A factory-like circulating water high-density three-dimensional ecological breeding system

Abstract

The invention provides a factorized circulating water high-density three-dimensional ecological breeding system which comprises a plurality of breeding tanks, a breeding circulating water treating system communicated with the breeding tanks, and three-dimensional spraying aquaculture columns arranged on the upper portions of the breeding tanks. The factorized circulating water high-density three-dimensional ecological breeding system is characterized in that the breeding circulating water treating system comprises a water collection tank, a water pump, a microfilter, a decarburization area, a nitration area, a degassing area, an ultraviolet sterilizing area and a temperature adjusting and tempering tank sequentially along a water flow direction, the water collection tank is communicated with the breeding tanks through sewage inlets, and the temperature adjusting and tempering tank is communicated with the three-dimensional spraying aquaculture columns through a clean water outlet and the water pump; a biological filtering area or a low-speed nitration area are arranged between the nitration area and the degassing area; a mud blocking slot is formed between the decarburization area and the nitration area, a plurality of mud-blocking water-passing holes are formed in a wall of the decarburization area on one side of the mud blocking slot, a plurality of nitration water incoming holes are formed in a wall of the nitration area on the other side of the mud blocking slot, and bottom height of the mud-blocking water-passing holes is greater than height of a mud discharging pipe in the decarburization area. The factorized circulating water high-density three-dimensional ecological breeding system is low in investment, high in space utilization rate, healthy and efficient.

Description

technical field [0001] The invention relates to the technical field of aquaculture and soilless cultivation, in particular to a high-density three-dimensional ecological cultivation system of industrial circulating water. Background technique [0002] With the rapid development of economy and society, the increasing industrial and agricultural pollution and domestic wastewater discharge have led to the continuous deterioration of the ecological environment of water areas, which has seriously affected aquaculture production. At the same time, because humans are at the top of the food chain, aquatic products raised after water pollution Ultimately, it seriously endangers human health and affects the quality of the population. With the development of technology, the industrial recirculating aquaculture system, which is energy-saving and environmentally friendly, and also plays an important role in preventing the occurrence of breeding diseases and improving product quality, has...

Problems solved by technology

However, this small device cannot meet the needs of industrialized farming, and cannot increase the breeding density per unit volume of aquaculture water. Moreover, increasing the nutrient solution in the water body will reduce the quality of the aquaculture water, which is not conducive to the growth of fish.

The above technical solutions cannot effectively increase the breeding density per unit volume of aquaculture water, the space utilization rate is low, and the investment cost is large, which makes the cost per unit output high, and it is difficult to meet the needs of the market.
