Description

Intelligent cultivation seawater circulating system and use method thereof
Technical Field

Background
The invention relates to a technology for treating, purifying and managing mariculture and improving the yield and quality of seawater shrimps, belonging to the field of mariculture water treatment.
Soluble inorganic nitrogen (ammonia nitrogen, nitrite, etc.) and pathogenic microorganisms are major water quality factors that hinder the yield and quality of seawater shrimps. In the process of prawn culture, residual feed, prawn excrement, remains of aquatic animals and the like can be converted into ammonia nitrogen under the action of bacteria. 60-70% of nitrogen in the feed is discharged into the water body, and about 40-90% of nitrogen-containing excrement is converted into ammonia nitrogen. Research shows that the nonionic ammonia in the water body can produce toxic action on hepatopancreas of the prawns, and can obviously reduce the survival rate and the growth performance of the prawns. In addition, intermediate product nitrite can be generated in the nitrification process of ammonia nitrogen, and when the nitrite is more than 1mg/L, the growth rate of aquatic animals can be obviously reduced, and a large amount of farmed organisms can die in serious cases. And ammonia and nitrite can act synergistically, and the prawn can generate higher toxicity. In intensive culture, particularly in the later stage of culture, the concentration of nitrite can reach 20mg/L, seawater components are complex and contain elements such as fluorine, bromine, iodine, sulfur and the like, byproducts in the oxidation process are unavoidable problems, particularly generated chlorine can stay in water for more than 48 hours, the enzyme activity level of shrimps can be influenced by overhigh chlorine concentration in seawater, and the shrimps can die directly due to overhigh chlorine content.
Usually, the seawater culture water treatment adopts frequent water change or drug control of inorganic nitrogen concentration to remove chlorine, which increases the risk of pathogenic bacteria transmission, and once bacteria multiply in quantity, infectious diseases are easy to outbreak. The cost of changing water is big, needs the manual work to operate at the plant constantly, changes water not only to make the marine product reduce production and decrement, and the energy consumption is also big, wastes time and energy, and mariculture direct discharge does not accord with the environmental protection requirement, and the outer row of breeding tail water not only causes harm for the waters, still causes the hindrance to the benign development of aquaculture.
