[0017] 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.

[0018] Please see Figures 1-5 One embodiment provided by this utility model: A greywater reuse ultrafiltration device, the grid filter plate 3, the drum filter box 5, the electric telescopic rod 9 and the ultrafiltration membrane treatment cylinder 14 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. It includes a collection frame 1, a pretreatment component is installed inside the collection frame 1, and a dispensing component is installed on the top surface of the pretreatment component. The pretreatment component includes a support frame 2, which is installed on the inner side wall of the collection frame 1. A grid filter plate 3 is installed on the top surface of the support frame 2. A first conveying pipe 4 is installed on the right side of the grid filter plate 3. A rotary drum filter box 5 is installed on the right side of the first conveying pipe 4. The dispensing assembly includes a sliding frame 6, which is installed on the upper surface of the rotary drum filter box 5. Firstly, rainwater is collected by the collection frame 1. Then, larger impurities are blocked by the grid filter plate 3, preventing them from entering the subsequent filtration process with the rainwater. The grid filter plate 3 is supported by the support frame 2, allowing it to be removed for cleaning later. Rainwater is then transported into the rotary drum filter box 5 via the collection frame 1 and the first conveying pipe 4, where it undergoes precise filtration without clogging, resulting in a good overall filtration effect. This setup, through the pretreatment assembly, performs preliminary and precise filtration of impurities in the rainwater.

[0019] The rotary drum filter box 5 has a sliding groove 7 inside, and a feeding frame 8 is slidably installed inside the sliding groove 7. A valve body is installed on the right side of the feeding frame 8. An electric telescopic rod 9 is installed on the back of the feeding frame 8 and is mounted on the inner wall of the sliding frame 6. An inclined block 12 is installed on the lower surface of the feeding frame 8. When adding coagulant, the coagulant is first placed inside the feeding frame 8. Then, the discharge speed of the feeding frame 8 can be controlled by the valve body on the outer surface of the feeding frame 8. The electric telescopic rod 9 can drive the feeding frame 8 to move back and forth inside the sliding groove 7. At this time, the feeding frame 8 can evenly distribute the coagulant on the top surface of the rotary drum filter box 5, and the inclined block 12 can guide the added coagulant.

[0020] A guide plate 10, shaped like an inverted "V," is installed on the inner wall of the drum filter box 5. The guide plate 10 has perforations 11 inside. A second conveying pipe 13 is installed on the front surface of the drum filter box 5. An ultrafiltration membrane treatment cartridge 14 is installed at the end of the second conveying pipe 13 furthest from the drum filter box 5. A third conveying pipe 15 is installed on the right side of the ultrafiltration membrane treatment cartridge 14. A water storage tank 16 is installed at the end of the third conveying pipe 15 furthest from the ultrafiltration membrane treatment cartridge 14. A fourth conveying pipe 17 is installed on the back of the water storage tank 16, and an ultraviolet disinfection lamp is installed inside the water storage tank 16. After addition, the shape of the guide plate 10 guides and transports the coagulant. The coagulant also enters the rotary drum filter box 5 through the leak 11, ensuring even distribution. Adding the coagulant removes colloidal substances from the water and reduces turbidity. The rainwater is then transported through the second conveying pipe 13 to the ultrafiltration membrane treatment cylinder 14 for ultrafiltration treatment. The treated water is then transported through the third conveying pipe 15 to the storage tank 16 for on-site storage, resulting in good overall storage performance. The fourth conveying pipe 17 enables rainwater recycling, such as for greening irrigation, road washing, and landscape water replenishment, achieving efficient rainwater recovery and safe reuse. This method is suitable for urban areas, industrial zones, and building complexes.

[0021] Working principle: When the staff uses this device, first connect the device to an external power source to provide power support. Rainwater can be collected through the collection frame 1, and larger impurities can be blocked through the grid filter plate 3. This overall blocking of larger impurities prevents impurities from entering the subsequent filtration process with the rainwater. The grid filter plate 3 is supported by the support frame 2. Afterwards, the grid filter plate 3 can be removed for cleaning. Then, the rainwater is transported to the inside of the rotary drum filter box 5 through the collection frame 1 and the first conveying pipe 4. The rotary drum filter box 5 can then perform precise filtration and is not easy to clog. When adding coagulant, the coagulant is first placed inside the feeding frame 8. Then, the discharge speed of the feeding frame 8 can be controlled by the valve body on the outer surface of the feeding frame 8. Then, the electric telescopic rod 9 can drive the feeding frame 8 to move back and forth inside the sliding groove 7. At this time, the feeding frame 8 can evenly add coagulant to the top surface of the rotary drum filter box 5. After addition, the shape of the guide plate 10 can guide and transport the coagulant. At this time, the coagulant will also enter the interior of the rotary drum filter box 5 through the leakage hole 11, so that the coagulant can be evenly added. By adding coagulant, colloidal substances in the water can be removed and turbidity reduced. Then, the rainwater is transported to the interior of the ultrafiltration membrane treatment cylinder 14 through the second conveying pipe 13 for ultrafiltration membrane treatment. Then, the treated water is transported to the interior of the water storage tank 16 through the third conveying pipe 15 for on-site storage and treatment. The above is the working principle of this utility model.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
