Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an integrated wastewater purification device. Background Technology

[0002] With the acceleration of urbanization and the increase in industrial activities, wastewater discharge has risen sharply, and traditional wastewater treatment methods are no longer sufficient to meet the requirements of modern society for environmental quality and resource recovery. Therefore, the development of efficient, compact, easy-to-install and maintain wastewater treatment equipment has become a current research hotspot.

[0003] Traditional wastewater treatment plants typically consist of multiple independent treatment units, including primary treatment, secondary treatment, and advanced treatment. These units usually occupy a large area, have long construction periods, and high operating costs, and may generate secondary pollution during the treatment process. In addition, traditional wastewater treatment methods lack flexibility and responsiveness in dealing with water quality fluctuations and sudden pollution events. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated sewage purification equipment that can improve treatment efficiency, has a compact structure, is stable and reliable, and is easy to install and maintain.

[0005] An integrated wastewater treatment device includes a container body and a top cover covering the container body. The container body contains an equalization tank, an anoxic tank, and an aerobic tank. The aerobic tank contains an MBR membrane tank area, where an MBR membrane module is installed. A bar screen assembly is installed on the outer wall of the container body near the top cover. The bar screen assembly is connected to the equalization tank via a main inlet pipe. An equalization tank drain pipe is located at the bottom of the equalization tank. An anoxic tank drain pipe is located at the bottom of the anoxic tank and passes through the equalization tank. The MBR membrane tank area is equipped with a sludge return pipe and an effluent pipe. The outlet end of the sludge return pipe is located in the anoxic tank. The MBR membrane module is connected to a permeate hose assembly. One end of the effluent pipe is connected to the permeate hose assembly, and the other end passes through the container body. An overflow pipe is installed in the equalization tank, with one end passing through the container body.

[0006] In the above scheme, an MBR membrane tank area is set up in the aerobic tank and an MBR membrane module is installed, which realizes efficient solid-liquid separation and water purification. The MBR membrane module can significantly improve the wastewater treatment efficiency, reduce sludge production, and ensure that the effluent quality meets or even exceeds the discharge standards. The design of the equalization tank helps to homogenize and stabilize the flow rate, reduce the impact of water quality fluctuations on subsequent treatment units, and improve the stability of the system. The sewage pipes of the equalization tank and the anoxic tank can discharge excess sludge. Integrating multiple treatment units into a container significantly reduces the footprint, making it particularly suitable for use in cities and remote areas with limited land resources. Moreover, the equipment can be modularly expanded according to treatment needs, flexibly adapting to different treatment volumes and water quality requirements, improving the adaptability and application range of the equipment. At the same time, the container design facilitates transportation and installation, making it particularly suitable for temporary wastewater treatment needs and rapid deployment in emergency situations.

[0007] The containerized structural design means that the size of the equipment is strictly controlled, and every inch of space is fully utilized. Based on this, an overflow pipe is cleverly integrated into the system, effectively preventing overflows caused by abnormally high water levels, even in situations with limited internal space, ensuring the safety and stability of the overall equipment structure. In the face of rapidly changing working environments, the overflow pipe's rapid response capability is crucial. It can identify and alleviate situations of excessively high liquid levels in a very short time, especially valuable during peak processing periods, reducing the need for human intervention and making system operation more autonomous and controllable. Through pre-planned overflow channels, the impact of potential high water pressure on the equipment body can be effectively dispersed, thereby reducing the probability of long-term wear and damage, indirectly extending the equipment's service life, and reducing the cost of long-term maintenance and parts replacement. The containerized design advocates a closed treatment process, greatly reducing the impact of external environmental factors on the equipment. The overflow pipe further reinforces this isolation effect, ensuring that even in the event of an emergency, wastewater will not leak indiscriminately, minimizing the impact on the surrounding environment.

[0008] Furthermore, an aeration disc assembly is installed inside the aerobic tank. The aeration disc assembly includes an aeration pipe and an aeration disc. Multiple aeration discs are arranged on the aeration pipe and close to the bottom of the container body. One end of the aeration pipe passes through the upper cover.

