Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an impurity adsorption device for wastewater treatment based on MABR. Background Technology

[0002] In today's society, with the rapid development of industry and the continuous acceleration of urbanization, the amount of sewage discharge is increasing day by day, and the composition of sewage is becoming more and more complex. Sewage contains a large amount of suspended solids, organic matter, nutrients such as nitrogen and phosphorus, as well as various harmful substances. If it is discharged directly without effective treatment, it will cause serious damage to natural water bodies, soil and ecological environment, thereby threatening human health and quality of life. Among the traditional sewage treatment methods, physical treatment methods include sedimentation and centrifugation, but these methods have their own shortcomings. For example, sedimentation is not effective in removing fine particles and dissolved pollutants, while chemical treatment removes pollutants by adding agents, but the agents are expensive, may cause secondary pollution, and have limited effectiveness in treating complex organic matter. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: an impurity adsorption device for wastewater treatment based on MABR, comprising: a bottom fixed support plate 1; a water sedimentation tank 2 disposed on the top of the bottom fixed support plate 1; a filter box 4 installed on the top of the bottom fixed support plate 1 by bolts, with an outlet pipe 3 on one side of the water sedimentation tank 2, the outlet pipe 3 being connected to the filter box 4; a filter screen 6 installed inside the filter box 4, with a connecting pipe 8 fixedly connected to one side of the filter box 4; a treatment box 10 disposed on the top of the bottom fixed support plate 1, with multiple aeration pipes 11 disposed inside the treatment box 10, the connecting pipe 8 being connected to the treatment box 10; a support frame 12 symmetrically fixed inside the treatment box 10, with a biofilm assembly 13 disposed inside the support frame 12; a pumping tank 14 disposed on the top of the support frame 12, with a collecting water pipe 15 connected above the pumping tank 14 via a pump body; and a three-way control valve 16 installed at one end of the collecting water pipe 15, with a filter assembly disposed on one side of the three-way control valve 16.

[0027] It should be noted that in this embodiment, the wastewater first enters the sedimentation tank 2 located on top of the bottom fixed support plate 1. Inside the sedimentation tank 2, larger particles of impurities in the wastewater gradually settle to the bottom of the tank due to gravity, achieving preliminary sedimentation and separation. After preliminary sedimentation, the wastewater flows through the outlet pipe 3 located on one side of the sedimentation tank 2 into the connected filter tank 4. A filter screen 6 is installed inside the filter tank 4. When the wastewater enters the filter tank 4, the filter screen 6 further intercepts suspended solids in the wastewater, thus achieving preliminary purification. Two overflow pipes 7 located on one side of the filter tank 4 serve a safety protection function. When the inflow rate exceeds the processing capacity of the filter tank 4, the overflow pipes 7 automatically discharge excess wastewater, preventing backflow or equipment damage due to excessively high water levels. The discharge pipe 9 and the control valve installed at the bottom of the filter box 4 facilitate the periodic discharge of impurities deposited at the bottom of the filter box 4, reducing the risk of clogging. The top maintenance plate 5 of the filter box 4 is bolted to the top, and its bottom is also bolted to the filter screen 6. Operators can quickly remove the top maintenance plate 5 to expose the filter screen 6 for direct cleaning or replacement, reducing equipment downtime. It also allows for periodic inspection of the condition of the filter screen 6, timely detection and repair of damage, and prevention of impurities from entering subsequent treatment stages, protecting core components. The wastewater initially purified by the filter box 4 flows into the treatment box 10, which is located on the top of the bottom fixed support plate 1, through the connecting pipe 8 on one side of the filter box 4. The treatment box 10 contains multiple aeration pipes 11, which serve as the aeration pipes for the treatment box 10. The biofilm component 13 provides ample oxygen, and the support frame 12 is symmetrically fixed inside the treatment tank 10, stably supporting the biofilm component 13 and ensuring full contact between the biofilm and the wastewater. In an environment with sufficient oxygen, the aerobic microorganisms on the biofilm component 13 carry out active metabolic activities, accelerating the decomposition of organic matter in the wastewater and effectively removing nutrients such as nitrogen and phosphorus, achieving highly efficient wastewater purification. This synergistic effect of biofilm and aeration greatly enhances the purification efficiency. The biofilm component 13 degrades pollutants through the metabolic degradation of pollutants by the microbial film attached to the carrier surface. Its carrier structure facilitates solid-liquid separation. Its core components include a microbial attachment carrier and a matching fluid distribution and maintenance system. The treated wastewater is pumped out through a pump located at the top of the support frame 12. Water from tank 14 is drawn into collecting pipe 15 by pump. A three-way control valve 16 is installed at one end of collecting pipe 15 to control the water flow. Connecting pipes 17 are installed at both ends of the three-way control valve 16. Connecting pipes 17 are connected to a fixed cover 19 at the bottom of a fixed bracket 18 located on one side of the bottom fixed support plate 1. The filter assembly consists of fixed bracket 18, fixed cover 19, connecting housing 21, and filter element 20. The connecting housing 21 is threaded onto the bottom of fixed cover 19. Filter element 20 is installed inside connecting housing 21 and fixed cover 19. This threaded installation design allows for the removal and replacement of filter element 20 without complicated tools, enabling operators to quickly complete the replacement, reducing downtime. The modular structure facilitates the replacement of filter element 20 individually, eliminating the need to replace the entire filter assembly.To reduce spare parts costs, filter elements 20 of different materials or precision can be flexibly selected according to the characteristics of wastewater impurities, improving the equipment's adaptability to different water quality conditions. The guide water tank 23, fixed inside the fixed cover 19, works in conjunction with the filter element 20. Water filtered by the filter element 20 flows into the guide water tank 23 and is then discharged through the drain pipe 22 on one side of the guide water tank 23, reducing impurity residue at the drain outlet, lowering the risk of secondary pollution, and enabling the filter element 20 to intercept impurities more efficiently.

