The space created between the tank and the first partition wall facilitates wastewater sedimentation. The relatively clean water that settles at the top of this space flows through the first partition wall into the space between the first and second partition walls, allowing for effective filtration by the filter components. The auger structure allows for the disinfection of the filtered water within the space enclosed by the second partition wall and the tank. A servo motor drives the directly connected auger component to rotate horizontally. This design allows for rapid mixing of the agitated water and disinfectant, ensuring effective disinfection. Furthermore, the structure of the buttresses is designed to resist the thrust of arches or vaults, enhancing the stability of the pool's side structure. This balances the structural thrust exerted by the water on the pool's sides, maximizing the pool's structural strength and ensuring its safety and stability. It also prevents unnecessary structural damage leading to wastewater leakage. Additionally, the inlet valve, drain valve, conveying valve, and liquid discharge valve all employ one-way valve designs to prevent cross-contamination of wastewater from different areas, thus avoiding any impact on wastewater treatment.

[0018] Please see Figure 1-3 This utility model provides a technical solution: an emergency pool structure for a sewage treatment plant, including a base 1 and filter components 5. A pool body 2 is provided on the top of the base 1, and a first partition wall 3 is vertically arranged at the front end of the pool body 2. A second partition wall 4 is vertically arranged at the end of the pool body 2 away from the first partition wall 3. Filter components 5 are arranged equidistantly between the first partition wall 3 and the second partition wall 4. An auger component 6 is horizontally mounted on the side of the second partition wall 4 away from the filter components 5, and a servo motor 7 is connected to one end of the auger component 6. A limiting groove 8 is provided at the junction of the inner wall surface of the pool body 2 and the filter components 5. The filter components 5 include a support frame 501, a filter screen 502, and filter aggregate 503. The support frame 501 is symmetrically equipped with filter screens 502 in the middle front and back, and filter aggregate 503 is filled between the two sets of filter screens 502. The internal surface structure of the limiting groove 8 matches the external surface structure of the left and right sides and bottom of the support frame 501. The filter aggregate 503 is made of quartz sand filter material. The lower end of the front facade of the pool body 2 is symmetrically equipped with feed valve pipes 9, and the front left and right sides of the pool body 2 are symmetrically equipped with two sets of sewage discharge valve pipes 10. The upper end of the second partition wall 4 is symmetrically equipped with conveying valve pipes 11. The upper end of the rear facade of the pool body 2 is symmetrically equipped with drain valve pipes 12, and one end of the drain valve pipe 12 extends vertically to the lower end of the interior of the pool body 2.

[0019] When using the emergency pool structure of this wastewater treatment plant, such as Figure 1 and Figure 3As shown, firstly, filter screens 502 filled with filter aggregate 503 are placed in the middle of the two sets of filter screens 502. Using the structure of the support frame 501, multiple sets of filter components 5 are inserted one by one into the limiting groove 8 opened on the middle section surface of the tank body 2 through the vertical sliding insertion structure. Then, the tank body 2 is connected to the upstream sewage supply equipment through the feed valve pipe 9, so that the sewage will flow directly into the space separated from the front end of the tank body 2 and the first partition wall 3. With the help of the agent used for sewage sedimentation treatment, the sewage will begin to be initially treated. Meanwhile, the four side facades of the pool body 2 are equidistantly arranged with buttresses 13 at the junction with the base 1. The buttresses 13, the pool body 2, and the base 1 are all integrally cast with concrete. The filter components 5 and the first partition wall 3 and the second partition wall 4 are parallel to each other. The first partition wall 3 is lower than the inner wall height of the pool body 2. The auger components 6 and the servo motor 7 are horizontally mounted in two sets on the side of the second partition wall 4 away from the filter components 5. One end of the auger components 6 is connected to the power output end of the servo motor 7 through a coupling. The feed valve pipe 9, the drain valve pipe 10, the conveying valve pipe 11, and the drain valve pipe 12 are all set with a one-way valve structure. The servo motor 7 is horizontally installed on the outside of the pool body 2. The side of the first partition wall 3 away from the filter components 5 is separated from the pool body 2 to form a space structure for sewage sedimentation. The second partition wall 4 and the first partition wall 3 are separated to form a space structure for sewage filtration. The side of the second partition wall 4 away from the filter components 5 is separated from the pool body 2 to form a space structure for sewage disinfection.

[0020] After sedimentation, the wastewater overflows through the first partition wall 3 and enters the space between the first partition wall 3 and the second partition wall 4, which are equipped with filter components 5. Under the action of multiple filter components 5, the wastewater is effectively filtered. Then, with the cooperation of the conveying valve pipe 11, the filtered water enters the space enclosed by the second partition wall 4 and the pool body 2. The disinfectant is added inside, and under the operation of the servo motor 7, the auger component 6 connected to its power output end rotates horizontally, thereby quickly mixing the water and the disinfectant to ensure the efficiency of disinfection. Afterwards, with the assistance of the drain valve pipe 12, the treated water is discharged or transported to downstream treatment equipment. This is the working principle of the emergency pool structure of the wastewater treatment plant.
