The invention discloses a spiral zero-discharge litopenaeus-vannamei breeding system. The spiral zero-discharge litopenaeus-vannamei breeding system is composed of a first pond (1), a first separating net (2), a second pond (3), a second separating net (4), a third pond (5), a flow stopping weir (7), a settling pond (8), an overflow weir (9), a purifying pond (10), purifying plants (11), a permeable weir (12) and an air-lifting backflow device (13). The air-lifting backflow device (13) is composed of a backflow pipe (14), an ultraviolet lamp (16), an aeration disc (17), a mud collecting trough (18), a mud discharging valve (19) and a flow lifting pipe (20). The first pond (1), the second pond (3) and the third pond (5) are of a whole structure, the bottom of the whole structure is inclined from the initial end of the first pond (1) to the tail end of the third pond (5), and the slant slope is 4%. The spiral zero-discharge litopenaeus-vannamei breeding system has the advantages that high-density pond separating breeding of litopenaeus vannamei in different breeding stages is achieved, and breeding management is facilitated; water purifying capacity is high; the structure is compact, and occupied land is saved.
