Aquaculture wastewater is rich in nutrients such as nitrogen and phosphorus. If discharged directly without treatment, it can cause eutrophication of water bodies the proliferation algae. This study explores treatment aquaculture using cerium nitrate hydrogen peroxide. To improve efficiency ammonia nitrite wastewater, a Box–Behnken design with three factors at levels was used to optimize process treating The optimal conditions for removing were determined be Ce(NO3)3 dosage 0.18 g/L, an H2O2 reaction concentration 1.0%, time 30 min. Under conditions, degradation rate reach 80% or more. Finally, high-throughput sequencing technology explore impact peroxide on microbial community structure metabolic pathways. results showed that, phylum level, dominant positions Actinobacteriota, Proteobacteria, Bacteroidota maintained throughout entire culture period. At genus relative abundance hgcI_clade under Actinobacteriota significantly increased, becoming main condition adding peroxide, functions enhanced. addition increased key metabolism genes amo, hao, nap, thereby enhancing potential nitrification/denitrification capabilities microorganisms. combination positive effects providing new strategy green wastewater.
