The honeycomb-shaped filtration membrane layer 3-3 is a filtration membrane provided with foot processes. The filtration membrane for filtering and purifying molecules is a square structure. The upper and lower end faces of this filtration membrane are respectively the honeycomb-shaped filtration membrane I 1 and the honeycomb-shaped filtration membrane II 3. The left and right end faces of the filtration membrane are respectively the intermediate filtration layer 2. The front and rear end faces of the filtration membrane can be respectively the connection parts of the honeycomb-shaped filtration membrane I 1 and the honeycomb-shaped filtration membrane II 3, or the front and rear end faces of the filtration membrane can be respectively structures that cannot pass any molecules.Alternatively, the intermediate filter layer 2 is a hollow structure made of a filter membrane that does not carry any electrons, and the honeycomb filter membrane I1 and the honeycomb filter membrane II3 are respectively located on the upper end surface and the lower end surface of the intermediate filter layer 2, and the side wall of the intermediate filter layer 2 is the entrance.

Honeycomb filter membrane layer Ⅰ1-1, honeycomb filter membrane layer Ⅱ1-2 and honeycomb filter membrane layer Ⅲ1-3 are the same membranes, but the shapes of the filter holes are different. Honeycomb filter membrane layer Ⅰ1-1, honeycomb filter membrane layer Ⅱ1-2 and honeycomb filter membrane layer Ⅲ1-3 are synthesized into an integral filter membrane. Similarly, honeycomb filter membrane layer Ⅳ3-1, honeycomb filter membrane layer Ⅴ3-2 and honeycomb filter membrane layer Ⅵ3-3 are the same membranes, but the shapes of the filter holes are different.

The electronic polarity on the filter membrane can be found in the material it comes with, or it can be coated by a process. Fibers, nano or graphene materials can be processed to carry positrons or electrons. Therefore, the honeycomb filter membrane Ⅰ1 and the honeycomb filter membrane Ⅱ3 can be coated with electrons on the material through a process or made into a membrane with electronic polarity through a process.

[0016] Specific embodiment: A filter membrane for filtering and purifying molecules, mainly composed of a honeycomb filter membrane Ⅰ1, a honeycomb filter membrane layer Ⅰ1-1, a honeycomb filter membrane layer Ⅱ1-2, a honeycomb filter membrane layer Ⅲ1-3, a honeycomb filter membrane Ⅱ3, a honeycomb filter membrane layer Ⅳ3-1, a honeycomb filter membrane layer Ⅴ3-2, a honeycomb filter membrane layer 3-3, an intermediate filter layer 2 and a void area 4. All the filter membrane layers are designed as a whole, and can be designed into different shapes such as a circular or square honeycomb. The neutral filter layer 2 and the honeycomb filter membrane Ⅰ1 and the honeycomb filter membrane Ⅱ3 are made into an integral filter membrane for filtering and purifying molecules. The integral filter membrane is designed with a void area 4 in the middle, and the outside is designed as an external layer that cannot pass any molecules. After the molecular substances pass through the neutral filter layer 2 and enter the void area 4, they are divided into positive and negative electrons and enter the honeycomb filter membrane Ⅰ1 and the honeycomb filter membrane Ⅱ3 respectively, and are filtered out from the honeycomb filter membrane Ⅰ1 and the honeycomb filter membrane Ⅱ3 to achieve the purpose of purification and filtration. Thus, a filter membrane assembly 5 for filtering and purifying molecules is designed.

[0017] The honeycomb-shaped filter membrane Ⅰ1 is a membrane coated with a positive charge. The membrane can be made of fibers, nano materials, or graphene materials. The structure of the honeycomb-shaped filter membrane layer Ⅰ1-1 is designed as a spiral filter membrane, and spiral filter membrane pores (filtering pores) are provided on the honeycomb-shaped filter membrane layer Ⅰ1-1. The positive charge coated on the honeycomb-shaped filter membrane layer Ⅰ1-1 plays a role of charge barrier; the size of the filter membrane pores is equivalent to a mechanical barrier, which can prevent macromolecules larger than the diameter of the filter membrane pores from passing through. The structure of the honeycomb-shaped filter membrane layer Ⅱ1-2 is designed as a microfiber network structure, and the positive charge carried on the honeycomb-shaped filter membrane layer Ⅱ1-2 plays a role of charge barrier; the size of the filter membrane pores on the fiber network structure is equivalent to a mechanical barrier, which can prevent macromolecules larger than the diameter of the fiber network structure pores from passing through. The structure of the honeycomb-shaped filter membrane layer Ⅲ1-3 is designed to have foot processes, and gaps are formed between the interlaced foot processes. There is a gap diaphragm for filtering on the gap. There are pores with a diameter on the gap diaphragm, which can prevent macromolecules 5 filtered out by the inner and middle layers from passing through, and it is the last barrier for filtration. These three layers together constitute the filter membrane layer 1.

