Description
Technical Field
The invention relates to a saline-alkali beach culture water body circulation system, and belongs to the technical field of aquaculture industry.
Background
The tidal flat is a dynamically-changed sea-land transition zone, is a marine region which is developed and utilized by human beings at the earliest, the total area of the marine tidal flat in China is more than 200 hectares, the national tidal flat culture area in 2018 is more than 90 hectares, the fishery yield exceeds 850 million tons, accounts for about 45 percent of the marine culture yield, and plays an important role in marine protein output. In the traditional culture mode, the fed baits and the feces of cultured organisms are directly discharged into a water body, so that the pollution condition of the culture tail water is increasingly severe. Therefore, the treatment mode of the aquaculture tail water and how to recycle the aquaculture tail water are problems which are urgently needed to be solved by the aquaculture industry.
At present, the purification of the culture tail water mainly comprises three types of pond purification, facility purification and wetland purification. Pond purification is one of the main forms of aquaculture tail water treatment, and mainly comprises basic principles of degradation, precipitation, oxidation, adsorption, filtration and the like. However, more suspended matters exist in the water in the filter tank, and workers need to clean the water regularly or replace the filler, so that a large amount of manpower and material resources are needed, and the water is not beneficial to saving and utilizing resources. The basic principles of facility purification and pond purification are similar, but the facility purification is higher in specialty, more detailed in operation technology, higher in required cost and supported by enough economic strength, pigments, proteins, organic debris and the like in water are removed by using the adsorption effect of activated carbon in a common mode, and the water treatment amount is small, the cost is high and the application range is small. Compared with the two purification modes, the wetland purification is a complex multifunctional ecosystem, and impurities in water are removed by utilizing various modes such as decomposition, chemical adsorption, physical filtration and the like of microorganisms, so that the wetland purification has an obvious effect, and particularly has a strong cleaning effect on nitrogen and phosphorus elements in the aquaculture tail water. The wetland purification can be used for planting wetland plants according to the actual pollution condition of the water area, and the purification effect on the water body is achieved by utilizing the functions of the plants through the optimization of the water area engineering design and the process flow. And plant cultivation not only can promote the oxygen supply of the water area, but also can beautify conveniently through artificial design. Part of the aquatic plants can also be used as feed for grass carp and the like, so that the culture cost is effectively reduced. However, it is worth noting that many filtering and purifying systems suitable for fresh water cannot work normally in the purification of the mudflat aquaculture water body due to the high salinity of the mudflat water body; in addition, the wetland area required by wetland purification is large, and simultaneously, because the beach soil has low nutrient content and high salinity, the difficulty of screening and culturing wetland plants in saline-alkali beach areas is large. Therefore, the saline-alkali beach area is lack of a simple and practical cultivation tail water treatment technology
