The dechlorination and biodegradation of PCP by anaerobic granular sludge
Experiments conducted on batch serum bottle have confirmed that anaerobic granular sludge AGS<sub>R1</sub> and AGS<sub>R2</sub> are capable of sequentially degrading PCP to form 2, 4, 6-TCP 2,4-DCP and 4-CP with higher dechlorination activity, and indicated preferential dechl...

| Summary: | Experiments conducted on batch serum bottle have confirmed that anaerobic granular sludge AGS<sub>R1</sub> and AGS<sub>R2</sub> are capable of sequentially degrading PCP to form 2, 4, 6-TCP 2,4-DCP and 4-CP with higher dechlorination activity, and indicated preferential dechlorination at meta. and ortho position. By analyzing dechlorinating intermediates, the pathway of PCP degradation have been proposed, it is found that the modified Monod model could be used to describe the PCP degradation. Addition of electron donor such as butyrate and glucose enhanced dechlorinative degradation of PCP. In the presence of butyrate the para -dechlorinating activity in AGS<sub>R1</sub> is induced, PCP dechlorination by anaerobic granules is best described by pseudo first-order kinetics. The rate constant of PCP degradation is increased with increasing concentration of butyrate. |