[0009] In the above scheme, the aeration disc assembly fully dissolves oxygen from the air into the wastewater in the aerobic tank through aeration pipes and multiple aeration discs, providing the necessary conditions for the survival and reproduction of aerobic microorganisms. Sufficient oxygen supply can significantly improve the degradation efficiency of pollutants such as organic matter, nitrogen, and phosphorus. Multiple aeration discs are arranged on the aeration pipes, close to the bottom of the container, ensuring that the wastewater in each area of ​​the aerobic tank can obtain oxygen evenly, avoiding the problem of local hypoxia or insufficient oxygen, and improving the overall treatment efficiency.

[0010] Furthermore, the aerobic tank is equipped with a liquid level sensing component, which includes two supports, a high liquid level sensor, and a low liquid level sensor. The high liquid level sensor and the low liquid level sensor are vertically connected to the two supports respectively.

[0011] In the above scheme, the liquid level sensing component monitors changes in the liquid level in the aerobic tank in real time through high-level and low-level sensors. This real-time monitoring can promptly detect abnormal fluctuations in the liquid level, such as excessively high or low levels, thus preventing a decrease in treatment efficiency or system failure due to liquid level issues.

[0012] Furthermore, it also includes a dosing pipeline assembly, which is installed at the top of the aerobic tank.

[0013] In the above scheme, the dosing pipeline assembly can precisely control the amount of chemicals (such as nutrients, flocculants, etc.) added according to the real-time monitoring of wastewater quality and treatment needs. Precise dosing control can ensure that the chemicals play their role under optimal conditions, thereby improving the treatment effect and effluent quality.

[0014] Furthermore, a submersible mixer and a fixing assembly are installed at one corner of the anoxic pool. The fixing assembly includes a base plate and a first support column and a second support column vertically mounted on the base plate. The first support column is connected to a fixing ring, which is sleeved on the submersible mixer. The tail of the submersible mixer is connected to the second support column, which is a hollow structure that can be used for wiring.

[0015] In the above scheme, the submersible mixer can quickly agitate the sewage in the anoxic tank, achieving uniform mixing of the sewage. Uniform mixing ensures that the reagents, sludge, and organic matter in the sewage are in full contact, improving the efficiency of biological treatment. It can also prevent sludge from settling at the bottom of the anoxic tank, maintaining good suspension of the sludge, improving biological activity, and reducing sludge generation during the treatment process. The fixing assembly firmly fixes the submersible mixer to one corner of the anoxic tank through the base plate, the first support column, and the second support column, ensuring that the mixer will not shift or tilt during operation, improving the stability and safety of the equipment. The hollow structure of the second support column is used for cable routing, allowing the cables to be isolated from the sewage in the anoxic tank.

[0016] Furthermore, the grid assembly includes a trapezoidal basket grid and a rectangular grid water collection cover. The top periphery of the basket grid is provided with an overlapping strip, and the top periphery of the grid water collection cover is provided with a stepped portion, with the overlapping strip overlapping the stepped portion.

[0017] In the above solution, the bar screen collection hood is rectangular and used in conjunction with the basket bar screen to centrally collect debris and wastewater intercepted by the basket bar screen, facilitating subsequent treatment and discharge. The design of the bar screen collection hood makes debris collection and management easier. The top of the bar screen collection hood has a stepped section, and the overlapping strip of the top of the basket bar screen overlaps on the stepped section, ensuring the stability and sealing of the bar screen assembly. At the same time, this design facilitates regular cleaning and discharge of debris by operators, improving maintenance convenience.

[0018] Furthermore, the container body includes a frame, the four sides and the inner bottom of the frame are covered with steel plates, and the four sides and the outer bottom of the frame are covered with polyurethane insulation panels.

[0019] In the above scheme, the laying of steel plates on the inner four sides and bottom enhances the load-bearing capacity of the container, enabling it to withstand greater weight and pressure, ensuring the stability and safety of the equipment under full load operation. The polyurethane insulation board has a low thermal conductivity, which effectively reduces the conduction of temperature inside and outside the equipment, reduces energy consumption, and improves the system's energy efficiency ratio.

