[0041] 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.

[0042] Example 1: Please refer to Figures 1-3 Existing high-efficiency and energy-saving integrated MBR water treatment equipment filters impurities in wastewater through a filtration structure. However, these impurities remain on the filtration structure for a long time, making them inconvenient to clean. To solve this technical problem, this embodiment discloses the following technical content.

[0043] A high-efficiency and energy-saving integrated MBR water treatment equipment includes a filter box 1, an inlet pipe 2, a top cover 3, a waste collection rack 4, and a metal filter screen 5. The left end of the filter box 1 is connected to the inlet pipe 2, the top cover 3 is installed on the top of the filter box 1, the waste collection rack 4 is fixed at the bottom of the top cover 3, the metal filter screen 5 is set below the inlet pipe 2, the top cover 3 is connected to the filter box 1 by a slot connection, and the left and right sides of the metal filter screen 5 are fixedly connected to the left and right inner walls of the filter box 1, respectively. The longitudinal section of the metal filter screen 5 is a "V" shaped structure, and the front and rear sides of the metal filter screen 5 are attached to the waste collection rack 4. The bottom end of the waste collection rack 4 is a porous structure. The bottom of the inlet pipe 2 is set below the water inlet pipe 2. The upper and lower ends of the right side of the mounting plate 6 are fixed with a porous structure clamping plate 7, and the inner side of the clamping plate 7 is provided with an oil-absorbing felt 8.

[0044] During wastewater treatment, wastewater enters the interior of filter box 1 through inlet pipe 2 and falls onto metal filter screen 5. After being filtered by metal filter screen 5, the wastewater falls onto clamping plate 7 and oil-absorbing felt 8. Impurities remain on metal filter screen 5 and are absorbed by oil-absorbing felt 8. Since the longitudinal section of metal filter screen 5 is V-shaped, impurities flow along the inclined surface of metal filter screen 5 to waste collection rack 4. Water in the impurities flows down through the holes at the bottom of waste collection rack 4, and waste collection rack 4 is used to store impurities.

[0045] When it is necessary to remove impurities, lift the top cover 3 upwards and remove the top cover 3 and waste collection rack 4 from the inside of the filter box 1 to remove the impurities;

[0046] Example 2: Please refer to Figure 1 , Figure 3 and Figure 6 The existing high-efficiency and energy-saving integrated MBR water treatment equipment is inconvenient to disassemble the oil-absorbing felt 8. In order to solve this technical problem, this embodiment discloses the following technical content;

[0047] The mounting plate 6 and clamping plate 7 are connected to the filter box 1 by a slot connection. When it is necessary to remove the oil-absorbing felt 8 and replace it, pull the mounting plate 6 to the left to pull the mounting plate 6 and clamping plate 7 out of the filter box 1, and then remove the oil-absorbing felt 8 from the inside of the clamping plate 7 to replace it.

[0048] Example 3: Please refer to Figure 1 , Figure 3 and Figure 6 Existing high-efficiency and energy-saving integrated MBR water treatment equipment is inconvenient to stir the water, sludge and purification drugs in the activated sludge tank 10 and the disinfection tank 20 through the same mechanism. In order to solve this technical problem, the following technical contents are disclosed in this embodiment.

[0049] A disinfection tank 20 is provided below the activated sludge tank 10. A linkage mechanism is installed above the disinfection tank 20. The linkage mechanism includes a motor 16, a first gear 17, a second gear 18 and a stirring rod 19. The motor 16 is fixed on the upper surface of the disinfection tank 20. The first gear 17 is fixed at the output end of the motor 16. The second gear 18 is meshed with the left end of the first gear 17. The stirring rod 19 is fixed inside the second gear 18.

[0050] Start the motor 16. The motor 16 drives the first gear 17, the second gear 18 and the stirring rod 19 to rotate. The stirring rod 19 is rotatably installed inside the activated sludge tank 10 and the disinfection tank 20. The water, purification drugs and sludge inside the activated sludge tank 10 and the disinfection tank 20 are stirred by a set of stirring rods 19, reducing the use of power equipment.

[0051] Working principle: Wastewater enters the interior of filter box 1 through inlet pipe 2, and after being filtered by metal filter screen 5, it falls onto clamp plate 7 and oil-absorbing felt 8. Oil-absorbing felt 8 absorbs the oil in the wastewater, and impurities flow along the inclined surface of metal filter screen 5 to waste collection rack 4, where they are collected.

[0052] Open the control valve inside the first outlet pipe 9, and the sewage flows through the first outlet pipe 9 to the activated sludge tank 10. The activated sludge inside the activated sludge tank 10 comes into contact with the sewage. The aerator 11 continuously introduces oxygen into the activated sludge tank 10 through the distribution pipe 12. The motor 16 drives the stirring rod 19 to rotate and stir the activated sludge through the first gear 17 and the second gear 18, which accelerates the reaction between the microorganisms in the activated sludge and the sewage, and absorbs the organic matter in the sewage. The chemical pump 14 and the dosing pipe 15 transport the chemical solution inside the chemical tank 13 to the activated sludge tank 10 and the disinfection tank 20.

[0053] After a period of time, the control valve inside the second outlet pipe 21 is opened, and the sewage inside the activated sludge tank 10 flows to the MBR membrane treatment tank 22 through the second outlet pipe 21. After being treated by the MBR membrane module 23 inside the MBR membrane treatment tank 22, the large organic molecules of activated sludge are retained. Under the action of the first water pump 24, the water is transported to the disinfection tank 20 through the third outlet pipe 25. The water is mixed with the purification solution inside the disinfection tank 20 to disinfect the water. After a period of time, the valve at the bottom of the clean water delivery pipe 26 is opened, and the second water pump 27 is turned on. Under the action of the second water pump 27, the clean water is transported to the storage tank 28 through the clean water delivery pipe 26. The fourth outlet pipe 29 is connected to the external water-using equipment. When water is needed, the control valve inside the fourth outlet pipe 29 is opened, and then the water flows from the fourth outlet pipe 29 to the water-using equipment.

[0054] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
