[0002] In the field of water treatment, filtration devices are widely used to remove suspended solids, organic matter, and other fine particles from water to purify it. Among these, filter membranes, as key filtration elements, are often used in fine filtration processes and have a direct impact on the quality of the effluent. To ensure filtration efficiency, the operating status of the filter membrane must be monitored in real time to prevent clogging that could reduce its processing capacity.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: a multi-stage filtration and adsorption treatment device for low-pollution water, including a filter device housing 1, a filter chamber 2 inside the filter device housing 1 for accommodating a preliminary filtration component, an output pipe 3 fixedly installed on one side of the bottom end inside the filter chamber 2, one end of the output pipe 3 passing through the filter device housing 1 and extending to the outside for discharging treated water, a monitoring device housing 4 fixedly installed on the outside of the output pipe 3 for installing a water flow status monitoring component, a first rotating rod 5 rotatably installed at the bottom end inside the output pipe 3 via a bearing, an impeller 6 fixedly installed on the outside of the first rotating rod 5, when water flows through the output pipe 3, driving the impeller 6 to rotate, thereby driving the first rotating rod 5 to rotate synchronously, the top end of the first rotating rod 5 passing through the output pipe 3 and the monitoring device housing 4 and extending above them, and a rotating wheel 7 fixedly connected thereto, the operator can intuitively judge the change in water flow rate by observing the rotation speed of the rotating wheel 7, and thus assess whether the filter membrane has been blocked by biofilm.

[0020] A fixing block 8 is provided inside the filter chamber 2. One end of the fixing block 8 passes through the filter housing 1 and extends to the outside, while the other end is fixed to the inner wall of the filter chamber 2. A filter hole 9 is provided at the top of the fixing block 8 to guide water flow. A slot 10 is provided at one end of the fixing block 8 for slidably inserting a filter plate 16. A filter membrane 17 is fixedly provided at the top of the filter plate 16. The filter membrane 17 passes through the filter plate 16 and extends to the bottom to intercept small particles and organic matter in the water. To prevent water flow short circuit or to regulate flow rate, a baffle 11 is also provided at one end of the fixing block 8 via a rotating shaft. The baffle 11 is fixed in position by a locking mechanism consisting of a locking groove 12, a second rotating rod 13, a locking block 14, and a rotating block 15 to ensure that the baffle 11 remains stable at a set angle.

[0021] A first pair of connecting pipes 18 is fixedly installed at the top of the filter housing 1. The bottom end of the first pair of connecting pipes 18 passes through the filter housing 1 and communicates with the filter chamber 2. A second pair of connecting pipes 21 is threadedly connected to the upper part of the first pair of connecting pipes 18. The second pair of connecting pipes 21 is located at the bottom of the adsorption device housing 19. An adsorption chamber 20 is opened inside the adsorption device housing 19 to accommodate adsorbent material. A cover plate 32 is provided at the top of the adsorption device housing 19. A connecting block 22 is fixedly installed at the bottom end of the cover plate 32. The connecting block 22 is inserted into the adsorption chamber 20 and threadedly connected to it to form a sealed structure. A water inlet pipe 23 is fixedly installed at the top of the cover plate 32. The bottom end passes through the cover plate 32 and the docking block 22 in sequence, and the water to be treated is introduced into the adsorption chamber 20. The adsorption chamber 20 is provided with a first limiting ring 24 and a second limiting ring 28, which are used to support the first filter plate 25 and the second filter plate 29, respectively. Quartz sand 27 is filled between the top of the first filter plate 25 and the cover plate 32 to remove suspended solids in the water. Activated carbon 31 is filled between the top of the second filter plate 29 and the first filter plate 25 to adsorb heavy metal ions, odors and organic pollutants in the water. The top of the first filter plate 25 and the second filter plate 29 are provided with a first handle 26 and a second handle 30, respectively, to facilitate disassembly and replacement of the adsorption material.

