Circulating water treatment system for industrial aquaculture of fingerlings

Abstract

The invention provides a circulating water treatment system for industrial aquaculture of fingerlings. The circulating water treatment system comprises an aquaculture pond, a mechanical filter pond, a sedimentation pond, a primary brush pond, a fluidized bed filler pond, a secondary brush pond, a coral pond, an ultraviolet disinfection pond and a water storage pond which are sequentially connected to form a circulating water purification loop, aquaculture wastewater in the aquaculture pond is sequentially introduced into the mechanical filter tank and the sedimentation tank for physical filtration, then sequentially passes through the primary brush tank, the fluidized bed filler tank, the secondary brush tank and the coral tank for biological purification and finally passes through the ultraviolet disinfection tank and the water storage tank for comprehensive treatment, the treated aquaculture water flows back to the aquaculture pond, and a complete aquaculture circulating water treatment loop is formed. According to the circulating water treatment system for industrial aquaculture of the fingerlings, the utilization efficiency of water resources is improved, the aquaculture cost of industrial aquaculture is reduced, the aquaculture environment condition can be effectively controlled, the yearly fingerling aquaculture of the Qinghai lake is realized, and the qinghai-lake naked carp fingerlings artificially cultured every year are released into the Qinghai lake as required.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a circulating water treatment system for fish species industrialized cultivation. Background technique [0002] The naked carp in Qinghai Lake belongs to Cyprinidae, Cyprinidae, Schizothorax subfamily, and Naked carp, commonly known as Huang carp. It is the only economic fish in Qinghai Lake and occupies a very important position in the ecosystem of Qinghai Lake. Due to its historical and natural reasons, the naked carp resources in Qinghai Lake were once greatly damaged. In order to speed up the recovery of its resources in Qinghai Lake, the Qinghai Lake Naked Carp Rescue Center has carried out artificial breeding of Qinghai Lake naked carp resources in the past 20 years, especially in recent years through the establishment of a factory breeding system to carry out the breeding of Qinghai Lake naked carp The work has made great progress. [0003] The industrial circulating...
