Prawn industrial culture system combining circulating water and biofloc

Abstract

The invention discloses a prawn industrial culture system combining circulating water and biofloc, and relates to the technical field of prawn culture. The system comprises a culture subsystem, a water treatment subsystem, and an intelligent control subsystem; the culture subsystem comprises a culture pond, an inflating device, a heating device, a dirt collecting area and a water inlet and outletpipeline; the water treatment subsystem comprises a solid-liquid separation device, a biological filter, a protein separator, a disinfection tank, a reservoir, a water pump and a pipeline; and the intelligent control subsystem comprises a water quality monitoring and automatic control unit, a base central control unit, a central management unit, a big data platform and a mobile terminal. The biofloc breeding, water treatment and monitoring parts involved in the system are integrated to form a set of facility-based ecological culture system with self-purification capability for prawns, the water space can be effectively utilized, the facility utilization degree is improved, the breeding controllability is improved, pollutant discharge and disease propagation are reduced, and good ecologicalbenefits are obtained; and the influence on factors such as regions and seasons can be avoided, multi-season annual output is achieved, the yield per unit area is high, and the quality is good.

Description

technical field

[0001] The invention belongs to the technical field of prawn cultivation, and in particular relates to a prawn industrial cultivation system in which circulating water and biological flocs are combined. Background technique

[0002] At present, there are disadvantages in domestic prawn farming, such as: seasonal restrictions, regional restrictions, large discharges of polluted water sources to ensure survival rates, drug abuse, etc. At the same time as the industry develops, problems are constantly exposed. Restricted by factors such as diseases and factor price increases, especially the epidemics caused by various bacteria and viruses continue to affect my country's shrimp farming industry, the total output has dropped sharply, and the contradiction between supply and demand is prominent. The success rate of the traditional breeding mode has been as low as 30%, and the total output has dropped sharply. The reason is that the breeding density is too high and...
