The subtask of the National Key R&D Program "Development of special water treatment equipment for shrimp and sea cucumber circulating aquaculture" completed the on-site acceptance

Recently, the sub-task of the National Key R&D Plan led by the scientific and technological innovation team of the factory circulating aquaculture equipment of the Institute of Fishing Machinery, "Development of special water treatment equipment for shrimp and sea cucumber circulating aquaculture", successfully completed the on-site acceptance
at the Aquaculture Ecological Engineering Experimental Research Base of Rudong Fishing Machinery Institute in Jiangsu 。 The acceptance expert group listened to the work report of the research group, inspected the operation of the research and development equipment on the spot, consulted the relevant materials, and after questioning, it was unanimously agreed that the rapid separation and removal device of rotary shrimp shell developed by the research group has a single removal rate of 97.
2% of solid substances such as shrimp shell, which effectively solves the problem of difficult removal of solid substances such as shrimp shells in the breeding pond and ensures the stable operation of the shrimp circulating water aquaculture system; The developed air-lifted sea cucumber dual-channel sewage discharge device and the high-efficiency tailwater treatment device based on PHBV/volcanic rock/pyrite synergistic strengthening process have a recycling rate of 96.
3% of the aquaculture water, which realizes the discharge of sea cucumber aquaculture tail water up to standard, and effectively solves the problem
of sea cucumber pond due to the difficulty of removing sea mud and other particles, which affects the healthy growth of sea cucumber.

 

This project is a sub-task of the National Key R&D Program "Research on Shrimp Ginseng Circulating Water Aquaculture Technology and Construction of Clean Production System" (2019YFD0900505), mainly aiming at the lack of efficient and economical aquaculture water treatment technology and equipment in China's factory circulating water aquaculture mode of shrimp and sea cucumber, which in turn restricts the rapid development of the industry, focusing on the shrimp and sea cucumber circulating water aquaculture system, through the research and development of new technologies and equipment for shrimp and sea cucumber circulating water treatment.
Improving the economic benefits and technical level of factory circulating aquaculture can provide a strong guarantee for
the healthy and sustainable development of China's shrimp and sea cucumber aquaculture industry.
