Process method and special device for circulating water treatment of crowfish

Abstract

The invention discloses a process method and a special device for treating the circulating water of crowfish, which belong to the field of water treatment. The device includes: a culture pond, a biological pond is arranged around the outside of the culture pond, and a sterilizing component, including a The first substrate placed horizontally on the upper part of the culture pond, the first pump body is arranged on the upper part of the first substrate, the water inlet port of the first pump body communicates with the biological pond through the pipe body, and the surface of the first substrate adjacent to the end of the culture pond is provided with a half-way The diversion semi-through groove, the inner wall of the culture pool below the first base plate is connected with the first rotating shaft with the axis horizontally arranged, the first rotating shaft is equipped with a rotating shaft sleeve, and the bottom surface of the rotating shaft sleeve is provided with a horizontally arranged flow blocking baffle to prevent flow Both sides of the baffle are connected with the rotating shaft sleeve through the first mesh plate. The device of the invention has strong applicability, good versatility, energy saving and high efficiency, effectively improves the filtration efficiency and effect of physical purification, shortens the cycle period, and ensures the quality of purified water and the growth environment conditions of cultured products.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a process method and a special device for circulating water treatment of totoaba fish. Background technique [0002] The family Sciaenidae belongs to the order Perciformes, and there are more than 300 species in 70 genera in the world, which is one of the families with the most genera and species in Perciformes. There are many species and genera of cichlids in my country's coastal areas, including 17 genera and more than 30 species. The vast majority of species of Totoaba family have delicious meat and high economic value, and are important targets for marine fisheries and mariculture. Sclerotinidae is one of the most productive groups of marine economic fish in my country, and it is an important marine economic fish in China. However, in the process of fish farming, the breeding water needs to be changed regularly to ensure the water quality is clean, which is suitab...

Problems solved by technology

However, in the process of fish farming, the breeding water needs to be changed regularly to ensure the water quality is clean, which is suitable for farming. This way of changing the water consumes a lot of water and pollutes the water environment. The water circulation treatment process purifies the breeding sewage. After purification The water body will continue to be used for breeding, which has the characteristics of not being restricted by the external environment, saving water, saving land, high-density intensification, controllable production, and zero discharge of pollutants. It is an inevitable trend in the transformation of aquaculture methods. In the process, when the water purification effect is poor, the circulating water body is not suitable for aquaculture, and it also relatively causes the phenomenon of low quality of cultured products
