黄铁矿/缓释碳源复合填料的脱氮效能及微生物机制
Denitrification performance and microbial mechanism of pyrite/slow-release carbon source composite filler
Based on the synergistic electron-donating effect of pyrite,polycaprolactone (PCL),and corncob as slow-release carbon sources,five groups of ternary composite fillers with different ratios were prepared.Batch experiments were conducted to investigate the denitrification performance and microbial mechanism under influent C/N ratios of 5,3,and 0.The results show that the Py40 group with 40% pyrite exhibits the best denitrification efficiency.At a C/N ratio of 0,the total nitrogen (TN) removal efficiency remains stable at approximately 87%,and the effluent COD and S
