    Abstract:

    A bacterial strain P10 with better phosphorus removal performance was isolated from the excess sludge in a sedimentation basin of a laboratory scale A/O reactor with stable performance.The optimum pH of growth and initial phosphorus removal for the bacterium are 6.5 and 6.0,respectively.The optimum temperature for cell growth and phosphorus removal are at 30 ℃.Ferrous,manganese and copper ions can stimulate bacterial growth.Moreover,ferrous and manganese ions also promote the phosphorus removal.The addition of ferrous ions could increase the cell concentration by 8.1% and the phosphorus removal amount by 46.0%.The highest removal rate could be reached(up to 11.23 mg/(g·h)) with the phosphorus in form of dipotassium hydrogen phosphate.