[0020] This integrated wastewater treatment equipment boasts advantages such as improved treatment efficiency, compact structure, stability, reliability, and convenient installation and maintenance. An MBR membrane tank zone is installed within the aerobic tank, enabling highly efficient solid-liquid separation and water purification. The MBR membrane module significantly improves wastewater treatment efficiency, reduces sludge production, and ensures that effluent quality meets or exceeds discharge standards. The equalization tank design facilitates homogenization and flow stabilization, reducing the impact of water quality fluctuations on subsequent treatment units and improving system stability. Excess sludge is discharged through the equalization tank and anoxic tank drain pipes. Integrating multiple treatment units into a single container significantly reduces floor space, making it particularly suitable for urban and remote areas with limited land resources. Furthermore, the equipment can be modularly expanded according to treatment needs, flexibly adapting to different treatment volumes and water quality requirements, thus improving its adaptability and application range. The container design also facilitates transportation and installation, making it particularly suitable for temporary wastewater treatment needs and rapid deployment in emergencies.

[0021] The containerized structural design means that the size of the equipment is strictly controlled, and every inch of space is fully utilized. Based on this, an overflow pipe is cleverly integrated into the system, effectively preventing overflows caused by abnormally high water levels, even in situations with limited internal space, ensuring the safety and stability of the overall equipment structure. In the face of rapidly changing working environments, the overflow pipe's rapid response capability is crucial. It can identify and alleviate situations of excessively high liquid levels in a very short time, especially valuable during peak processing periods, reducing the need for human intervention and making system operation more autonomous and controllable. Through pre-planned overflow channels, the impact of potential high water pressure on the equipment body can be effectively dispersed, thereby reducing the probability of long-term wear and damage, indirectly extending the equipment's service life, and reducing the cost of long-term maintenance and parts replacement. The containerized design advocates a closed treatment process, greatly reducing the impact of external environmental factors on the equipment. The overflow pipe further reinforces this isolation effect, ensuring that even in the event of an emergency, wastewater will not leak indiscriminately, minimizing the impact on the surrounding environment.

[0029] The integrated wastewater purification equipment of this utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0030] like Figure 1 and Figure 2 As shown, in a preferred embodiment, an integrated wastewater purification device includes a container body 1 and a top cover 3 covering the top of the container body 1. The container body 1 is provided with an equalization tank 4, an anoxic tank 5, and an aerobic tank 6. The aerobic tank 6 is provided with an MBR membrane tank area 7, and an MBR membrane module 8 is installed in the MBR membrane tank area 7. A bar screen assembly 2 is installed on the outer side wall of the container body 1 near the top cover 3. The bar screen assembly 2 is connected to the equalization tank 4 through a main inlet pipe 9. An equalization tank drain pipe 10 is provided at the bottom of the equalization tank 4. An anoxic tank drain pipe 11 is provided at the bottom of the anoxic tank 5 and passes through the equalization tank 4. A sludge return pipe 12 and an effluent pipe 20 are installed in the MBR membrane tank area 7. The outlet end of the sludge return pipe 12 is located in the anoxic tank 5. The MBR membrane module 8 is connected to a permeate hose assembly 13. One end of the effluent pipe 20 is connected to the permeate hose assembly 13, and the other end passes through the container body 1. An overflow pipe 19 is installed inside the regulating tank 4, with one end of the overflow pipe 19 passing through the container body 1.

[0031] An MBR membrane tank zone 7 is set up in the aerobic tank 6, and an MBR membrane module 8 is installed to achieve efficient solid-liquid separation and water purification. The MBR membrane module 8 can significantly improve the wastewater treatment efficiency, reduce sludge production, and ensure that the effluent quality meets or even exceeds the discharge standards. The design of the equalization tank 4 helps to homogenize and stabilize the flow rate, reduce the impact of water quality fluctuations on subsequent treatment units, and improve the stability of the system. The equalization tank drain pipe 10 and the anoxic tank drain pipe 11 can discharge excess sludge. Integrating multiple treatment units into a single container 1 significantly reduces the floor space required, making it particularly suitable for use in cities and remote areas with limited land resources. Moreover, the equipment can be modularly expanded according to treatment needs, flexibly adapting to different treatment volumes and water quality requirements, improving the adaptability and application range of the equipment. At the same time, the container 1 is designed for easy transportation and installation, making it particularly suitable for temporary wastewater treatment needs and rapid deployment in emergency situations.

