Abstract

The invention discloses a low-ammonia-nitrogen super-intensive aquiculture system. The low-ammonia-nitrogen super-intensive aquiculture system comprises an oxidation tower connected with an aquiculture container, wherein the aquiculture container is a cylindrical aquiculture tank, and funnel-shaped partition layers dividing the aquiculture tank into inner cavities of the same size or different sizes are arranged in the aquiculture tank. An electric control drainage valve is arranged at the bottom of each partition plate and connected with a drainage pipe arranged on the lateral surface of the aquiculture tank through a drainage branch pipe. An air inflation branch pipe is further arranged in the aquiculture tank and connected with a rotary oxygenation device. The air inflation branch pipe is further connected with an air inflation pump through the air inflation pipe. An inlet water overflowing branch pipe is arranged on the lateral surface of the aquiculture tank in a penetrating mode and connected with an inlet water overflowing pipe. The drainage pipe, the inlet water overflowing pipe, a water inlet end of the oxidation tower and a water outlet end of the oxidation tower are connected through a four-way valve, the oxidation tower is connected with an ozone generator, and the air inflation pump is connected with the ozone generator. The low-ammonia-nitrogen super-intensive aquiculture system has the advantages of being low in cost, high in utilization rate of water resources, good in oxygenation effect, convenient to manage, and safe and reliable. In addition, by means of the low-ammonia-nitrogen super-intensive aquiculture system, the occupied land is reduced.
