摘　　要：Cultivation of aerobic granular sludge for pentachlorophenol(PCP) degradation under microaerobic condition(DO concentration was controlled at 0.2—0.7 mg/L) was studied in this paper. Anaerobic granules were selected as inoculum. The changes of appearance were observed and the variations of SVI, VSS/TSS, PN/PS and the size of sludge were measured during cultivating. The capabilities for degradation of PCP, AOX and COD_ Cr were also studied. Observations on mature granules were carried out by scanning electron microscope, and the results indicated bacillus was dominant on the surface of granules while in the inner of granules both bacillus and coccus were the dominant microorganisms. K, Na, Fe, Ca, Mg, Ni, Co, Mn, Cu and Zn were detected in the granules by element analysis.Cultivation of aerobic granular sludge for pentachlorophenol(PCP) degradation under microaerobic condition(DO concentration was controlled at 0.2—0.7 mg/L) was studied in this paper.
