摘要：

The immediate maximum specific oxygen uptake rate (SOUR(im)) was investigated as a potential process control parameter for the activated sludge system. Variability in effluent quality in terms of chemical oxygen demand correlated very well with the levels of SOUR(im) at cell residence times of 3, 5, and 10 days. Transient response studied under batch growth conditions indicated a strong correlation between the SOUR(im), chemical oxygen demand, and the ribonucleic acid rates of change. The SOUR(im) can therefore be used to qualitatively and quantitatively describe a given biomass thus making it a better suited parameter for use in process control strategies.
