Performance of sulfur-iron based autotrophic denitrification biofilters for the removal of nitrate and phosphate and mechanisms of electron competition at different S/N
{{output}}
The performance of nitrate and phosphate removal and the mechanism of electron competition in sulfur based (VR-BF) and sulfur-iron based autotrophic denitrification biofilters with sponge iron (SI) as iron substrate (SIVR-BF) were analyzed at different S/N. As... ...
