Device and realization method capable of efficiently recycling aquiculture

Abstract

The invention discloses a device and a realization method capable of efficiently recycling aquiculture. The device comprises a plant growing floating bed, a microbial cultivation middle layer and a bottom layer sounding board, wherein the plant growing floating bed is arranged on a water surface and can absorb excrement of fishes, nitrogen and phosphorus in water; the microbial cultivation middle layer is arranged in water below the plant growing floating bed and can purify sewage; and the bottom layer sounding board is arranged below the microbial cultivation middle layer, is matched with the microbial cultivation middle layer and effectively degrades various contaminants in the sewage. The device and the realization method capable of efficiently recycling the aquiculture have good water purifying effect and low cost in the aquiculture, well take advantages of a large amount of harmful substances, ammonia and hydrogen sulfide generated in the water, improve the digestibility of aquatic products, reduce diseases and death rate, and improve the growth rate and meat quality of the aquatic products.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a device and a realization method capable of efficiently recycling aquaculture. Background technique [0002] The current water treatment technology faced by the aquaculture industry is far from meeting the requirements of fish growth. Especially since the adoption of biotechnology for breeding, the effect has been minimal. Fish residual bait, excrement, corpses and biological dead bodies , a large amount of harmful substances, ammonia and hydrogen sulfide will be produced at the bottom of the pond. The water depth of general fish ponds is 2 to 2.5 meters deep. Large-scale high-density farming will increase the cost of water purification and treatment. The oxygen aerator used on the water surface alone cannot meet the growth needs of animal life. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to provide a ...
