New composite materials to remediate nitrate contaminated groundwater by sulfur-based autotrophic denitrification

摘要

Nitrate in synthetic groundwater could be effectively reduced and the system exhibited stable pH using composite materials, which could provide the electron donor, inorganic carbon source and sufficient alkalinity all at once for sulfur-based denitrification. All these results indicate the potential of the composite materials for remediation of nitrate-contaminated groundwater.
