Embodiment Construction

[0016] There are 227 fish ponds indoors, with a total area of ​​1590m 2 , total volume 1000m 3 , Breeding Sturgeon commercial fish and fish species. There are 3 drift ditches from the indoor to the outdoor, and 1 sedimentation tank in the open air, with a total area of ​​15m 2 , total volume 20m 3 . In the outdoor greenhouse: there are 12 reverse filter aeration tanks with a total area of ​​72m 2 , total volume 108m 3 , reverse filter aeration tank (see figure 2 ) on the hollowed-out shelf 5, lay suction filter material 3, be biochemical sponge 2 on the suction filter material, be provided with aeration pipe 4 oxygenation on the pond, the dirt of precipitation also can be discharged from valve 6. Constructed wetland area of ​​900m 2 (36m×25m), its depth is 0.3m, the surrounding walls and bottom of the artificial wetland are impermeable layers 8, and the inside is a sand and pebble layer 9. The ornamental aquatic plants 10 selected and planted include: big willow, middl...

Abstract

An ecological fish-culturing system by use of the water drained from factory features that the reverse filter is used for the deposition pool to remove solid substance, the natural ore is used as the adsorbing, filtering and bio-membrane-attaching material, the novel artificial nunja and the appreciative plant growing in said nunja are used to degrade NH4, Cl and nitrate, the microbes are inoculated for biochemical reaction, and the resultant water is aerated for enriching oxygen gas.

Description

Technical field: [0001] The invention relates to the technical field of aquaculture, belongs to the category of industrialized fish farming, and is precisely and specifically an ecological industrialized fish farming system. Background technique: [0002] Industrialized circulating water fish farming is a booming business both at home and abroad. It is land-saving, water-saving, non-polluting, and the breeding production is not affected by the environment, weather and region. It can also artificially control, improve and protect the breeding environment, and improve the yield and quality of farmed fish. Today, with the continuous improvement of living standards, people are eager for more such pollution-free fish products to appear on the market, so the prospect of developing industrialized fish farming is very broad. At present, domestic and foreign industrial circulating water fish farming mainly rely on the use of industrial special equipment to treat the aquaculture disc...
