Aquaculture Solutions

The autotrophic deep nitrogen removal technology of Yusuoqiu is an emerging technology that achieves deep nitrogen removal by combining highly efficient microbial strains developed by the State Key Laboratory of Huazhong Agricultural University with new fillers. This technology utilizes autotrophic denitrifying bacteria, which can use reduced sulfur as an electron donor under aerobic conditions to obtain energy through the oxidation-reduction of sulfur. At the same time, they use nitrate as an electron acceptor to reduce it to nitrogen gas, thereby achieving deep denitrification of wastewater. This technology further integrates with the existing sewage treatment processes to ultimately achieve the standard discharge of aquaculture tail water. Among them, sulfur autotrophic denitrification serves as the core process, which features low cost per ton of water, low sludge production, and no consumption of carbon sources.