[0022] In use, low-pollution water enters the adsorption chamber 20 inside the adsorption device housing 19 through the inlet pipe 23. The water flows from top to bottom through the quartz sand 27 layer filled between the cover plate 32 and the first limiting ring 24, and the activated carbon 31 layer located between the first filter plate 25 and the second filter plate 29. The quartz sand 27 has good mechanical filtration performance and can effectively remove suspended particles and some colloidal substances from the water. The activated carbon 31 achieves efficient adsorption of organic pollutants, odor components, heavy metal ions, etc. through its well-developed microporous structure, thereby completing the adsorption process. After initial purification, the water flow after adsorption treatment converges at the bottom of the adsorption chamber 20 and is discharged through the second pair of connecting pipes 21. The second pair of connecting pipes 21 is tightly connected to the first pair of connecting pipes 18 located at the top of the filter device housing 1 by means of threaded connection, ensuring that the water flow flows continuously and smoothly into the filter chamber 2. After entering the filter chamber 2, the water flow further flows through the filter hole 9 at the top of the fixing block 8 and passes through the filter membrane 17 installed in the slot 10 for final fine filtration. The filter membrane 17 can be selected with different pore size specifications according to the water quality to adapt to different treatment needs.

[0023] After treatment, the clean water is discharged from the system through the output pipe 3. During this process, the impeller 6 rotates with the water flow, driving the first rotating rod 5 connected to it to rotate synchronously, which in turn drives the rotating wheel 7 located above the monitoring device housing 4 to rotate. Operators can visually observe or measure the rotation frequency of the rotating wheel 7 with the aid of a speed measuring instrument to determine whether the current water flow speed is within the normal range. When a biofilm gradually forms on the surface of the filter membrane 17 due to long-term operation or when it is blocked by suspended solids, the water flow resistance increases, causing the overall flow velocity to decrease. At this time, the rotation speed of the rotating wheel 7 will slow down significantly, becoming an important indicator for judging the condition of the filter membrane. To ensure the stable operation of the system, operators should perform maintenance operations in a timely manner according to the rotational speed of the impeller 7, including but not limited to cleaning, replacing, or backwashing the filter membrane 17. In addition, auxiliary equipment such as differential pressure sensors or flow meters can be combined to achieve more accurate clogging warning and automatic control functions. In summary, the multi-stage filtration and adsorption treatment device provided by this utility model not only ensures efficient water purification capabilities but also has a good operation monitoring mechanism and convenient maintenance. It is suitable for various low-pollution water treatment scenarios, such as industrial wastewater reuse, urban sewage treatment, and drinking water pretreatment.

[0024] This utility model provides a multi-stage filtration and adsorption treatment device for low-pollution water, which has the advantages of reasonable structural design, high purification efficiency, stable operation and convenient maintenance. Among them, a particularly prominent beneficial effect is reflected in its real-time monitoring function of the filter membrane 17 based on the linkage structure of impeller 6 and rotor 7. Specifically, during the process of water flowing out of the output pipe 3 after treatment, the impeller 6 set inside the output pipe 3 rotates with the water flow and transmits the rotational motion to the rotor 7 above through the first rotating rod 5 fixedly connected to it. The operator can intuitively judge whether the current water flow rate is within the normal range by observing the change in the rotation speed of the rotor 7, thereby indirectly assessing whether the filter membrane 17 is blocked by biological layer or physically polluted.

[0025] Compared to traditional methods relying on electronic sensors or periodic manual sampling and testing, this structure utilizes simple mechanical transmission to achieve dynamic monitoring of the operating status of key components. It can perform preliminary early warning functions without the need for additional complex electronic control systems, effectively reducing equipment costs and maintenance difficulty. Simultaneously, this structure possesses excellent response sensitivity and stability, providing operators with timely and intuitive maintenance signals to ensure that the filter membrane 17 is always in a highly efficient working state. Furthermore, the filter membrane 17 adopts a detachable installation method using slot 10, allowing for modular replacement in conjunction with the filter plate 16. This enables rapid replacement after confirming a decline in filter membrane performance, avoiding reduced treatment efficiency or system downtime due to filter membrane 17 clogging. This structural design not only improves the overall system's operational continuity but also significantly enhances the equipment's adaptability and maintainability. In summary, this utility model, by introducing a monitoring structure composed of impeller 6, first rotating rod 5, and rotating wheel 7, combined with the replaceable slot 10 design of the filter membrane 17, achieves visualized status feedback and rapid maintenance response for the filtration process. It has good engineering application value and promotion prospects, and is particularly suitable for small and medium-sized water treatment facilities or application scenarios lacking automated control conditions.
