Embodiment Construction

[0023] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0024] Such as figure 1 , A circulating water ecological breeding system of the present invention includes a breeding pond, a layered water injection system, a sewage collection pond, a sewage filter pond, a sewage collection pond, and an ecological purification pond. The layered water injection system introduces water from above and below the water surface of the culture pond, pushes the culture residue to the back end of the culture pond, and then passes through the sewage collection pond, the sewage filter pond, and the ecological purification pond to filter and purify in sequence. Afterwards, the circulating water is injected into the culture pond through the layered water injection system.

Abstract

The invention provides a circulating water ecological-breeding system and belongs to the technical field of high-density aquatic product breeding. The circulating water ecological-breeding system comprises a breeding pond, a layered water injection system, a sewage filtering pond, a dirt collecting pond and an ecological purification pond. The layered water injection system guides water from the position above the water surface of the breeding pond and the underwater position, breeding residues are pushed towards the rear end of the breeding pond and then are sequentially subjected to filtration and purification of the dirt collecting pond, the sewage filtering pond and the ecological purification pond, and purified water is injected into the breeding pond through the layered water injection system. The circulating water ecological-breeding system forms flowing circulating water breeding and simulates river flowing water breeding, and the problems of slight high content of hazardous substances such as nitrous acid and ammonia nitrogen due to accumulation of too much fish excrement and feed residues of fish at the bottom of the breeding pond are solved.

Description

technical field [0001] The invention relates to the technical field of high-density aquatic product cultivation, in particular to a circulating water ecological cultivation system. Background technique [0002] The traditional extensive farming model is a production method that depends on the weather, which is inevitably affected and restricted by natural conditions such as climate and water quality changes. It not only has problems such as low yield, monotonous breeding varieties, frequent disease occurrence, and high breeding risks. , and cause serious environmental damage and pollution, which is not conducive to the effective use of resources and the sustainable development of aquaculture. The abuse of antibiotics and other drugs has led to a decline in the quality of aquatic products, and the food safety of farmed aquatic products cannot be guaranteed, which has largely affected the sustainable development of aquaculture. [0003] The sewage discharge of aquaculture pon...
