Abstract

The invention discloses a water circulating aquaculture system which comprises an aquaculture pond, a rotary disc type filter, a water collecting pond, a water pump, an integrated bio-filter, an ultraviolet disinfector and an aerator. The rotary disc type filter, the water collecting pond, the water pump, the integrated bio-filter and the ultraviolet disinfector are sequentially communicated with a water outlet of the aquaculture pond via flow channels, a water outlet of the ultraviolet disinfector is communicated with a water inlet of the aquaculture pond via a flow channel, the internal liquid level of the ultraviolet disinfector is higher than the internal liquid level of the aquaculture pond, the internal liquid level of the integrated bio-filter is higher than the internal liquid level of the ultraviolet disinfector, the internal liquid level of the aquaculture pond is higher than the internal liquid level of the rotary disc type filter, the internal liquid level of the rotary disc type filter is higher than the internal liquid level of the water collecting pond, the integrated bio-filter comprises an immersed bio-filter, at least one rain falling bio-filter and pipelines, and the immersed bio-filter and the rain falling bio-filters are communicated with one another via the pipelines. The water circulating aquaculture system has the advantage that excellent treatment effects for reducing ammonia nitrogen and nitrite in water can be realized by the water circulating aquaculture system.

Description

technical field [0001] The invention relates to the technical field of circulating aquaculture, in particular to a circulating aquaculture system. Background technique [0002] Water is the living environment of aquatic animals, and water quality plays an important role in aquaculture. The indicators that affect water quality mainly include: dissolved oxygen, ammonia nitrogen, nitrite, and fine particles. The existing circulating water treatment system for aquaculture ponds includes filter ponds, biological purification ponds and ultraviolet sterilizers arranged outside the aquaculture ponds. These treatment ponds are relatively independent and connected in sequence through pipelines. The water in the breeding pond passes through the filter pond, the biological purification pond, and the ultraviolet sterilizer in turn, and the water sterilized in the ultraviolet sterilizer returns to the breeding pond through the pipeline. For example, the Chinese invention patent specific...
