Circulating water treatment system for adult fish industrial aquaculture

Abstract

The invention provides a circulating water treatment system for adult fish industrial aquaculture. The circulating water treatment system comprises a culture pond, a mechanical filtering pond, a sedimentation pond, a protein separation pond, a brush pond, a fluidized bed filler pond, an ozone pond and an ultraviolet disinfection pond which are sequentially connected to form a circulating water purification loop, culture wastewater in the culture pond is sequentially introduced into the mechanical filtering pond, the sedimentation pond and the protein separation pond to be physically filtered, then sequentially passes through the brush pond and the fluidized bed filler pond to be biologically purified and finally passes through the ozone pond and the ultraviolet disinfection pond to be sterilized and disinfected, the treated culture water flows back to the culture pond, a complete culture circulating water treatment loop is formed, the water resource utilization efficiency is improved, and the culture cost of industrial culture is reduced; and the culture environment conditions can be effectively controlled, the annual adult fish culture of the Qinghai Lake is realized, and an important role is played in the rapid recovery of the Gymnocypris przewalskii resource.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a circulating water treatment system for industrial fish farming. 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 and breeding of Qinghai Lake naked carp resources in the past 20 years, especially in recent years by establishing a factory-like circulating aquaculture system to develop Qinghai Lake naked carp Breeding work has made great progress. [0003] The industrial recirculating aquacu...
