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

Embodiment 1

[0045] See attached Figure 1-9 Shown, a kind of totoaba fish circulating water treatment special device, comprises:

[0046] Culture pool 10, the outside of culture pool 10 is surrounded by biological pool 20,

[0047] The sterilization assembly 30 includes a first substrate 36 fixed on the top of the culture pond 10 and placed horizontally. The top of the first substrate 36 is provided with a first pump body 31 , and the water inlet port of the first pump body 31 communicates with the biological pool 20 through a tube. The surface of the first base plate 36 adjacent to the culture pond 10 end is provided with a half-pass diversion half-pass groove 35, and the water outlet end of the first pump body 31 sends the water body into the diversion half-pass groove 35 through the pipe body and makes the water flow along the guide The flow half-through groove 35 enters the culture pond 10,

[0048] Wherein, the inner wall of the culture pond 10 below the first base plate 36 is conn...

Embodiment 2

[0066] A kind of process method of circulating water treatment of totoaba fish:

[0067] - Detect the average concentration of ammonia nitrogen and COD in the aquaculture water, and judge whether it exceeds the set parameters;

[0068] - After judging that the detection parameters of the aquaculture water body exceed the set parameters, the aquaculture water body is extracted from the aquaculture pond 10, filtered through the filter assembly 50, and then processed by the air flotation assembly 40 and discharged into the biological pool 20;

[0069] -The water body in the biological pool 20 is sterilized by the sterilizing component 30 and sent into the breeding pool 10;

[0070] -repeating the above steps to control the detection parameters of the aquaculture water body to be within the range of the set parameter values.

[0071] The present invention controls the filter assembly 50 and the air flotation assembly 40 to purify the aquaculture sewage through continuous detectio...

Embodiment 3

[0073] The further optimization scheme of present embodiment on the basis of embodiment 1 is: see appendix Figure 10 , 11 As shown: one end of the filter barrel 70 is provided with a cleaning assembly 80, and the end of the filter barrel 70 provided with the cleaning assembly 80 is provided with a second support link 72 arranged in a staggered manner, and the second support link 72 and the filter barrel 70 The inner wall of the opening at the end is connected and adjacent to the second support link 72 to form a sewage hole body 73, and the middle part of the second support link 72 arranged in a staggered manner passes through the filter shaft 59, and the filter shaft 59 is connected with a first rotating plate body 82, The plane of the first rotating plate body 82 is arranged perpendicular to the axis of the filter rotating shaft 59, one end of the first rotating plate body 82 is assembled with the filtering rotating shaft 59, and the upper part of the other end is hinged to ...

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...
