The utility model relates to a pollution discharging and circular jetting mechanism, in particular to a pollution discharging and circular jetting mechanism for penaeus vannamei. The pollution discharging and circular jetting mechanism for penaeus vannamei comprises a pond, a first-stage culture pond, a second-stage culture pond and a third-stage culture pond, pollution discharging pipes are arranged at the bottom of the first-stage culture pond, the bottom of the second-stage culture pond and the bottom of the third-stage culture pond, the pollution discharging pipes are communicated with a settling pond in the pond, the settling pond is communicated with a filtering pond, the filtering pond is communicated with a purification pond, the purification pond is communicated with a purification discharging pond, the purification discharging pond is communicated with a purification circulation non-discharging pond, and the purification circulation non-discharging pond is arranged above the pond surface of the third-stage culture pond. The pollution discharging and circular jetting mechanism for penaeus vannamei is compact and reasonable in culture structure, culture of multiple crops within one year and comprehensive cyclic utilization are achieved, the culture cost is lowered, and the quality of penaeus vannamei is improved.
