The following assumptions are uesd to evaluate the stoichiometry of biological phosphorus removal:(1)1.06g acetate/g bsCOD will be produced as most of the COD fermented will be converted to VFAs due to the low cell yield of the fermentation process ,(2) a cell yield of 0.30g VSS/g acetate ,and (3) a cell phosphorus content 0.3g P/g VSS. Using these assumptions,about 10g of bsCOD will be required to remove 1g of phosphorus by the biological storage mechanism. Other bCOD removal in the activated-sludge system will result in additional phosphorus removal by normal cell synthesis.
