A kind of circulating aquaculture device and method

Abstract

The invention belongs to the technical field of aquaculture, and relates to a circulating aquaculture device and method. The sewage outlet at the bottom of the self-cleaning circulating water aquaculture pool is connected with the ecological biological water purification pool through the sewage pipe, and the water body contained in the ecological biological water purification pool is provided with An artificial floating island planted with aquatic organisms, the bottom of the ecological biological water purification pool is covered with sand, and the underground soil layer under the sand forms a soil layer microbial filter bed. There is an open shaft in the center of the ecological biological water purification pool, and the lower end of the open shaft A porous water filter pipe and a submersible pump are provided, and the submersible pump is connected to the water inlet device, and a Venturi aeration tube is sleeved on the water inlet device; this method is realized through the mutual cooperation of the characteristics of the breeding water body and the characteristics of the microbial flora in the soil layer Water recycling, purification, reuse, its input and operation costs are low, the operation method is simple, the waste discharge is almost zero, the breeding effect is good, the density is high, the environment is friendly, safe and harmless.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of aquaculture, and relates to a circulating aquaculture device and method, which can realize the circulating aquaculture without using facilities such as sedimentation tanks, filtering devices, protein separators and ultraviolet sterilizers. [0003] Background technique: [0004] Aquaculture is a production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. my country's aquaculture industry is relatively developed, and the total output of freshwater aquaculture has been ranking first in the world for many years; but it also faces serious challenges: on the one hand, the overall ecological environment of water areas It is deteriorating. In recent years, catastrophic events caused by environmental pollution in water areas, such as blue-green algae outbreaks, the spread of enteromorpha, and aggravated fish diseases, have occurred frequently, causing great har...

Problems solved by technology

[0005] As we all know, the culprit of the deterioration of water quality in aquaculture ponds is the organic solid deposits at the bottom of the pond, because many residual bait, feces, and the corpses of protozoa and microalgae are deposited on the bottom of the pond during the cultivation process, and they are affected by the action of microorganisms. Many harmful protozoa and bacteria are bred under corruption and deterioration. At the same time, a large amount of harmful gases and substances are dissolved in the water. A large number of water changes or sedimentation and filtration are carried out, but it is difficult to fundamentally solve the problem. Therefore, the present invention designs a device and method for a circulating aquaculture model, which is especially suitable for the development of aquaculture in areas with poor water resources and land shortages. Has good application prospects and economic value
