The results showed that at the anaerobic phase, the PHB concentration in the cell and orthophosphate concentration of the anaerobic effluent obviously increased, the poly-P concentration in the cell decreased, and the cucci and bacilli with a size of 1.0~1.5 μm were dominant and formed grapy cellular cluster. At the anoxic phase, the PHB concentration and orthophosphate concentration decreased significantly, the amount of poly-P increased, and the elliptical cucci of 0.5~1 μm and spheral bacilli of 1.0~1.5 μm were dominant. At the aerobic phase, the PHB and orthophosphate concentration almost reduced to zero, the poly-P increased significantly, cucci appeared single or in pair, and the contour of sphere was blur and almost disappeared.
