Aquaculture pipeline circulation system

Abstract

The invention provides an aquaculture pipeline circulation system. The aquaculture pipeline circulation system includes a culture pond, a water inlet pump, a first-level cloth bag filter and a biological purification device. The first-level cloth bag filter conducts physical filtering and interception on solid pollutants in sewage. The biological purification device is communicated with the first-level cloth bag filter. The biological purification device contains nitrobacteria and anti-nitrobacteria and purifies the sewage filtered by the first-level cloth bag filter to decompose nitrogenous organic compounds. The aquaculture pipeline circulation system can achieve circulation and recycling of the sewage in the culture pond, reduce the water consumption, ensure safety and stability of water in the culture pond and the health of aquatic products and guarantee the success of aquaculture.

Description

technical field [0001] The invention relates to the field of box aquaculture, in particular to an aquaculture pipeline circulation system. Background technique [0002] Traditional aquaculture models mainly include soil pond culture, high-level pond culture, industrialized culture and ordinary box culture. In recent years, driven by economic interests, the aquaculture industry has gradually developed from extensive to highly intensive and high-density farming. Capacity and high-load farming, there are some unreasonable feed and excessive use of drugs in the production process, resulting in a large amount of excrement, debris and residual bait and other pollutants, which greatly exceeds the environmental capacity and the self-purification capacity of the breeding water body. In order to reduce the impact of pollution, it can only be replaced with a large amount of fresh water, which not only consumes a large amount of water resources, but also produces a large amount of sewa...

Problems solved by technology

In recent years, driven by economic interests, the aquaculture industry has gradually developed from extensive to highly intensive and high-density farming. Capacity, high-load farming, there are some unreasonable feeding and excessive use of drugs in the production process, resulting in a large amount of excrement, debris and residual bait and other pollutants, which greatly exceeds the environmental capacity and the self-purification capacity of the breeding water body

In order to reduce the impact of pollution, it can only be replaced with a large amount of fresh water, which not only consumes a large amount of water resources, but also produces a large amount of sewage. If it is not treated properly, it will seriously affect the environment

[0003] Moreover, when these pollutants are decomposed in the water body, they need to consume a large amount of dissolved oxygen, resulting in the lack of oxygen in the water body and making the water rich in nutrients such as nitrogen and phosphorus. The ammonia nitrogen and nitrite produced in it will cause certain poisonous damage to aquatic products. It not only pollutes the aquaculture environment itself, deteriorates the quality of aquaculture water, and threatens the survival of aquatic products, but also easily causes eutrophication and damages the ecological environment of fisheries when the aquaculture wastewater is discharged into other water bodies. Microorganisms, in addition to affecting the quality and safety of farmed aquatic products
