Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 - 3The utility model provides a technical solution: a nanofiltration membrane assembly for industrial wastewater treatment, comprising a shell 1, a first sealing gasket 2 fixedly connected to the bottom of the shell 1, a liquid inlet 6 is opened inside the first sealing gasket 2, a fixed guide rail 3 is fixedly connected to the inner wall of the shell 1, a nanofiltration membrane body 4 is movably connected to the interior of the shell 1, a central tube 5 is provided inside the nanofiltration membrane body 4, an alignment block 7 is fixedly connected to the bottom outer wall of the nanofiltration membrane body 4, a sealing cover 8 is movably connected to the top of the shell 1, and a second sealing gasket 9 is fixedly connected to the inner wall of the sealing cover 8. The arrangement of the shell 1, the first sealing gasket 2, the fixed guide rail 3, the nanofiltration membrane body 4, the central tube 5, the liquid inlet 6, the alignment block 7, the sealing cover 8 and the second sealing gasket 9 facilitates alignment during installation, thereby improving the stability of installation, solving the problem of easy shaking and tilting during installation, further improving the convenience of installation, and thus facilitating subsequent maintenance and cleaning, meeting people's work needs.

[0020] Furthermore, the first sealing gasket 2 is distributed in an "I" shape, and the first sealing gasket 2 is connected to the bottom wall of the shell 1 through-through, which facilitates the liquid inlet operation.

[0021] Furthermore, the fixed guide rails 3 are distributed in a concave shape, and are distributed at equal angles along the axial center line of the housing 1, which facilitates guidance.

[0022] Furthermore, the central tube 5 is connected to the sealing cover 8 through the second sealing gasket 9, and the second sealing gasket 9 is distributed in an "I" shape, which facilitates sealing.
