Culture system and culture method for culturing aquatic product by using circulating water

Abstract

The invention relates to a culture system and a culture method for culturing an aquatic product by using circulating water. The culture system for culturing the aquatic product by using the circulating water comprises a breeding tank and a circulating water treatment system communicated with the breeding tank, wherein the circulating water treatment system comprises a sedimentation tank communicated with the breeding tank, a dirt accumulation tank communicated with the sedimentation tank, an ecological refined filtration tank communicated with the sedimentation tank, a multi-functional foam separation pump communicated with the ecological refined filtration tank, a biological turn plate communicated with the multi-functional foam separation pump, and an artificial wetland pool of which one end is communicated with the biological turn plate and the other end is communicated with the breeding tank. The culture method for culturing the aquatic product by using the circulating water comprises a step of breeding the aquatic product in the breeding tank and a step of treating the circulating water. The culture system and the culture method for culturing the aquatic product by using the circulating water have the advantages that the culture system is simple in structure, and the culture system and the culture method are low in cost, applicable to miniaturization and capable of removing harmful organics and balancing the pH value.

Description

technical field [0001] The invention relates to the field of aquatic product cultivation, in particular to a cultivation system and a cultivation method of aquatic products by recirculating aquaculture. Background technique [0002] At present, recirculating aquaculture is a good way to solve the pollution of aquaculture wastewater and reduce land competition with agriculture and forestry. However, problems such as large and complex equipment, high investment, high operating costs, high technical requirements, and low economic efficiency have resulted in recirculating aquaculture not being widely used in China. Good development, especially the miniaturized complete set of equipment that adapts to our national conditions has not yet been formed. During the process of circulating aquaculture aquatic products, a large amount of harmful organic and inorganic substances will be produced, and the acid-base imbalance of the water body will be caused, which will affect the water qual...

[0002] At present, recirculating aquaculture is a good way to solve the pollution of aquaculture wastewater and reduce land competition with agriculture and forestry. However, problems such as large and complex equipment, high investment, high operating costs, high technical requirements, and low economic efficiency have resulted in recirculating aquaculture not being widely used in China. Good development, especially the miniaturized complete set of equipment that adapts to our national conditions has not yet been formed. During the process of circulating aquaculture aquatic products, a large amount of harmful organic and inorganic substances will be produced, and the acid-base imbalance of the water body will be caused, which will affect the water quality and is not conducive to aquatic products. farming
