Abstract

The invention provides an aquaculture symbiosis system for circulating treatment of aquaculture wastewater, including an aquaculture system and a wastewater treatment system; the aquaculture system includes at least one culture vessel, and the culture vessel includes a culture tank, a filter cloth and a vertical drainage pipe The waste water circulation treatment system includes a water distribution device, a water treatment device, a water supply device and a clear water tank. The water treatment device includes a number of ring-shaped water treatment units that spread outward step by step and are arranged concentrically; the aquaculture wastewater produced after aquaculture passes through a vertical The drainage pipe discharges the aquaculture tank, and the aquaculture wastewater flows out from the upper end of the vertical water inlet pipe under the action of the pipeline pump. The water distribution hole of the water distribution channel is set above the water treatment unit, which can effectively realize the falling water reoxygenation. Several annular water treatment units diffused outwards and arranged concentrically can effectively lengthen the residence time of water in the water treatment units and improve the purification efficiency of pollutants.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aquaculture symbiosis system for circulating treatment of aquaculture wastewater. Background technique [0002] For aquaculture, it is essentially raising water. At present, biological filters are mainly used for nitrification treatment of ammonia nitrogen in aquaculture wastewater. Although this treatment method can make the water body after nitrification treatment meet the normal survival of fish, due to the existence of dissolved oxygen in the system, the nitrate nitrogen in the system cannot be eliminated. In addition, it accumulates in aquaculture ponds for a long time, and there will be certain aquaculture risks. [0003] As a compound aquaculture system, aquaponics can effectively combine aquaculture and vegetable cultivation, which can solve the above-mentioned drawbacks. In the fish and vegetable symbiosis system, the aquaculture water is transported to the hydr...
