[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a modular wastewater treatment device. Background Technology

[0002] With the acceleration of urbanization and the continuous development of industrial production, wastewater treatment has become a crucial aspect of environmental protection. The rapid growth of the urban population and the increasing frequency of industrial activities have led to the discharge of large amounts of wastewater. If this wastewater is not effectively treated, it will cause serious pollution to water bodies, soil, and air, threatening human health and the balance of the ecological environment. Therefore, wastewater treatment is not only a necessary measure for environmental protection but also a key link in achieving sustainable development.

[0003] Most current wastewater treatment equipment is of an integrated structure, making it bulky and difficult to move. Furthermore, if the equipment cannot be freely assembled, changes in wastewater treatment needs require workers to replace the entire system, rather than adjusting the treatment capacity by replacing or adding specific components. This not only increases replacement costs but also reduces installation efficiency. Utility Model Content

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.

[0028] According to an embodiment of the present invention, a modular sewage treatment device is provided.

[0029] like Figures 1-4As shown, the assembled sewage treatment equipment according to an embodiment of this utility model includes a pre-filtration tank 1 for initially removing large particulate impurities and suspended solids from sewage. A treatment tank 2 is provided on one side of the pre-filtration tank 1 for further treatment of the pre-filtered sewage. A fine filtration tank 3 is provided on one side of the treatment tank 2 for further removing fine particles and suspended solids from the sewage. A first pumping pipe 6 is provided inside the pre-filtration tank 1 to pump out the pre-filtered sewage. The first pumping pipe 6 is connected to a first water pump 7, which is fixed to the top of the pre-filtration tank 1. The output end of the first water pump 7 is connected to a first connecting pipe 8. One end of the first connecting pipe 8 is connected to a first inlet pipe 10 via a fixing mechanism 9. The first inlet pipe 10 is connected to the treatment tank 2. The fixing mechanism 9 includes components disposed on the first... The mounting flange 901 at one end of the connecting pipe 8 is connected to the mounting base 902 at one end of the first water inlet pipe 10. The mounting flange 901 matches the mounting base 902. The mounting flange 901 has grooves 903 on both sides. The grooves 903 have telescopic springs 904 inside. One end of the telescopic spring 904 is connected to the mounting flange 901, and the other end is connected to the locking post 905. The mounting base 902 has a locking groove 906. The locking post 905 matches the locking groove 906. The mounting flange 901 and the mounting base 902 are connected by bolts and nuts. When the mounting flange 901 is installed, the locking post 905 can automatically spring into the locking groove 906 on the mounting base 902 to form a preliminary lock. Then, with the bolts and nuts, a final lock is achieved to ensure a tight and leak-free connection. The treatment tank 2 is equipped with a second water pump 17, which is connected to a second water pump 18. The output end of the second water pump 18 is connected to a second connecting pipe 19. One end of the second connecting pipe 19 is connected to a second inlet pipe 20 via a fixing mechanism 9. The second inlet pipe 20 is connected to the fine filter tank 3. Filter screens 24 are connected to the bottom ends of the first water pump 6 and the second water pump 17. A sewage discharge pipe 28 is connected to one side of the pre-filter tank 1 and the treatment tank 2. The sewage discharge pipe 28 is connected to a sewage pump 29, and one end of the sewage pump 29 is connected to a sludge discharge pipe 30, effectively removing wastewater from the pre-filter tank 1. To remove sludge and impurities accumulated in the pre-filter box 1 and treatment box 2, and to maintain the normal operation of the system, the pre-filter box 1, treatment box 2 and fine filter box 3 are connected to both sides by fixing plates 31. The fixing plates 31 on different boxes are connected by bolts and nuts to assemble the boxes of different modules together. The pre-filter box 1, treatment box 2 and fine filter box 3 are all divided into two parts: the box body and the top cover. The top cover is connected to the box body by bolts, which makes it easy to open for inspection, maintenance or replacement of internal components. The pre-filter box 1 is equipped with an inlet pipe 32 at the top, and the fine filter box 3 is equipped with an outlet pipe 27 on one side.

