Membrane group of overclocking vibration separating device

The utility model discloses a membrane group of an overclocking vibration separating device, which comprises an upper clamping plate, a lower clamping plate, a water producing pipe and at least one a filtering membrane unit which is clamped and fixed between the upper clamping plate and the lower clamping plate, wherein the upper clamping plate is provided with a first raw water input port and a second raw water input port, and the lower clamping plate is provided with two concentrated solution output ports; the filtering membrane unit comprises a first standard membrane piece, a second standard membrane piece, a third standard membrane piece and a fourth standard membrane piece which are overlapped together from bottom to top; therefore, the first, second, third and fourth standard membrane pieces are overlapped to form the filtering membrane unit, the first and third standard membrane pieces are matched and utilized to be as double-hole standard membrane pieces, and the second and fourth standard membrane pieces are matched and utilized as single-hole standard membrane pieces, so that concentrated solution can flow in the membrane group in an S shape, effective filtering area of a membrane in unit space can be enlarged, and sewage processing capability can be expanded more easily.
