AI Technical Summary
Existing crab farming systems are prone to the accumulation of ammonia nitrogen and nitrite and fluctuations in dissolved oxygen under high-density conditions, resulting in poor water stability. Furthermore, the wastewater from these systems is discharged without effective treatment, making it difficult to meet environmental regulatory requirements.
The system employs a dual-circulation coupling subsystem and an ecological device combination subsystem, combined with an unattended intelligent control subsystem, to achieve external circulation purification and reprocessing, internal closed-loop purification, and re-purification of aquaculture water. Through intelligent monitoring and linkage control, it reduces fugitive emissions, lowers pollutant accumulation, and improves water stability.
It achieves efficient purification of aquaculture water, reduces fugitive emissions, improves system purification efficiency and operational reliability, and ensures the sustainability and safety of the aquatic environment.
