Description

technical field [0001] The invention relates to a marine product cultivation system, and specifically relates to a seawater circulation cultivation and seedling cultivation system for a workshop. Background technique [0002] Domestic mariculture and nursery are mostly relatively extensive mariculture, with a large scale, and a large amount of pollutants such as suspended particles, aquatic phytoplankton, etc. will be produced during the aquaculture process, and the daily drainage volume is large, but the waste water is basically If it is directly discharged into the surrounding sea area without purification treatment, it will cause great damage to the environment of the surrounding sea area. In severe cases, it will cause red tides, causing serious pollution to the environment and serious economic losses. The seawater nursery workshop of extensive seawater aquaculture is basically in a relatively low-level manual state for production and management. [0003] The invention ...

AI Technical Summary

Problems solved by technology

Although this equipment can reduce the input cost of mariculture and the energy consumption in the breeding process, and improve the utilization rate of seawater resources, the structural design of the equipment is unreasonable, the treatment process for aquaculture wastewater is complicated, and the heat source is single and difficult to use, which cannot achieve Rational use of energy and reduction of water consumption
