ABSTRACT:
In order to provide a safe means for the direct purification of groundwater, which enables the efficient use of carbon source and the concentration of nitrificans, while requiring no addition of heavy metals, a starch-derived biodegradable plastic is used as a single carbon source and immobilizing carrier of denitrificans, and contacted with nitrate-polluted groundwater.
