Low-ammonia-nitrogen super-intensive aquiculture system

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.

Description

technical field [0001] The invention relates to a complete set of industrial high-density breeding equipment, in particular to a low-ammonia nitrogen super-intensive breeding system. Background technique [0002] It is an inevitable trend to replace the traditional extensive aquaculture method with the advantages of water saving, environmental protection, controllable water quality, and production not affected by climatic conditions. However, the current domestic industrialized recirculating aquaculture system directly leads to high production costs due to its large energy consumption, high maintenance costs, and short service life, which is not conducive to promotion in vast areas of our country. Therefore, the efficient and economical indoor recirculating aquaculture system is favored and valued by farmers, and has become a culture system that is currently being researched and developed. However, although many units and individuals are currently devoting themselves to the...