[0032] The containerized structure design means that the size of the equipment is strictly controlled, and every inch of space is fully utilized. Based on this, the overflow pipe 19 is cleverly integrated into the system, effectively preventing overflows caused by abnormally high water levels, even in situations with limited internal space, ensuring the safety and stability of the overall equipment structure. In the face of rapidly changing working environments, the rapid response capability of the overflow pipe 19 is crucial. It can identify and alleviate situations of excessively high liquid levels in a very short time, especially valuable during peak processing periods, reducing the need for human intervention and making system operation more autonomous and controllable. Through pre-planned overflow channels, the impact of potential high water pressure on the equipment body can be effectively dispersed, thereby reducing the probability of long-term wear and damage, indirectly extending the service life of the equipment, and reducing the cost of long-term maintenance and replacement parts. The containerized design advocates a closed treatment process, greatly reducing the impact of external environmental factors on the equipment. The overflow pipe 19 further reinforces this isolation effect, ensuring that even in the event of an emergency, wastewater will not leak indiscriminately, minimizing the impact on the surrounding environment.

[0033] like Figure 2 and Figure 3As shown, in some embodiments, an aeration disc assembly 14 is installed inside the aerobic tank 6. The aeration disc assembly 14 includes an aeration pipe 141 and aeration discs 142. Multiple aeration discs 142 are arranged on the aeration pipe 141 and close to the bottom of the container body 1. One end of the aeration pipe 141 passes through the upper cover 3. The aeration disc assembly 14, through the aeration pipe 141 and multiple aeration discs 142, fully dissolves oxygen from the air into the wastewater in the aerobic tank 6, providing the necessary conditions for the survival and reproduction of aerobic microorganisms. Sufficient oxygen supply can significantly improve the degradation efficiency of pollutants such as organic matter, nitrogen, and phosphorus. The multiple aeration discs 142 arranged on the aeration pipe 141 and close to the bottom of the container body 1 ensure that the wastewater in each area of ​​the aerobic tank 6 can obtain oxygen evenly, avoiding the problem of local hypoxia or insufficient oxygen, and improving the overall treatment efficiency.

[0034] like Figure 2 and Figure 3 As shown, in some embodiments, the aerobic tank 6 is equipped with a liquid level sensing component 15. The liquid level sensing component 15 includes two supports 151, a high liquid level sensor 153, and a low liquid level sensor 152. The high liquid level sensor 153 and the low liquid level sensor 152 are vertically connected to the two supports 151 respectively. The liquid level sensing component 15 monitors the changes in the liquid level in the aerobic tank 6 in real time through the high liquid level sensor 153 and the low liquid level sensor 152. This real-time monitoring can promptly detect abnormal fluctuations in the liquid level, such as being too high or too low, avoiding a decrease in treatment efficiency or system failure due to liquid level issues.

[0035] like Figure 2 and Figure 3 As shown, in some embodiments, a dosing pipeline assembly 16 is also included, which is installed on the upper part of the aerobic tank 6. The dosing pipeline assembly 16 can precisely control the amount of chemicals (such as nutrients, flocculants, etc.) added according to the real-time monitoring of wastewater quality and treatment requirements. Precise dosing control can ensure that the chemicals work under optimal conditions, thereby improving the treatment effect and effluent quality.

[0036] like Figure 2 and Figure 4As shown, in some embodiments, a submersible mixer 17 and a fixing assembly are installed at one corner of the anoxic pool 5. The fixing assembly includes a base plate 181 and a first support column 182 and a second support column 184 vertically mounted on the base plate 181. The first support column 182 is connected to a fixing ring 183, which is sleeved on the submersible mixer 17. The tail of the submersible mixer 17 is connected to the second support column 184. The second support column 184 is a hollow structure that can be used for wiring. The submersible mixer 17 can quickly agitate the sewage in the anoxic tank 5, achieving uniform mixing of the sewage. Uniform mixing ensures that the reagents, sludge, and organic matter in the sewage are in full contact, improving the efficiency of biological treatment. It can also prevent sludge from settling at the bottom of the anoxic tank 5, maintaining good suspension of the sludge, improving biological activity, and reducing sludge generation during the treatment process. The fixing assembly securely fixes the submersible mixer 17 to one corner of the anoxic tank 5 through the base plate 181, the first support column 182, and the second support column 184, ensuring that the mixer will not shift or tilt during operation, improving the stability and safety of the equipment. The hollow structure of the second support column 184 is used for cable routing, allowing the cable to be isolated from the sewage in the anoxic tank 5.