[0018] The intermediate filter layer 2 is a filter layer without any electrons. The filter membrane on the intermediate filter layer 2 can be designed as a honeycomb shape, and the filter pores on the intermediate filter layer 2 can be designed as spiral mechanical pores. Under the action of pressure and flow rate, the flow rate is faster. There is a gap area 4 between the intermediate filter layer 2 and the honeycomb-shaped filter membrane Ⅰ1 and the honeycomb-shaped filter membrane Ⅱ3. When the mixed molecules filter through the neutral layer of the intermediate filter layer 2 and enter the gap area 4, the intermediate filter layer 2 prevents macromolecules 5 from passing through, enabling small molecule 6 substances to enter the gap area 4 through the spiral mechanical pores, and then passing through the charged honeycomb-shaped filter membrane Ⅰ1 and the honeycomb-shaped filter membrane Ⅱ3 for filtration respectively to obtain positively charged substances and negatively charged substances.

[0019] The honeycomb-shaped filter membrane Ⅱ3 is a membrane coated with a negative charge. The membrane can be made of fibers, nano materials, or graphene materials. The structure of the honeycomb-shaped filter membrane layer Ⅳ3-1 is designed as a spiral filter membrane, and spiral filter membrane pores are provided on the honeycomb-shaped filter membrane layer Ⅳ3-1. The negative charge carried on the honeycomb-shaped filter membrane layer Ⅳ3-1 plays a role of charge barrier; the size of the filter membrane pores is equivalent to a mechanical barrier, which can prevent macromolecules larger than the diameter of the filter membrane pores from passing through. The structure of the honeycomb-shaped filter membrane layer Ⅴ3-2 can be designed as a microfiber network structure, and the negative charge carried on the honeycomb-shaped filter membrane layer Ⅴ3-2 plays a role of charge barrier; the size of the fiber network structure pores is equivalent to a mechanical barrier, which can prevent macromolecules larger than the diameter of the fiber network structure pores from passing through. The structure of the honeycomb-shaped filter membrane layer 3-3 is designed to have foot processes, and gaps are formed between the interlaced foot processes. There is a gap diaphragm for filtering on the gap. There are pores with a diameter on the gap diaphragm, which can prevent macromolecules filtered out by the inner and middle layers from passing through, and it is the last barrier for filtration. These three layers together constitute the filter membrane layer 3.

[0020] During installation, a filtration membrane for filtering and purifying molecules is set on the equipment pipeline for purifying and filtering molecules. Under the conditions of set pressure, flow rate, resistance, chemical, physical and other factors, the mixed molecules enter the filtration membrane 5 for filtering and purifying molecules. The mixed molecules enter from one end of the inlet of the neutral layer filtration layer 2. When passing through the neutral layer filtration layer 2, the neutral layer filtration layer 2 prevents macromolecules from passing through, enabling small molecule substances and residual macromolecules to enter the void area 4 through the spiral mechanical pores. The charged small molecules are respectively filtered out from the honeycomb-shaped filtration membrane I 1 and the honeycomb-shaped filtration membrane II 3, and the neutral molecules are filtered out from the other end of the neutral filtration layer 2, achieving the purpose of purification and filtration.

[0021] Since each layer of the honeycomb-shaped filtration membrane II 3 contains many negatively charged substances, the permeability of the honeycomb-shaped filtration membrane II 3 also depends on the charge carried by the substance to be filtered. These negatively charged substances repel negatively charged molecules and restrict their filtration. Even if the effective radius of the molecule is smaller than the pore size of the filter, due to its negative charge, it is difficult to pass through the filtration membrane. When the effective radii are the same, positively charged substances are more permeable than negatively charged substances. Because the honeycomb-shaped filtration membrane II 3 is mainly negatively charged, they can repel negatively charged substances. In the three-layer structure of the honeycomb-shaped filtration membrane II 3, each layer is designed with charged substances covering it. These negatively charged groups can prevent substances with the same charge from passing through, playing the role of an electrochemical barrier.

[0022] Since each layer of the honeycomb-shaped filtration membrane I 1 contains many positively charged substances, the permeability of the honeycomb-shaped filtration membrane I 1 also depends on the charge carried by the substance to be filtered. These positively charged substances repel positively charged molecules and restrict their filtration. Even if the effective radius of the molecule is smaller than the pore size of the filter, due to its positive charge, it is difficult to pass through the filtration membrane. When the effective radii are the same, negatively charged substances are more permeable than positively charged substances. Because the honeycomb-shaped filtration membrane I 1 is mainly positively charged, they can repel positively charged substances. In the three-layer structure of the honeycomb-shaped filtration membrane I 1, each layer is designed with charged substances covering it. These positively charged groups can prevent substances with the same charge from passing through, playing the role of an electrochemical barrier.
