The invention relates to a rotating disc type micro-grid assembly for a backwash-free dynamic membrane. The rotating disc type micro-grid assembly comprises a circular-disc shaped filter tank, wherein the interior of the filter tank is a micro-grid cavity; the rotating disc type micro-grid assembly is characterized in that a micro-grid base material is an outer micro-grid; the filter tank is an outer filter tank; a central water outlet pipe perpendicular to a disc surface of the outer filter tank is arranged on a circle center part of the outer filter tank; a water outlet rotating disc which is matched with the central water outlet pipe in a sliding mode is sleeved on the central water outlet pipe; clamping discs which are fixedly connected with the central water outlet pipe and are fixedon two sides of the outer micro-grid are respectively sleeved on two sides of the water outlet rotating disc; a circular-disc shaped inner filter tank which is connected with the water outlet rotating disc is arranged in the
