[0002] As we all know, water treatment refers to the process of purifying and improving water sources through various technical means such as physical, chemical and biological methods. The purpose is to remove pollutants, pathogens and impurities in the water so that the water meets specific safety and hygiene standards, thereby meeting the needs of different uses such as drinking, industry, agricultural irrigation and ecological environment. Usually, nanofiltration components are required in the water treatment process, which can effectively remove harmful substances and impurities in the water, improve water quality and adapt to various application scenarios.

[0003] However, in traditional nanofiltration components used for environmental water treatment, the sealing and connection between the filter element and the membrane housing are usually achieved by gluing or welding. While this design ensures the sealing performance of the system, it also makes the removal of the filter element more difficult. The strong seal may cause damage to the filter element or membrane housing during removal. Therefore, technical improvements are urgently needed. Utility Model Content

[0035] Compared with the existing nanofiltration components for environmental water treatment, when this nanofiltration component for environmental water treatment is used, it can simultaneously accommodate multiple filter cartridges 22 through multiple storage tanks 2, so that the equipment can flexibly configure the number of filter cartridges 22 according to actual needs, thereby improving the treatment efficiency, adapting to the treatment requirements of different water qualities, and having high practical performance.

[0036] The two sides of the outer wall of the main tube 1 are respectively fixedly connected with the mounting head 11 and the mounting head 2 12, which are convenient for installation to the desired position. The mounting head 11 and the mounting head 2 12 are respectively provided with a liquid inlet hole 13 and a liquid outlet hole 14 in the middle of the outer wall of one side away from the center of the main tube 1. The liquid inlet hole 13 and the liquid outlet hole 14 facilitate the entry and outflow of liquid. The support layer 23 is made of ceramic material, the membrane layer 24 is made of polyamide material, and the inner core layer 25 is made of polyethersulfone material. The ceramic material has the characteristics of high strength, corrosion resistance, high temperature resistance, etc., and the polyamide The membrane layer 24 has good separation performance and can effectively remove divalent ions and organic matter in water. The polyethersulfone material can increase water flux, reduce membrane pollution, and enhance the adhesion between the membrane and the support layer 23.
