[0022] 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.

[0023] Example 1

[0024] As attached Figures 1 to 5 The energy-saving MBR lightweight membrane module shown includes a membrane frame 1, a primary filter frame 5 and a secondary filter frame 8. The membrane frame 1 has side plate openings 2 on both sides. The inner cavity at the center of the membrane frame 1 has a multi-stage filter installation groove 3. The inner cavities of the two sets of side plate openings 2 are each equipped with a three-dimensional flow channel mesh 4.

[0025] A primary filter frame 5 is installed inside the multi-stage filter mounting groove 3. The primary filter frame 5 has a first filter screen frame 6 inside its cavity, and an activated carbon filter screen 7 is installed inside the first filter screen frame 6. A secondary filter frame 8 is located on one side of the primary filter frame 5. The secondary filter frame 8 has a second filter screen frame 9 inside its cavity, and a microporous filter screen 10 is installed inside the second filter screen frame 9. Both the primary filter frame 5 and the secondary filter frame 8 have handles 11 at their upper ends. Magnetic strips 12 are installed at the upper and lower ends of the opposite surfaces of the first filter screen frame 6 and the second filter screen frame 9.

[0026] The membrane plate frame 1 is a hollow structure, thereby reducing the weight of the frame and achieving a lightweight structure. The three-dimensional flow channel net 4 in the two sets of side plate openings 2 has a standardizing effect on the internal flow channel, making the water flow more evenly distributed in the membrane assembly, and the bending resistance is borne by the membrane plate frame 1. The three-dimensional flow channel net 4 serves as an important supporting structure for the MBR membrane, providing a solid physical support for the membrane. During the operation of the water treatment system, the MBR membrane needs to withstand the pressure from the water flow and possible external mechanical stress. The presence of the three-dimensional flow channel net 4 enables the membrane to evenly disperse these pressures, preventing deformation or damage of the membrane due to excessive local stress. The multi-stage filtration installation slot 3 in the membrane plate frame 1 provides a limiting space for the multi-stage filtration structure. The activated carbon filter net 7 and the microporous filter net 10 together form a multi-stage filtration system. The activated carbon filter net 7 in the primary filtration frame 5 utilizes the porosity and high adsorption capacity of activated carbon to effectively remove dissolved organic matter, odor substances, and part of heavy metal ions in water, providing higher water quality purification function. The secondary filtration frame 8 works in coordination with the primary filtration frame 5. The activated carbon filter net 7 reduces the burden on the secondary filtration frame 8, allowing the microporous filter net 10 to focus more on the interception of small suspended particles. The handle 11 provides great convenience for the disassembly and installation of the primary filtration frame 5 and the secondary filtration frame 8. The operator only needs to hold the handle 11 to easily remove or insert the primary filtration frame 5 and the secondary filtration frame 8 from the multi-stage filtration installation slot 3 without the need for complex tools or equipment. This quickly adapts to the challenges brought about by different water sources and water quality changes. The magnetic strips 12 are installed on the upper and lower ends of the opposite sides of the first filter net frame 6 and the second filter net frame 9. When the first filter net frame 6 and the second filter net frame 9 are installed together, the magnetic strips 12 attract each other, allowing them to tightly fit together. The multi-stage filter net does not affect the MBR membrane on the three-dimensional flow channel net 4, but effectively supports and resists the membrane for filtration.

[0027] Example 2

[0028] Based on the embodiment 1, the scheme in embodiment 1 is further refined and introduced in detail as follows in combination with the specific working mode: Figures 1 to 5

[0029] As a preferred embodiment, the two sets of side plate openings 2 are symmetrically arranged, and the edges of the three-dimensional flow channel net 4 are connected to the inner surfaces of the side plate openings 2. Further, the two sets of symmetrically arranged side plate openings 2 correspond to the two sets of three-dimensional flow channel nets 4, ensuring that the water flow passes through in sequence. The close connection of the side plate openings 2 ensures that the water flow smoothly enters the three-dimensional flow channel net 4 from the side plate openings 2.