[0037] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, the grille assembly 2 includes a trapezoidal basket grille 21 and a rectangular grille collection hood 22. The basket grille 21 has an overlapping strip 211 on its top periphery, and the grille collection hood 22 has a stepped portion 221 on its top periphery, with the overlapping strip 211 overlapping the stepped portion 221. The rectangular grille collection hood 22, used in conjunction with the basket grille 21, can centrally collect debris and wastewater intercepted by the basket grille 21, facilitating subsequent treatment and discharge. The design of the grille collection hood 22 makes debris easier to collect and manage. The stepped portion 221 on the top of the grille collection hood 22, with the overlapping strip 211 on the top of the basket grille 21 overlapping the stepped portion 221, ensures the stability and sealing of the grille assembly 2. Simultaneously, this design facilitates regular cleaning and discharge of debris by operators, improving maintenance convenience.

[0038] like Figure 2 and Figure 3 As shown, in some embodiments, the container body 1 includes a frame 101, with steel plates 102 laid on the four sides and the inner bottom surface of the frame 101, and polyurethane insulation panels 103 installed on the four sides and the outer bottom surface of the frame 101. The laying of steel plates 102 on the inner four sides and bottom surface enhances the load-bearing capacity of the container body 1, enabling it to withstand greater weight and pressure, ensuring the stability and safety of the equipment under full-load operation. The polyurethane insulation panels 103 have a low thermal conductivity, effectively reducing the conduction of temperature between the inside and outside of the equipment, reducing energy consumption, and improving the system's energy efficiency ratio.

[0039] The working principle and process of this integrated sewage purification equipment are as follows: Sewage enters the bar screen assembly 2 through the main inlet pipe 9. The bar screen assembly 2 is installed on the outer wall of the container body 1 near the upper cover 3. The sewage treated by the bar screen assembly 2 enters the equalization tank 4. Through the overflow function of the overflow pipe 19, the liquid level in the equalization tank 4 is kept stable, reducing fluctuations in water volume and quality, and ensuring the stable operation of subsequent treatment units. The equalization tank 4 is equipped with an equalization tank drain pipe 10 at the bottom for periodically discharging settled sludge. The effluent from the equalization tank 4 enters the anoxic tank 5, where anoxic microorganisms continue to degrade organic matter and carry out nitrification under low-oxygen or anaerobic conditions. The anaerobic tank 5 undergoes nitrification and denitrification reactions to remove nutrients such as nitrogen and phosphorus. An anoxic tank 5 has an anoxic tank drain pipe 11 at its bottom for periodically discharging settled sludge. A submersible mixer 17 and a fixing assembly are installed at one corner of the anoxic tank 5 to ensure uniform mixing. The effluent from the anoxic tank 5 enters the aerobic tank 6, where aerobic microorganisms (such as bacteria in activated sludge) decompose organic matter under aeration conditions, producing water and carbon dioxide. An aeration disc assembly 14, including aeration pipes 141 and aeration discs 142, is installed inside the aerobic tank 6. Multiple aeration discs 142 are arranged on the aeration pipes 141 and near the bottom of the container body 1 to provide sufficient oxygen. One end of the aeration pipe 141 passes through the upper cover 3 and connects to the external air supply system. Some activated sludge and treated water enter the MBR membrane tank area 7. Through the microporous filtration of the MBR membrane module 8, suspended solids and organic matter are effectively removed, improving the quality of the effluent. The MBR membrane tank area 7 is equipped with a sludge return pipe 12 and an effluent pipe 20. The outlet end of the sludge return pipe 12 is located in the anoxic tank 5 to realize the recycling of sludge. The MBR membrane module 8 is connected to a permeate hose assembly 13. The other end of the permeate hose assembly 13 is connected to the effluent pipe 20. The effluent pipe 20 passes through the container body 1 and discharges the treated water.
