Problems solved by technology

The disadvantages are: large number of equipment, large investment in equipment, low land utilization rate, complex pipeline setting, and inconvenient operation and management
[0007] Circular fish ponds or fish ponds with cut corners are generally used in the high-density culture of the existing industrial circulating water, which has the disadvantages of low utilization rate of land area, small effective culture water body, complicated grading fishing operation, and high labor intensity.

Embodiment 1

[0045] In the prior art, the water treatment processes of centralized and decentralized aquaculture are as follows: figure 1 . The decentralized water treatment process is that the water in a single fish pond is extracted and returned to the fish pond after physical filtration, biological filtration, degassing, sterilization and oxygenation in sequence.

[0046] The centralized water treatment process is: the water in multiple fish ponds (fish ponds I, II, II) is pumped out and collected together, and then returned to each fish pond after physical filtration, biological filtration, degassing, sterilization and oxygenation treatment.

[0047] The internal circulation fish pond of the present invention is:

[0048] like image 3 Shown, the structure of the inner circulation fish pond (fish pond 1) comprises the central fish pond 15, and the shape of the central fish pond is an octagon with four cut corners, and its adjacent sides are respectively the outer wall long side a, th...

Embodiment 2

[0067] like Image 6 As shown, the center fish pond is circular, and the rectangle cut out from the center fish pond has four corners. A precipitation system is set on one of the corners, and the structure and working principle of the precipitation system are the same as those in Example 1.

[0068] An inner circulation system is arranged on the remaining three corners, and the structure and working principle of the inner circulation system are the same as those of the first embodiment.

Abstract

The invention relates to the technical field of aquaculture, and discloses an internal circulation fishpond and a circulating water treatment process. According to the internal circulation fishpond and the circulating water treatment process, an air striping device, a physical filtration device and a biological filtration device are arranged in vacant regions, such as corners of the fishponds; multiple functions, such as plug flow, oxygenation, degassing, solid filtration and biological filtration, are integrated in the design of the fishpond; through arranging an air stripping pump, a moving bed biofilter and a vertical flow precipitator and the like, the water treatment function of the fishpond is perfected and enhanced, and the fishpond has the functions of oxygenation, degassing, physical filtration and biological filtration; the circulating speed of a water body is reduced while the solid utilization rate is improved; through reducing the treatment load amount of a water treatment system, the circulating speed of the water body and the operating energy consumption of a circulating water pump are reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an internal circulating fish pond and a process for treating circulating water of the fish pond. Background technique [0002] Flowing water fish ponds are commonly round, oval, rectangular, square with cut corners, octagon, etc. Different fish pond shapes have their own advantages and disadvantages. Circular pools have higher construction cost, good water exchange and pollution discharge effects, and high production per unit of water, but are inconvenient to operate and have low land utilization; Sewage discharge is not ideal; rectangular chamfered and octagonal pools are less costly, have good water exchange and sewage discharge, and are easy to operate, but have low land utilization. [0003] Fish ponds are used as habitats for fish farming. In industrial closed recirculating aquaculture, their functions are not limited to this. They also have the functions of collecting ...