[0030] ​As a preferred embodiment, the upper end of the multi-stage filter mounting groove 3 is open, and the multi-stage filter mounting groove 3 is in communication with the two sets of side plate openings 2; further, the open design of the upper end of the multi-stage filter mounting groove 3 provides a direct and unobstructed channel, which facilitates the operator to easily insert or remove the primary filter frame 5 and the secondary filter frame 8, and when rapid assembly and replacement of filter screens and other components are required, complex tools are not needed, thereby improving work efficiency.

[0031] As a preferred embodiment, the primary filter frame 5 is adsorbed to the secondary filter frame 8 by the four sets of magnetic strips 12, and the primary filter frame 5 and the secondary filter frame 8 are both inserted into the multi-stage filter mounting groove 3 to be limited; further, the operator only needs to attach the primary filter frame 5 to the secondary filter frame 8, and then the four sets of magnetic strips 12 can adsorb them together, which facilitates simultaneous installation and insertion into the multi-stage filter mounting groove 3 for limiting.

[0032] As a preferred embodiment, the position of the primary filter frame 5 and the secondary filter frame 8 is changed along the multi-stage filter mounting groove 3 by adjusting the two sets of handles 11 to move linearly; further, the position of the primary filter frame 5 and the secondary filter frame 8 can be changed by adjusting the handles 11, and they can be pulled out along the multi-stage filter mounting groove 3, so that the filtering strategy and the filtering order can be flexibly adjusted according to different water quality characteristics and processing requirements.

[0033] As a preferred embodiment, the surface of the microporous filter screen 10 is arranged with a plurality of equidistantly distributed micropores, and the activated carbon filter screen 7 is symmetrically arranged with the microporous filter screen 10; further, when the microporous filter screen 10 processes water containing fine suspended impurities, the equidistantly distributed micropores can uniformly intercept on the entire filtering surface like an accurate sieve.

[0034] The working process of the utility model is as follows: firstly in the running process, the water to be processed firstly enters from the side plate openings 2 on both sides of the membrane plate frame 1, because the side plate openings 2 are symmetrically arranged and the edges of the three-dimensional flow channel net 4 installed inside are connected with the inner surface of the side plate openings 2, the water flow is uniformly and smoothly guided, and under the filtering and guiding of the three-dimensional flow channel net 4, a stable and orderly flow field is formed in the membrane plate frame 1, and the rigid structure of the three-dimensional flow channel net 4 can uniformly transmit the pressure to the entire membrane plate frame 1, so that the membrane sheet can maintain flatness and integrity in the long-term running process, and then the water flow enters the multi-stage filter mounting groove 3 area;

[0035] When the primary filter frame 5 and the secondary filter frame 8 are adsorbed and fixed by the magnetic attraction strip 12 and then inserted into the multi-stage filter installation slot 3, the water flow first flows through the activated carbon filter screen 7 in the first filter screen frame 6. The activated carbon filter screen 7 can adsorb dissolved organic matter, peculiar smell substances and part of heavy metal ions in the water by virtue of its developed pore structure and large specific surface area, thereby preliminarily purifying the water quality. Subsequently, the water flow continues to move forward and enters the microporous filter screen 10 in the second filter screen frame 9. Since the microporous filter screen 10 is arranged in equidistant distribution on the surface, it can uniformly and accurately intercept the small suspended particles and colloidal impurities remaining in the water after the treatment by the activated carbon filter screen 7, thereby further improving the clarity and purity of the water quality. When it is necessary to adjust the filtering strategy according to the change of the water quality, the position of the activated carbon filter screen 7 and the microporous filter screen 10 can be changed by adjusting the handle 11 to change the position of the primary filter frame 5 and the secondary filter frame 8, so that the activated carbon filter screen 7 and the microporous filter screen 10 can be linearly moved out or inserted into the multi-stage filter installation slot 3, and the order of the two can be exchanged to adapt to different pollutant concentrations and complete the multi-stage filtering treatment of different types of pollutants. When the treatment target changes, the overall filtering strategy can be quickly changed by enabling or disassembling the multi-stage filter structure. The above is the working principle of the energy-saving MBR lightweight membrane assembly.
