Aquaculture pond utilizing circulating water engineering

Abstract

The invention belongs to the field of aquaculture, and discloses an aquaculture pond utilizing circulating water engineering. The aquaculture pond comprises a pond, wherein a settling zone is arranged at the right end in the pond, a front filtering zone is arranged at the rear end of the settling zone, a rear filtering zone is arranged at the rear end of the front filtering zone, and a central suction port is formed in the center in the pond. By arranging the front filtering zone, a gas stripping device, the rear filtering zone and other systems, the function of high water dissolving efficiency of oxygen is achieved, the front filtering zone blocks and stores water in the settling zone, at the moment, the gas stripping device located at the bottom starts to conduct aeration from bottom to top, the upper layer, the middle layer and the lower layer of the water body make full contact with air, meanwhile, the water flow enters the rear filtering zone through the generated thrust, the aeration step of the front filtering zone is repeated, so that the water body is rich in oxygen when being discharged, and compared with the prior art, the aquaculture pond has the advantage of being high in aeration efficiency.

Description

technical field [0001] The invention belongs to the field of aquaculture, in particular to an aquaculture pond using circulating water engineering. Background technique [0002] Pond aquaculture occupies an important position in aquaculture in my country. At present, the more common pond engineering circulating aquaculture modes include waterwheel or impeller aerator drive mode. [0003] The driving mode of waterwheel or impeller aerator is based on the existing pond, by putting in waterwheel or impeller aerator to drive the surface water flow with the impeller and trying to stir the water flow while improving water and air exchange and oxygenation. In practical applications, the model cannot effectively drive the water flow at all, but only increases the flow velocity of the water on the surface of the water body, which is ineffective for the flow of the middle and lower water bodies, and the flow has no specific direction, and the efficiency of oxygenation is low.

[0003] The driving mode of waterwheel or impeller aerator is based on the existing pond, by putting in waterwheel or impeller aerator to drive the surface water flow with the impeller and trying to stir the water flow while improving water and air exchange and oxygenation. In practical applications, the model cannot effectively drive the water flow at all, but only increases the flow velocity of the water on the surface of the water body, which is ineffective for the flow of the middle and lower water bodies, and the flow has no specific direction, and the oxygenation efficiency is low

[0004] In addition, the current treatment of wastewater in pond farming is often to directly discharge wastewater with drainage pumps, and then draw new water from other places. Without any wastewater treatment measures, the water body cannot be recycled, wasting water resources and polluting the environment.
