CONSTITUTION: In the dewatering equipment including a sludge receiver(10), a sludge feeder(20), a dewater reinforcing device(30), a solid-liquid separation membrane(40), a cake discharge guide(50), a cake separator(60), a separation membrane transfer device(70), primary and secondary cleaners(80,90), a dewatering device(100), the dewatering method comprises the steps of putting sludge on the surface of solid-liquid separation membrane; dewatering sludge by vacuum sucking water contained in sludge through dewatering holes of solid-liquid separation membrane(40); exfoliating the cake from solid liquid separation membrane.
