Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a diversion and regulation device for a membrane integrated system for recycled water. Background Technology

[0002] Membrane modules are the core unit of wastewater treatment, determining treatment efficiency and effluent quality. They can retain different pollutants through precise pore size, such as ultrafiltration to retain bacterial colloids and reverse osmosis for deep desalination, solving the problem of small molecule impurities that are difficult to remove by traditional processes. At the same time, membrane modules ensure stable effluent quality, unaffected by fluctuations in influent, and can also reduce sludge volume and land occupation. In greywater reuse, they are key to achieving wastewater reuse that meets standards, directly affecting whether the system can meet the water quality requirements of different scenarios such as greening and industrial cooling.

[0003] In the current field of wastewater treatment and reclaimed water reuse, membrane modules are mostly operated in a single fixed configuration. When faced with fluctuations in influent water quality, this type of design cannot flexibly adjust the treatment unit according to the degree of wastewater pollution. If low-pollution wastewater flows through high-specification membrane modules, it is easy to cause over-treatment and energy waste. If high-pollution wastewater directly enters low-tolerance membrane modules, it will accelerate membrane pore blockage and scaling, shorten the service life of membrane modules, and increase replacement and maintenance costs. It is difficult to adapt to the complex and ever-changing actual wastewater treatment needs. Therefore, we propose a diversion and regulation device for a reclaimed water reuse membrane integrated system. Utility Model Content

The second water pump then draws the water from the first collection tank to the second delivery pipe, where it is purified again by the membrane module below the second delivery pipe before entering the second collection tank. Similarly, the third water pump draws the water from the second collection tank to the third delivery pipe, where it is purified again by the membrane module below the third delivery pipe. This further enhances the wastewater purification effect and meets usage requirements. Attached Figure Description

Detailed Implementation

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-4 As shown, a diversion and adjustment device for a membrane integrated system for greywater reuse includes a detection tank 1, a main filter plate 3, and three purification chambers 14 located below the detection tank 1. An installation frame 2 is fixedly connected to the inner wall of the detection tank 1, and the main filter plate 3 is movably engaged with the installation frame 2. A detection mechanism 4 is provided inside the cavity of the detection tank 1. Membrane modules are detachably installed in the cavities of the three purification chambers 14, and the three membrane modules have different filtration effects. The detection mechanism 4 includes a fixed plate 41 fixedly connected to the inner wall of the detection tank 1. Below the fixed plate 41, a sliding lifting plate 45 and a rotatable agitator 47 are provided. A sensor 46 is fixedly installed on the bottom surface of the lifting plate 45. The position of the lifting plate 45 can be adjusted. The stirring component 47 is driven to rotate. Three drain pipes are fixedly inserted into the bottom of the detection tank 1, and each of the three drain pipes is fitted with a first valve. The bottom ends of the three drain pipes flow to the three purification chambers 14 respectively. The detection mechanism 4 also includes a rotating motor 42 fixedly installed on the top surface of the fixed plate 41. The output end of the rotating motor 42 passes through the wall of the fixed plate 41 and is fixedly connected to a threaded rod 43. The bottom surface of the fixed plate 41 is also fixedly connected to a limit rod 44. The lifting plate 45 is threadedly sleeved on the threaded rod 43 and slidably connected to the limit rod 44. The stirring component 47 is fixedly sleeved on the circumferential surface of the threaded rod 43, and the bottom end of the threaded rod 43 is rotatably connected to the bottom surface of the inner cavity of the detection tank 1.

[0020] It should be noted that the first filter plate 8 has the worst filtration effect, the third filter plate 10 has the best filtration effect, and the filtration effect of the second filter plate 9 is between that of the first filter plate 8 and the third filter plate 10. The membrane module in the purification chamber 14 below the first filter plate 8 has the worst purification effect, the membrane module in the purification chamber 14 below the third filter plate 10 has the best purification effect, and the membrane module in the purification chamber 14 below the drain pipe 19 has a purification effect between the other two purification chambers 14.

[0021] In specific implementation, wastewater is added into the detection tank 1 from the main filter plate 3. The main filter plate 3 performs preliminary filtration of the wastewater. The output end of the rotating motor 42 drives the threaded rod 43 to rotate. The rotation of the threaded rod 43 causes the lifting plate 45 to slide downwards. While the lifting plate 45 moves, the agitator 47 rotates. The detection head of the sensor 46 comes into contact with the wastewater to detect the wastewater and determine the pollution level of the wastewater. The agitation of the agitator 47 can prevent the sedimentation of impurities in the wastewater in the detection tank 1, which is convenient for the sensor 46 to detect. According to the wastewater level in the detection tank 1, one of the first valves is opened, and the wastewater is extracted by the corresponding first water pump 5. The wastewater is then treated using the designated filter box 7 and purification chamber 14, which can save energy and prevent impurities in the wastewater from damaging the membrane module, thus extending the service life of the membrane module.

