An eco-friendly recirculating and filtering aquaculture system based on salinity tolerant aerobic granular sludge

摘要

The present invention relates to an eco-friendly circulating filtration aquaculture system based on salt-resistant aerobic granule sludge for use of aquaculture water without discharge from aquaculture farms. The system efficiently treats organic matters and ammonia nitrogen from feed residues and wastes generated during aquaculture by injecting salt-resistant aerobic granule sludge into aquaculture and denitrification tanks.
