Double-circulation zero-emission healthy breeding system

The invention discloses a double-circulation zero-emission healthy breeding system which can reduce waste of water resources and save energy. The double-circulation zero-emission healthy breeding system comprises an external circulation system, wherein the external circulation system comprises a water inlet ditch, a breeding pool, a water draining ditch, an ecological purifying pool and an ecological ditch, wherein the water inlet ditch, the breeding pool, the water draining ditch, the ecological purifying pool and the ecological ditch are connected in sequence, and the water inlet ditch and the ecological ditch are connected into the external circulation system. The double-circulation zero-emission healthy breeding system is characterized by also comprising an internal circulation system, wherein the internal circulation system comprises a breeding pool in the external circulation system and an active filtering chamber connected with the breeding pool into the circulation system. Thedouble-circulation zero-emission healthy breeding system has the advantages of solving the water quality problem caused by feeding through external circulation, removing impurities in water through the internal circulation system, realizing a large amount of circulating water and a small amount of changed water, enabling the ecological environment of the breeding water to be small, and the like.
