Round potted pool recirculating culture system

Abstract

The invention provides a round potted pool recirculating culture system. The system comprises a round potted pool, a sewage disposal well, a rinsing pipe, a sand sediment trap, a sedimentation tank, apurification pond and a water storage tower, wherein the bottom of the round potted pool is communicated with the sewage disposal well; the sewage disposal well is communicated with the sand sedimenttrap through the rinsing pipe; the sand sediment trap is communicated with the sedimentation tank through a pipeline; the sedimentation tank is communicated with the purification pond through a pipeline; water drained from the round potted pool is filtered, sedimented and purified, and is delivered into the water storage tower through a water pump and a the pumping pipe; the water is oxygenatedthrough the water storage tower, and is delivered into the round potted pool through a water delivery pipe to achieve recirculating culture. The round potted pool is a round pool has a round potted-shape; and oxygenation water propellers are respectively arranged on two inner sides of the round potted pool, and are used for propelling water in a clockwise or anticlockwise manner. The round pottedpool recirculating culture system can be used for constructing a set an integral aquaculture, and can achieve the aims of environment-friendly culture, high yield and remarkable economic ecological benefit.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a circular aquaculture system for a pool at the bottom of a round pot. Background technique [0002] As the world population continues to increase, water resources will soon become a limiting factor for many industries, the nutritional cost of food production will further increase, the demand for high-quality aquatic products in Southeast Asian countries will increase significantly, and the fishing industry will maintain the status quo Or a downward trend, farmed aquatic products will occupy the main market. At the same time, the cost of water for agriculture, especially aquaculture, increases and the pressure on the environment increases. The biggest challenge of agricultural production in the 21st century is to use less resources to produce 3 times more products. The World Bank's Global Fisheries Plan-2030 Fisheries Project initially proposed that the world's aquaculture ...

Problems solved by technology

[0004] After research, it is found that there are three main disadvantages of circulating water aquaculture in ponds: first, the daily operating costs are high, and fish farming in ponds mainly relies on high-power water pushing and aeration equipment to continuously operate to provide high-density cultured fish in the tank. To provide sufficient oxygen and create a circular water flow in the pond, the daily power consumption is relatively large, and the operating cost is high; there are many circulating water farming machinery and equipment in the pond, which are easily damaged and replaced by wading, and regular maintenance is required, especially to prevent accidental power outages. It is necessary to complete the emergency power generation system and backup oxygenation equipment, which will undoubtedly increase the manpower and material costs of the operation

The second is that the "runway" tank has poor sewage suction effect. Although a waste sedimentation area such as residual bait and fish feces is set up in the section of the circulating water aquaculture tank in the pond, and equipment is used to extract and absorb sewage, the residual bait and fish feces in the water often flow with the water body. In a suspended state, the equipment can only extract a small amount of dirt in the water, and if it encounters dead fish, the sewage pipes of the equipment may be blocked

The third is to occupy a large area of ​​water surface. The area of ​​circulating water in the pond is generally no more than 20% of the total area of ​​the pond. The rest of the pond water surface needs to be used to plant water purification plants to treat the water quality of the aquaculture, otherwise it cannot meet the water requirements of the pond runway fish culture.

[0005] However, traditional pond aquaculture is also faced with the difficulty of changing the nature of the land and the strict discharge of tail water. There is little room for improvement in aquaculture production, which restricts the further development of my country's aquaculture industry to a certain extent.
