Abstract

The invention relates to the technical field of aquatic product aquaculture, in particular to a phycomycete water prawn circulating aquaculture system. The system comprises an aquaculture pond and a water treatment device, wherein a roof which is provided with an illumination intensity adjustable facility and covers the upside of the aquaculture pond is arranged above the aquaculture pond; the pool bottom of the aquaculture pond is gradually inclined from the periphery to the middle; a drainage port is formed in the middle of the pool bottom; an aquaculture area of the aquaculture pond is 400-1,000m<2>; the aquaculture pond is a circle or a chamfered square; the water treatment device consists of a water outlet well, a filter groove, a water return well, a circulating water pump and foam air floatation towers sequentially; the drainage port is connected with the water outlet well by a pipeline; the water outlet well is sequentially connected with the filter groove, the water return wall and the circulating water pump; the circulating water pump is connected with the foam air floatation towers by pipelines; and the foam air floatation towers are connected with tangent water distribution pipes arranged at the periphery of the aquaculture pond by pipelines. The system has the characteristics of low cost, low energy consumption, automatic purification, high yield and the like, and can be widely applied to the industry of intensive aquaculture.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to a circulating aquaculture system for prawns in an algae-bacteria water system. Background technique [0002] At present, most of the pond culture methods of seawater prawns are open. In the process of open aquaculture, the residual bait, feces and microorganisms bred by exogenous nutrients are directly discharged through the behavior of changing water, and a large number of inorganic and organic nutrients such as ammonia nitrogen, phosphate, dissolved organic carbon and organic particles It directly enters the environment in the exchange of water bodies, which will cause the deterioration of the environment of the entire aquaculture water area, and then lead to a series of major problems that limit the sustainable development of aquaculture, such as water pollution, disease breeding, hygiene and safety of aquatic products.
