Problems solved by technology

Then relying on physical and chemical effects to maintain water quality not only cannot guarantee the natural water environment, but also is costly. Therefore, how to develop a natural-based aquaculture water quality solution and realize low-cost in-situ ecological purification of aquaculture water is the key to the healthy development of modern aquaculture. The essential

Embodiment 1

[0031] like Figures 1 to 4 As shown, the present embodiment provides a water body self-circulating freshwater ecological breeding system, including a breeding area 1 and an ecological purification area 2; the ecological purification area 2 is provided with a water inlet well 3 and a drainage well 4, and the water inlet well 3 is used for the breeding area. The water in 1 is discharged into the ecological purification zone 2, and the drainage well 4 is used to discharge the water in the ecological purification zone 2 into the aquaculture zone 1.

[0032] In this specific embodiment, the breeding area 1 is square; the breeding area 1 and the ecological purification area 2 are concentric structures, and the ecological purification area 2 is located around the breeding area 1 . The ratio of the volume of the ecological purification zone 2 to the water capacity of the aquaculture zone 1 is 1:7. The outer wall of the ecological purification zone 2 is 20-40cm higher than the inner ...

Embodiment 2

[0046] like Figures 1 to 4 As shown, in the present embodiment, the breeding area 1 is a square structure, the water depth is 2m, the length is 15m, the width is 10m, and the water surface area is 150m 2 , under the design water level of breeding area 1, the water capacity is 300m 3 , the ratio of the construction volume of the ecological purification area 2 to the design water capacity of the breeding area 1 is 1:5, and the effective volume of the purification area is 60m 3 .

[0047] The ecological purification area 2 is located on the periphery of the breeding area 1. It is a ring structure with a width of 1m, a filling height of 1.1m, and a total effective volume of 50m. 3 The outer enclosure wall 17 of the purification area is higher than the inner enclosure wall 1620cm of the purification area.

[0048] The layered filling of granular fillers 11 in the ecological purification zone 2 is as follows from top to bottom: the first layer of coarse-grained fillers 111 has a...

Abstract

The invention discloses a water body self-circulation fresh water ecological aquaculture system, which relates to the technical field of fresh water aquaculture and comprises an aquaculture area and an ecological purification area, a water inlet well and a water drainage well are arranged in the ecological purification area, the water inlet well is used for draining water in the breeding area into the ecological purification area, and the water drainage well is used for draining water in the ecological purification area into the breeding area. According to the water body self-circulation fresh water ecological aquaculture system, pollutants generated in the fresh water aquaculture process are removed through the combined effect of plants, filler and microorganisms, in-situ purification of the water body is achieved, the cost is greatly reduced, and the water quality guarantee problem in the fresh water aquaculture process is solved.

Description

technical field [0001] The invention relates to the technical field of freshwater aquaculture, in particular to a water body self-circulation freshwater ecological aquaculture system. Background technique [0002] With the improvement of people's living standards in my country, the demand for high-quality aquatic products is increasing. However, due to the strict control of wild aquatic product fishing by ecological protection, the traditional fishing industry has long been unable to meet the demand, and the aquaculture industry has ushered in vigorous development. However, high-quality aquatic products need high-quality water quality as the basis, and water quality problems in aquaculture have attracted more and more attention. [0003] The water quality problems in the aquaculture process are mainly due to the accumulation of fish excreta, excess fish feed residues, fish medicines, etc. Oxygen capacity is reduced, resulting in hypoxia, slow metabolism of fish itself, and...
