Cellular totally-closed recirculating aquaculture system device

Abstract

The invention discloses a cellular totally-closed recirculating aquaculture system device which is an organic fish and shrimp cultivation mode of material complete cycle and energy cascade flow, wherein material complete cycle and energy cascade flow are finished by coupling of plant photosynthesis and fish and shrimp respiratory action; a suitable environment is respectively provided for photosynthetic bacteria, monodus subterraneus, artemia and fish and shrimps by a three-dimensional multi-layer hierarchical transmitting pipeline system; illumination, temperature dissolved oxygen and pH value of a nutrient salt carbon dioxide are regulated and controlled; sunlight energy is used for driving bacillus-algae photosynthesis to convert all wastes into food organisms; bacteria and algae absorb low molecular weight organic matters to grow; the artemia takes in bacteria and algae; the fish and shrimps take in the artemia; the metabolic waste is reutilized by the bacteria and algae to form the closed material complete cycle; the bacteria and algae are synthesized into bacteria and algae protein by carbon dioxide low molecular weight organic matters as a carbon source, ammonia nitrogen nitrite and nitrate as nitrogen sources, and phosphate silicate and the like as nutrient salts; the bacteria and algae protein is transformed into animal protein by the artemia; and the animal protein is transformed into fish and shrimp products by the fish and shrimps, so that energy cascade flow is achieved.

AI Technical Summary

Problems solved by technology

The second is suspended particulate matter, which can not only directly affect the health of fish and shrimp, but also increase the burden on biological filters

The third is organic matter, whose degradation process consumes oxygen

The microfilter has the function of automatically cleaning the screen surface, which can meet the continuous operation requirements of the system. The disadvantage is that the particulate matter is easy to cause secondary crushing during the operation process, and the filter screen is easily worn out by the impact of backwash water flow, and the equipment cost is relatively high.

The disadvantage is that it cannot effectively solve the problem of automatic cleaning of the curved screen surface. When the breeding load is high, it is even necessary to manually clean the screen surface once an hour.

Because the main energy source in the system, solar energy, is free, and most of the consumable raw materials such as carbon dioxide, water, and nutrients are also almost free. Only technology, electricity, and some necessary materials need to be spent, and some Seedling fee, feed fee and labor fee
