摘要

A number of analytical measurement were used to determine the potential for enhancedrnbiological phosphorus removal (EBPR) in sewage treatment works (STW). Wastewatersrnstudied comprised both municipal and industrial wastewaters and were analysed forrndiverse parameters such as organic and phosphorus content, septicity, temperature andrnpH. Two methods to determine the amount of substrate available for EBPR, the readilyrnbiodegradable COD and the VFA potential, were used and compared. The VFArnpotential method was simplified in terms of samples preservation and pH measurementrnwas used throughout the test to control its duration. Volatile fatty acid (VFA)rnproduction rates and VFA potential to phosphorus ratio were compared to thernperformance of the STW for BPR. For higher rates and ratios a better performance inrnterms of phosphorus removal was observed, indicating a clear correlation with thernwastewater characteristics studied.
