The experimental results indicate that PLA/PHBV is degraded more rapidly and easily than PLA and PCL. PLA is difficult to be degraded in water solution, so it is unsuitable to be used as carbon source for denitrification. Average denitrification rates supported by PCL and PLA/PHBV were 6.34 and 6.63 mg L-1 h-1 with 7 h HRT under a batch system, respectively. Nitrite was not detected in the treated water after 9-hour operation. CARBON SOURCE GROUNDWATER NITRATE DENITRIFICATION BIODEGRADABLE POLYMERS Honda, Y.
