Embodiment 1

[0024] The present invention designs swimming fish breeding density to be 50kg / m 3 , the total area of ​​the two-span workshop is 2000m 2 , the average water depth of the workshop is 1.35 meters, each workshop has 16 cement pools with a volume of 32 cubic meters, and the total water body of the site is 1024 cubic meters. The number of daily exchanges is 5 times, and the total amount of recovered water per hour is 200m 3 , The recovery rate of circulating water is 95%. The site is a two-span workshop, each workshop is designed with a relatively independent circulating water treatment system, and the circulating water volume of each water treatment unit is 100m 3 / h, so that the field can carry out breeding and hatching of different water temperatures and species at the same time, saving energy. The water treatment equipment of each workshop is installed on the west of each workshop, and the area of ​​each equipment room is 45m 2 .

Abstract

An intensive circulating water culture system comprises at least one water purification system which is configured in an aquaculture pond and mainly composed of a water pump, a filter and a sterilizing device. The water pump is at least arranged between a return water regulating pond and a sand filter tank, and the sand filter tank is then sequentially connected with a biofilter and a protein skimmer to form the filter; the water purification system is configured with a dissolved oxygen release device, and the device oxygenates the water purification system by connecting with the protein skimmer; and the water purification system is configured with an ozone generator and an automatic temperature regulating unit which are connected with the water purification system respectively by pipelines. The intensive circulating water culture system is characterized by simple structure, small occupied space, low cost, good circulating water treatment effect, meeting requirements for intensive aquaculture and the like.

Description

technical field [0001] The invention relates to a circulating aquaculture system adopting a novel water quality purification system, in particular to an intensive circulating aquaculture system, which belongs to the technical field of aquaculture. Background technique [0002] The development of aquaculture is inseparable from the rapid development of today's society. Traditional aquaculture mainly relies on a large-scale aquaculture pond, which consumes a lot of water and waste water, so it not only consumes a lot of energy, but also has a great impact on the environment. Usually, a large amount of excrement and residual bait produced in the aquaculture process It will accumulate in the aquaculture pond, and then cause the water quality in the aquaculture pond to gradually deteriorate, which will lead to lesions of the cultured plants and reduce the output and quality of aquaculture. [0003] In order to solve the disadvantages of the above-mentioned traditional aquacultur...
