Abstract

The invention discloses an ecological-type closed-water-recycling aquaculture system and belongs to the technical field of aquaculture. A specific technical scheme comprises the steps: constructing a factory building for the culture system, wherein the factory building comprises a water distribution area, an aquaculture area, a water storage tank, a microalgae culture area and a microalgae collecting area; and injecting water to the water distribution area, subjecting the water to ecological purification sequentially by the aquaculture area, a filtering basin, the microalgae culture area and the microalgae collecting area, and then, enabling the purified water to return to the water distribution area, wherein the aquaculture area is used for carrying out production operation on aquatic-product commercial crops, the filtering basin is used for filtering impurities of the aquaculture area, the microalgae culture area is used for culturing microalgae, and the microalgae collecting area is used for carrying out flocculated collecting on the microalgae. According to the culture system, progressive coupling is carried out in accordance with functional areas of different trophic levels, so that the economic benefit of aquaculture is greatly improved; and culture water is approximate to zero draining, so that surrounding farmland and sea areas are not polluted, and the aims of high efficiency and health are achieved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an ecological closed water circulation aquaculture system. Background technique [0002] At present, aquaculture is facing two major problems, one is water resources and environmental pollution caused by aquaculture, and the other is the problem of aquatic product diseases. These two problems are closely combined, and pollution of the water environment will cause harmful The growth of bacteria causes frequent occurrence of diseases; environmental pollution and drug abuse caused by frequent occurrence of diseases have drawn much attention to the safety of aquatic products. Drug residues are so serious that malachite green residues are detected in mandarin fish exported to Hong Kong. This problem has been reflected in eels exported to Japan from pesticides exceeding the standard to prawns exported to the EU with chloramphenicol exceeding the standard. Confidence has declined a...
