Circulating water culture system for single-pond culture of penaeus vannamei boone and operation method

Abstract

The invention relates to a circulating water culture system for single-pond culture of penaeus vannamei boone and an operation method, and belongs to the field of aquatic facilities. The circulating water culture system comprises a culture unit and a water treatment unit, and the water treatment unit comprises a particulate matter precipitation removal unit, a biological treatment unit and an ultraviolet disinfection unit. The water treatment unit is arranged under the ground around the culture unit, the upper edge of the water treatment unit is flush with the ground, and grids capable of being taken and placed freely are laid on the water treatment unit. Culture wastewater in the culture unit sequentially enters the particulate matter precipitation removal unit, the biological treatment unit and the ultraviolet disinfection unit after being discharged, and seawater subjected to ultraviolet disinfection is pumped into the culture unit again. According to the invention, a single culturepond is taken as a system unit, water circulation and water treatment are independently carried out, and the problem of cross infection among different culture ponds is avoided; and the water circulation and water treatment system is located under the periphery of the culture pond, so that the culture space is saved, and convenience is provided for operations such as feeding and observation of single-pond culture.

Description

technical field [0001] The invention belongs to the field of aquatic facilities, and in particular relates to a circulating aquaculture system and an operation method for single-pond culture of Penaeus vannamei. Background technique [0002] At present, with the development of aquaculture technology, closed circulation aquaculture has become a sunrise industry of aquaculture. It has the advantages of water saving, land saving, environmental protection, strong controllability, high density, and quality and safety of aquatic products. It is considered to be the 21 It is one of the leading directions for the development of aquaculture industry in the century. However, in the circulating aquaculture system, the density of cultivation is generally high, so a large amount of solid waste is produced, which is the main source of pollution of the aquaculture water body. Timely removal of a large amount of feces and residual bait (cutting from the source) is the key to reducing the or...