[0030] like Figures 1-6As shown, an installation block 4 is connected to the inner wall of the pre-filtration box 1, and a grid 5 is connected above the installation block 4. The grid 5 has an opening for the first water pipe 6 to pass through. A handle is connected to the top of the grid 5, and a first slider 11 is provided at the bottom of the grid 5. A first groove 12 is provided inside the installation block 4, and the first slider 11 matches the first groove 12. The bottom of the first slider 11 is connected to the installation block 4 by a magnet. The double fixing method of slider and magnet facilitates disassembly and cleaning. A central shaft 13 is provided inside the treatment box 2, and a stirring rod 14 is connected to the central shaft 13. One end of the central shaft 13 passes through the treatment box 2 and is connected to the output end of the drive motor 15. The drive motor 15 is fixed to the top of the treatment box 2 and can drive the stirring rod. 14. Rotation ensures thorough mixing of chemicals and wastewater. The top of the treatment tank 2 has a dosing port 16 for adding chemical reagents (such as coagulants and flocculants) to promote pollutant aggregation and sedimentation. The fine filtration tank 3 has a fixed frame 21 inside, with second sliders 22 on both sides. The fine filtration tank 3 also has a second sliding groove 23 inside, matching the second sliders 22 and the second sliding groove 23. The fixed frame 21 contains three filter screens 24, which can be coarse, medium-efficiency, and high-efficiency filters, respectively. The coarse filter mainly intercepts large particles remaining after pre-filtration, preventing them from entering subsequent finer filtration layers. The medium-efficiency filter further removes smaller suspended particles and some colloidal substances. High-efficiency filters, such as microfiltration or ultrafiltration membranes, effectively remove bacteria, viruses, and some dissolved organic matter. Connecting blocks 25 are connected to both sides of the filter screen 24. The fixed frame 21 has a connecting groove 26 inside, with the connecting blocks 25 slidingly connected to the connecting groove 26 for easy replacement of the filter screen 24.

[0031] In practical use, when assembling several tanks, they can be pushed together and connected by bolts through the fixing plate 31 and nuts. Then, the mounting flange 901 is installed inside the mounting base 902. The locking pin 905 automatically springs into the locking groove 906 under the action of the telescopic spring 904, completing the initial locking. Finally, bolts and nuts are tightened to ensure a firm connection and good sealing, effectively preventing leakage. This completes the assembly of the equipment. When the equipment is working, the wastewater to be treated enters the pre-filter tank 1 through the inlet pipe 32 located at the top of the pre-filter tank 1. The wastewater first enters the area of ​​the bar screen 5, which intercepts large particles such as plastic bags, branches, and stones, preventing them from entering the subsequent system and causing blockages or damage. After preliminary filtration, the wastewater flows to the bottom of the pre-filter tank 1. At this time, the first water pump 7 installed at the top of the pre-filter tank 1 is started, drawing out the wastewater through the first suction pipe 6 and transporting it to the treatment tank 2 via the first connecting pipe 8. After entering the treatment tank 2, the wastewater undergoes chemical dosing and agitation treatment in this area. Operators add coagulants, flocculants, and other chemical reagents through the dosing port 16 located at the top of the treatment tank 2 to promote the coagulation of fine suspended solids and colloidal substances in the water into larger particles for easier subsequent removal. Simultaneously, the drive motor 15 rotates the central shaft 13, which in turn drives the agitator 14 mounted on it to thoroughly stir the wastewater, ensuring uniform mixing of the reagents and wastewater and improving reaction efficiency. The treated wastewater is then pumped out by the second pump 18 through the second pumping pipe 17 and sent to the fine filter box 3 through the second connecting pipe 19. It is filtered by the three-layer filter screen 24 inside the fine filter box 3 to filter suspended solids of different particle sizes, thereby improving the quality of the effluent. After filtration, it is discharged through the outlet pipe 27. During the entire treatment process, the pre-filter box 1 and the treatment box 2 are equipped with a sewage discharge pipe 28 on one side, which is connected to the sludge discharge pipe 30 through the sewage discharge pump 29. This is used to periodically discharge the sludge and impurities deposited in the box. When it is necessary to clean the bar screen 5, the top cover of the pre-filter box 1 can be removed, and the bar screen 5 can be lifted by lifting the handle. When it is necessary to replace the filter screen 24 inside the fine filter box 3, the top cover of the fine filter box 3 can be removed, and then the second sliders 22 on both sides of the fixing frame 21 can be taken out from the second slide groove 23. The entire fixing frame 21 can be lifted, and the filter screen 24 on the fixing frame 21 can be disassembled and replaced.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
