Research on Water Purification Equipment Technology of Circulating Aquaculture System

The circulating aquaculture system is the current development direction of advanced aquaculture productivity, it has the characteristics of highly controllable aquaculture environment, safe and reliable product quality, water saving and land saving, and could meet the country’s strategic needs of transforming economic growth and saving energy and reducing emissions. Water purification equipment for circulating water aquaculture is the core component of circulating water aquaculture system, it provides good aquatic environment for aquaculture objects in circulating aquaculture production, improves the output and quality of aquaculture products, and promotes resource utilization. This article took the typical water purification technology of circulating aquaculture system as the main line, discussed and summarized the equipment technologies involved in the removal of suspended matter, degradation of dissolved organic matter, sterilization, aeration and temperature regulation, and proposed development suggestions, aiming to build a precise, efficient and energy-saving circular aquaculture system, and provide support for its further application.
