example 1

[0017] Such as figure 1 , 2 As shown, taking rainbow trout, sturgeon and carp farming as examples, the establishment of a circulating water aquaculture system is described.

[0018] 1. Each structure of the circulating water aquaculture system is a steel-concrete structure, consisting of a regulating pond 1, a rainbow trout pond 2, a sturgeon pond 3, a carp pond 4, a biochemical pond 5 and a sedimentation pond 6.

[0019] 2. Regulating pool 1 is a rectangular pool with a length of 6000mm, a width of 4000mm, and a height of 5000mm. The proportion of water is 80%, 20% is new water, and new water is the river lake water that meets the surface water environmental quality standard (GB3838-2002) III standard, and new water is injected into adjustment tank 1 by new water pipe 20, and circulating water passes through circulating water The return pipe 15 flows back from the sedimentation tank 6 to the regulating tank 1. The purpose of setting the regulating tank 1 is to mix the circu...

Abstract

The invention discloses a circulating running water aquaculture system which is an integrated system for stepped utilization and purification of aquaculture water in the technical field of the aquaculture water recycling. The system mainly comprises four units including a regulation pond 1, stepped fishponds, a biochemical pond 5 and a settling pond 6. In the system, a stepped culture and filter feeding organism filtering technology is utilized. Inflow water is river and lake water which satisfies the class III standard of the surface water environment quality standard (GB3838-2002); the quality of the recycled water satisfies the class III standard of the surface water environment quality standard (GB3838-2002); and the discharged water satisfies the first class standard A of the discharge standard of pollutants for municipal wastewater treatment plant (GB18918-2002) and can be used for afforesting, farmland irrigating or direct discharging. When the system is used for the aquaculture, the water repeated utilization factor can be improved, the pollutant discharge amount is reduced, and the system has higher economic value and social value.

Description

technical field [0001] The invention relates to a circulating water aquaculture system. The system utilizes a stepped breeding mode and a filter-feeding biological filtration technology to reuse and purify the aquaculture water, and belongs to the technical field of aquaculture water recycling. Background technique [0002] With the continuous development of the aquaculture industry, the negative impact of the traditional flowing water aquaculture model on the environment has gradually increased, and it has also seriously restricted the development of the aquaculture industry. Recirculating aquaculture developed earlier in foreign countries. Developed countries such as the United States, Japan, France, Denmark, and Germany began to conduct industrial fish farming technology research in the 1960s, and recirculating aquaculture equipment has been produced by professional manufacturers. In the 1990s, developed countries introduced world-leading high-tech achievements such as bi...
