Description

A kind of industrial circulating water aquaculture pond

technical field

The utility model belongs to the technical field of aquaculture ponds, in particular to a factory-like circulating water aquaculture pond.

Background technique

The density of industrial fish farming is relatively high, and the amount of solid particles produced is large, including uneaten feed and excrement. The particle size distribution range is wide, and most of the particles have a particle size of 0.1-1.0mm and a density of 1.06-1.19g. /cm ³ , is the main source of water pollution for aquaculture. In the water circulation culture system, they must be removed in time first, so as to reduce the load on the subsequent process links and prevent clogging.

However, the size of the solid particles is inconsistent, so that the solid particles in the culture pond cannot be effectively concentrated at the bottom of the pond and discharged at the sewage outlet. In addition, in the prior art, aquaculture wastewater is seldom recycled, resulting in waste of water resources.

The aeration pipe described above is connected to the blower.

The above-mentioned industrial circulating water aquaculture pond has a simple structure and a reasonable design. The aquaculture pond adopts a double-channel sewage pipe, which can greatly increase the speed of discharging sewage from the bottom, and can effectively discharge solid particles of different sizes, which is a good solution. To solve the problem of solid particle deposition in the culture pond, the culture wastewater can be purified by combining the culture pond, sedimentation pond, algae purification pond, plant planting bed, filter pond and disinfection aeration pond, making it recyclable and saving water resources , but also promote the healthy development of the aquaculture industry.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings.

As shown in the figure, a factory-style circulating water aquaculture pond has a culture pond 1 , a sedimentation pond 9 , an algae purification pond 10 , a plant planting bed 11 , a filter pond 12 and a disinfection and oxygenation pond 13 connected in circulation by pipelines. Among the above-mentioned culture pond 1, sedimentation pond 9, algae purification pond 10, plant planting bed 11, filter pond 12 and disinfection aeration pond 13, the water body flow circulation is promoted by the water pump provided.

The culture pond 1 is a pond made of concrete, and the bottom of the culture pond 1 is a conical structure. The bottom of the culture pond 1 is connected to a sedimentation solid flow pipeline 8 , and the sedimentation solid flow pipeline 8 is connected to a sedimentation tank 9 . The bottom of the culture pond 1 (specifically, the middle position of the bottom) fixes the cylindrical filter 3 through the fixed frame 2 provided, and the cylindrical filter 3 is provided with a filter hole 301, and the lower end of the cylindrical filter 3 is connected to the suspended solid flow pipeline 7, and the suspended The solids flow conduit 7 is connected to a sedimentation tank 9 .
