Water circulating ecological system for aquaculture

Abstract

The invention relates to a water circulating ecological system for aquaculture. The water circulating ecological system comprises an aquaculture main body ecological breeding tank, a biological purifying tank, a water purifying tank and a residue treatment ecological breeding tank. Environmental engineering for ecological breeding is constructed by the water circulating ecological system, and the breeding environment is controlled and optimized, so that aquaculture breeding dirt is cleared up by virtue of ecological mating of microorganism, plants and animals, and therefore, water self-cleaning effect of an ecological environment is achieved. By virtue of a recycling economy mode, the water is self-cleaned and utilized in a multi-stage manner to form an industrial chain of a plurality of products, so that duplex economic value added effect is produced. The production system ecologically controls the aquaculture, so that breeding water can be saved for over 70%, and water quality is regulated and optimized, and therefore, healthy aquaculture is implemented.

Description

technical field

[0001] The invention belongs to the technical field of agricultural aquaculture, and in particular relates to an aquaculture water cycle ecosystem. Background technique

[0002] In recent years, the rise of artificial aquaculture, especially high-density, high-yield large-scale farming, not only pollutes the environment, but also brings hidden dangers to food safety. During the aquaculture process, most of the surplus protein in the feed will be excreted in the water in the form of ammonia nitrogen and nitrite. Under rainfall, high temperature and other environments, fish and shrimp are prone to diseases, and the use of antibiotics is increased accordingly, and drug residues increase the risk of food safety. The excrement and feed residues of aquatic animals are deposited in the water, fermented and tasteless, accumulating over time, resulting in eutrophication of the water body, making it difficult for fish and shrimp to survive, and sewage discharge will b...

Examples

Embodiment Construction

[0026] The following examples illustrate the present invention in further detail, but the present invention is not limited to such examples.

[0027]As shown in the accompanying drawings, a production system for healthy aquaculture, sewage ecological treatment and water purification recycling includes an ecological breeding pond for aquatic products, a biological purification pond, a primary water purification pond, a secondary water purification pond, reclaimed water Reuse pool, residue treatment ecological breeding ground and other structural components. Carry out engineering construction according to the structure of the production system. The aquatic main ecological breeding pool 1 is equipped with an aerator, a microporous aeration pipeline, a bottom residue flushing pipe, a suspended micro-ecological preparation water purifier, and a floating row for planting aquatic plants, and is connected to a biological purification pool through a waste water residue discharge pipeli...
