Algae water system shrimp recirculating aquaculture system

Abstract

The present invention relates to the technical field of aquatic product cultivation, in particular to a prawn recirculating aquaculture system in an algae-bacteria water system, comprising: a culture pond, a facility with adjustable light intensity is arranged above the culture pond and covers the roof above the culture pond, and the pond of the culture pond The bottom gradually inclines from the surroundings to the center and there is a drainage port in the center of the bottom of the pool. The breeding area of ​​the breeding pond is 400-1000m2, and the breeding pond is a round or chamfered square; the water treatment device consists of a water outlet well, a filter tank, It is composed of a return well, a circulating water pump and a foam air flotation tower. The outlet is connected to the water outlet well through a pipeline, and the water outlet well is connected to the filter tank, the return water well and the circulating water pump in turn. The air flotation tower is connected with the tangential water distribution pipes arranged around the culture pond through pipelines. The invention has the characteristics of low cost, low energy consumption, self-purification, high output and the like, and can be widely used in intensive aquaculture industry.

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.

AI Technical Summary

Problems solved by technology

The current intensive recirculating aquaculture system mainly uses microfiltration to remove the former and biofiltration to remove the latter. This treatment method is used by the flow method, but it also shows limitations to the effectiveness of the system.

First of all, it occupies a certain proportion of the production environment; second, the efficiency of purification treatment fluctuates significantly; third, it needs to consume energy, equipment and manual maintenance and control
