1. a preparation method for reverse osmosis membrane assembly, is characterized in that, comprising:

  • S1, provide central tube, by the girth n decile of the outline of described central tube and at each Along ent place mark in the circumference of described central tube;

    S2, provide n pure water selvage guide, pure water selvage guide described in one of them is connected with any one Along ent of described central tube;

    S3, provide n the filtration members be made up of reverse osmosis membrane and water inlet filter;

    S4, described central tube to be reeled from one end of a described pure water selvage guide to direction, other end place, and on this pure water selvage guide, a filtration members is inserted in winding process, when pure water selvage guide described in this is wound to the next Along ent adjacent in a roll-up direction with any one Along ent described, pure water selvage guide described in another is inserted between pure water selvage guide and described central tube described in this, continue the described central tube of winding, and on another pure water selvage guide described, insert a filtration members in winding process;

    S5, repetition step S4, until n pure water selvage guide is wound on described central tube completely, completes volume film, obtain reverse osmosis membrane assembly.
