Multiple-effect super-intensification circulating breeding device

Abstract

The invention discloses a multiple-effect super-intensification circulating breeding device which comprises a solid-liquid separation pool, an ammonia nitrogen treatment pool, a foam separation pool, an ultraviolet sterilization device and a culture pond which are sequentially connected to form a loop, wherein the pool bottom of a solid-liquid separation pool body of the solid-liquid separation pool is inclined to one side, and a blow-off pipe is close to the bottom; the blow-off pipe is connected with a breeding waste treatment device; an aeration disc is distributed at the pool bottom of the solid-liquid separation pool body; solid-liquid separation discs which are arranged at intervals and are obliquely arranged are arranged above the aeration disc; dense holes are uniformly distributed on the lower side of the solid-liquid separation disc; the solid-liquid separation disc is connected with a solid-liquid separation water outlet pipe; and the solid wastes finally precipitate to the position near the blow-off pipe and are conveyed to the breeding waste treatment device through the blow-off pipe. The multiple-effect super-intensification circulating breeding device has the advantages of small water change amount, good water treatment effect, low operating cost, low construction cost, high stability, high breeding density, good disease control effect, environment friendliness and capabilities of controlling the ammonia nitrogen treatment scale according to the needs and effectively utilizing the breeding wastes.

Description

technical field [0001] The invention relates to an inland multifunctional circulating aquaculture system, in particular to a multi-effect super-intensive circulating aquaculture device. Background technique [0002] In recent years, my country's aquaculture industry has developed rapidly, and the traditional extensive farming methods can no longer meet the needs of aquaculture development. 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 by adopting the industrialized recirculating aquaculture system. 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 economic...
