In this study, a fixed bed bioreactor filled with biopolymer polycaprolactone (PCL) was developed to remove nitrate from groundwater through denitrification. PCL serves both as carbon source and biofilm carriers. During a long-term operation of 561 d, the performance of the reactor in nitrogen removal, characteristics of biofilm attached to biodegradable carriers, and the hydrolysis and utilization of solid carbon source were studied. With temperatures exceeding 24 °C, the average nitrate… CONTINUE READING