[0022] As a technical optimization of this utility model, three first water pumps 5 are fixedly connected to the bottom surface of the detection tank 1. The bottom ends of three drain pipes are respectively fixedly connected to the inlet ends of the three first water pumps 5. The drain ends of the three first water pumps 5 are all fixedly connected to first connecting pipes 6. The bottom ends of the three first connecting pipes 6 are all fixedly connected to filter boxes 7. The inner cavities of the three filter boxes 7 are respectively movably inserted with first filter plates 8, second filter plates 9, and third filter plates 10. The bottom ends of the three filter boxes 7 are respectively fixedly connected to first conveying pipes 11, second conveying pipes 12, and third conveying pipes 13. The bottom ends of the first conveying pipes 11, second conveying pipes 12, and third conveying pipes 13 are respectively fixedly connected to the top ends of three purification chambers 14. The bottom ends of the three purification chambers 14 are all fixedly connected to second connecting pipes 15. The bottom ends of the three second connecting pipes 15 are respectively fixedly connected to first collection boxes 16, second collection boxes 17, and third collection boxes 18. The bottoms of the first collection boxes 16, second collection boxes 17, and third collection boxes 18 are all fixedly connected to... A drain pipe 19 is provided, and a second valve 20 is fitted onto the surface of the drain pipe 19. A second water pump 21 is fixedly installed on the top surface of the first collection tank 16. The inlet end of the second water pump 21 is fixedly connected to a first vertical pipe, and the bottom end of the first vertical pipe passes through the wall of the first collection tank 16 and is located at the bottom surface of the inner cavity of the first collection tank 16. The drain end of the second water pump 21 is fixedly connected to a first L-shaped pipe 22. The end of the first L-shaped pipe 22 away from the second water pump 21 is fixedly connected to the wall of the second delivery pipe 12. 22 is connected to the second conveying pipe 12. The top surface of the second collection box 17 is fixedly installed with a third water pump 23. The inlet end of the third water pump 23 is fixedly connected to a second vertical pipe. The bottom end of the second vertical pipe passes through the box wall of the second collection box 17 and is located at the bottom surface of the inner cavity of the second collection box 17. The outlet end of the third water pump 23 is fixedly connected to a second L-shaped pipe 24. The end of the second L-shaped pipe 24 away from the third water pump 23 is fixedly connected to the pipe wall of the third conveying pipe 13, and the second L-shaped pipe 24 is connected to the third conveying pipe 13.

[0023] In practice, when the purified water in the first collection tank 16 and the second collection tank 17 cannot meet the usage requirements, the second water pump 21 is started to draw the water in the first collection tank 16 to the second delivery pipe 12, where it is purified again by the membrane module below the second delivery pipe 12, and then enters the second collection tank 17. Similarly, the third water pump 23 is used to draw the water in the second collection tank 17 to the third delivery pipe 13, where it is purified again by the membrane module below the third delivery pipe 13. This can further improve the wastewater purification effect and meet the usage requirements. The purified water inside the first collection tank 16, the second collection tank 17, and the third collection tank 18 can be discharged by opening the second valve 20 at the corresponding locations.

[0024] In use, wastewater is added to the detection tank 1 from the main filter plate 3. The main filter plate 3 performs preliminary filtration of the wastewater. The output end of the rotating motor 42 drives the threaded rod 43 to rotate, which in turn causes the lifting plate 45 to slide downwards. While the lifting plate 45 moves, the stirring component 47 rotates. The detection head of the sensor 46 contacts the wastewater to detect it and determine the pollution level. Based on the pollution level, one of the first valves is opened, and the corresponding first water pump 5 draws out the wastewater. The wastewater is then treated using the designated filter box 7 and purification chamber 14, and finally enters the first collection box 16, the second collection box 17, and the third collection box. Within one of the three collection tanks 16, 17, and 18, the purified water can be discharged by opening the corresponding second valves 20. When the purified water in the first and second collection tanks 16 and 17 is insufficient to meet the usage requirements, the second water pump 21 is activated to draw the water from the first collection tank 16 to the second delivery pipe 12, where it is purified again by the membrane module below the second delivery pipe 12, and then enters the second collection tank 17. Similarly, the third water pump 23 draws the water from the second collection tank 17 to the third delivery pipe 13, where it is purified again by the membrane module below the third delivery pipe 13, thereby further improving the wastewater purification effect to meet the usage requirements.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
