It should be understood that the specific embodiments described herein are merely illustrative of the present application and do not limit the scope of the actual protection.

Well-known manufacturing methods, control procedures, component dimensions, material compositions, pipe arrangements, etc., have not been described in detail since they are readily understood by those of ordinary skill in the art, in order to avoid obscuring the present invention. Technical solutions between various embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory, contradictory or impossible to realize, such a combination of technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

Fig. 1 is a perspective view of an embodiment of the present invention, and referring to fig. 1, an embodiment of the present invention provides a double water discharge type structure, which includes a cylindrical filter material 100 and a central tube 200 located in a hollow portion of the filter material 100 as a main structure of a membrane element. The central tube 200 is provided with water through holes, and water filtered by the filter material 100 can enter the central tube 200 through the water through holes.

Referring to fig. 2, a center tube 200 includes a nanofiltration conduit 210 and an RO membrane conduit 220, forming a combined center tube structure. A waterproof membrane 150 is disposed between the nanofiltration conduit 210 and the RO membrane conduit 220. The nanofiltration membrane 110, the filter mesh sheet 130 and the filter cloth sheet 140 are arranged outside the nanofiltration conduit 210.
