Studies on formation of aerobic granular sludge for pentachlorophenol (PCP) degradation under microaerobic condition are carried out (DO concentration is controlled at 0.2～0.7 mg/L). Anaerobic granules are selected as seed sludge. The changes of appearance are observed and the variations of SVI, VSS/TSS, PN/PS and the size of sludge are measured during culture. The capabilities for degradation of PCP, AOX and COD_ Cr are also studied.
