The invention relates to an integral indoor ecological circulating water culture system, belonging to the technical field of culture water biological purification. The system comprises a vinyl house, a sedimentation basin, a methane tank, a biological filter pool A, a biological filter pool B, a biological filter pool C, a water storage tank, a breeding pond A, a breeding pond B, a breeding pond C, a breeding pond D and a breeding pond E, and wherein the sedimentation basin, the biological filter pools, the water storage tank, and the breeding ponds are symmetrically arranged in the vinyl house in a straight line. A water collecting main pipe, a back-flow pipe and an aeration main pipe are sequentially arranged on two sides of the sedimentation basin, the biological filter pools, the water storage tank and the breeding ponds. After being processed by multiple steps such as automatic collection and sedimentation, filtration, and absorption and conversion by water plant and stuffing materials, the breeding water of the system enters into the water storage tank to be subjected to reoxygenation and sterilization, then the breeding water is promoted into the breeding ponds for circulation and utilization through an immersible pump, thus the production cost of indoor industrial culture is lowered, and the system has remarkable popularization and application prospect in water shortage areas in our country for developing the high-density culture.
