The variations in N, P and COD, chlorophyll content, environmental parameters were monitored under long-term batch operation (80 days). The synergistic interaction, N and P removal processes, microbial community structure, functional genes and metabolites were determined to thoroughly understand the feasibility of H2-IBAB. This work provides an alternative technology for achieving low-carbon and advanced wastewater treatment, which contributes to promoting the development of algae and bacteria membrane biofilm units under strict wastewater discharge standards.ENAfalsemetagenome hydrogen bacteria2024-06-202024-06-20PRJNA1125159
