The invention relates to an aquaculture system, in particular to a high-density litopenaeus vannamei ecological engineered healthy breading system. An ecological engineered litopenaeus vannamei breeding facility system is characterized in that: a plastic-covered tunnel (5) which takes a metal rod as a bracket and is covered by a plastic film is arranged above a breeding pool (7), a biological cleaning pool (1), and a biochemical treating pool (2); the breeding pool (7) is spaced by water guide walls (6) in parallel arrangement to form an S-shaped annular flow channel; an outlet of the annularflow channel is communicated with inlets of the biological cleaning pool (1) and the biochemical treating pool (2); the biological cleaning pool (1) and the biochemical treating pool (2) can be opened at the same time, so that water can flow through the biological cleaning pool (1) and the biochemical treating pool (2); or one of the two is opened, and the water just flows through one of the two,and the flow rate of the two is adjustable; the outlets of the biological cleaning pool (1) and the biochemical treating pool (2) are communicated with an air-floating purifying device (3); and an outlet of the air-floating purifying device (3) is communicated with an inlet of the annular flow channel of the breeding pool (7) through a flow device (4). The system provides a good environment and agood condition for the litopenaeus vannamei, saves water resource and energy resource, and is also environmentally-friendly.
