Circulating water treatment device for industrial culture

Abstract

The invention discloses a circulating water treatment device for industrial culture. The circulating water treatment device comprises a solid-liquid separation tank, an ammonia nitrogen treatment tank, a foam separation tank, an ultraviolet sterilization device and a culture tank which are sequentially connected to form a loop, wherein the tank bottom of the solid-liquid separation tank body of the solid-liquid separation tank inclines to one side, and a drainage pipe is arranged near the bottom; aeration disks are evenly distributed on the tank bottom of the solid-liquid separation tank body; solid-liquid separation disks which are distributed at intervals and arranged in an inclined manner are arranged above the aeration disks; dense holes are evenly distributed at the lower sides of the solid-liquid separation disks; and the solid-liquid separation disks are further connected with a solid-liquid separation water outlet pipe. The circulating water treatment device disclosed by the invention has the advantages of low water change quantity, favorable water treatment effect, low operating cost, low manufacturing cost, high stability, high culture density and good disease control effect, and can control the ammonia nitrogen treatment scale as required.

Description

technical field [0001] The invention relates to an indoor circulating aquaculture system, in particular to a circulating water treatment device for industrialized aquaculture. 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 economical indoor ...
