Circulating water purification aquaculture system

Abstract

The invention discloses a culture system realizing purification of circulating water. A culture area is connected with a stepped pond through a pipeline, and the stepped pond is connected with a purification and temperature adjustment system which is connected with the culture area through a pump and a pipeline. A sedimentation tank and a filtration well are connected in the purification and temperature adjustment system, at least one overflow trough is arranged between the sedimentation tank and the filtration well, the filtration well is connected with a temperature adjustment well, the part, connected with the temperature adjustment well, of the filtration well is a filtration wall, other parts of the filtration well are water resistance walls, the top edge of the temperature adjustment well is higher than that of the filtration well, and the depth of the temperature adjustment well is larger than that of the filtration well. Emerging plants are planted in the sedimentation tank. According to the provided culture system realizing purification of circulating water, the circulating water for culture is purified naturally through combination of the stepped pond wetland, the purification and temperature adjustment system and the culture area, burden to the environment is avoided in a purification process, and the water quality meets the standard of aquatic products with the requirement for high water quality.

Description

technical field [0001] The invention relates to a water purification system, in particular to a circulating water purification breeding system. Background technique [0002] In the prior art, there is a plan to use circulating water for breeding. In the process of water circulation, sedimentation, overflow, and aeration are often used for water purification. The problem is that the purification effect of this purification method is poor. The organic matter in the water still exceeds the standard, resulting in poor disease resistance of the cultured aquatic products. The quality of aquatic products is not high. [0003] For some aquaculture aquatic products with high water quality requirements, such as giant salamanders, in the prior art, it is difficult to adopt the water circulation mode for aquaculture. [0004] Chinese patent document CN102669040A has recorded the scheme of adopting mountain spring water and groundwater circulation, but the output of high-quality mounta...

Problems solved by technology

[0002] In the prior art, there is a plan to use circulating water for breeding. In the process of water circulation, the water purification method of sedimentation, overflow and aeration is mostly used. The problem is that the purification effect of this purification method is poor. The organic matter in the water still exceeds the standard, resulting in poor disease resistance of farmed aquatic products

The quality of aquatic products is not high

[0003] For some aquaculture aquatic products with high water quality requirements, such as giant salamanders, it is difficult to use water circulation for aquaculture in the prior art

[0004] Chinese patent document CN102669040A records the scheme of using mountain spring water and groundwater circulation, but the output of high-quality mountain spring water and groundwater is usually small, which is difficult to meet the requirements of aquaculture production