[0028] In one embodiment, such as Figures 1 to 5 As shown, the filter assembly includes a fixed bracket 18, a fixed cover 19, a connecting housing 21, and a filter element 20. Both ends of the three-way control valve 16 are equipped with connecting water pipes 17. A fixed bracket 18 is provided on one side of the bottom fixed support plate 1. Fixed covers 19 are symmetrically installed on the bottom of the fixed bracket 18. The fixed covers 19 are connected to the connecting water pipes 17. The connecting housing 21 is threaded onto the bottom of the fixed cover 19. The filter element 20 is installed inside the connecting housing 21 and the fixed cover 19.

[0029] It should be noted that, in this embodiment, the filter assembly includes a fixed bracket 18, a fixed cover 19, a connecting housing 21, and a filter element 20. The threaded design of the connecting housing 21 and the fixed cover 19 allows the filter element 20 to be disassembled and replaced without complicated tools, enabling operators to quickly complete the replacement and shortening downtime. The modular structure facilitates the replacement of the filter element 20 individually, eliminating the need to replace the entire filter assembly and reducing spare parts costs. Filter elements 20 of different materials or precision can be flexibly selected according to the characteristics of wastewater impurities, improving the equipment's adaptability to different water quality conditions.

[0030] In one embodiment, such as Figure 4 and Figure 5 As shown, a water outlet tank 23 is fixedly connected inside the fixed cover 19. The water outlet tank 23 cooperates with the filter element 20, and a drain pipe 22 is provided on one side of the water outlet tank 23.

[0031] It should be noted that, in this embodiment, the cooperative structure of the water tank 23 and the filter element 20 allows the filtered water to flow into the drain pipe 22, reducing the residue of impurities at the drain outlet, reducing the risk of secondary pollution, and enabling the filter element 20 to intercept impurities more efficiently.

[0032] In one embodiment, such as Figures 1 to 3 As shown, a top maintenance plate 5 is bolted to the top of the filter box 4, and the bottom of the top maintenance plate 5 is bolted to the filter screen 6.

[0033] It should be noted that in this embodiment, the bolt-fixed top maintenance plate 5 can be quickly disassembled to expose the filter screen 6, which is convenient for operators to directly clean or replace the filter screen 6, reducing equipment downtime. Regularly checking the condition of the filter screen 6 through the top maintenance plate 5 can promptly detect and repair damage, prevent impurities from entering subsequent processing stages, and protect core components such as the biofilm assembly 13.

[0034] In one embodiment, such as Figure 2 As shown, two overflow pipes 7 are provided on one side of the filter box 4.

[0035] It should be noted that in this embodiment, when the influent flow rate exceeds the processing capacity of the filter box 4, the overflow pipe 7 automatically discharges the excess sewage to prevent sewage backflow or equipment damage due to excessively high water levels.

[0036] In one embodiment, such as Figure 3 As shown, a waste discharge pipe 9 is provided at the bottom of the filter box 4, and a material control valve is installed on the waste discharge pipe 9.

[0037] It should be noted that in this embodiment, the material control valve can adjust the opening of the discharge pipe 9 to discharge impurities in the filter box 4.
