摘要：
I studied the stoichiometry and kinetics of acetate on anaerobic/aerobic (AnA) and completely aerobic (CA) sequencing batch rectors under nutrient-limiting conditions. CA acetate removal rates were 20 to 40% higher than AnA acetate removal rates when both nitrogen and phosphorus (P) were sufficient. When P was deficient, the acetate removal rate of both sludges was 0.8 mg acetic acid/g VSS/min. Anaerobic stoichiometry indicated that polyphosphate accumulating organisms were present at a low-level, and that glycogen-accumulating organisms were dominant. I also found that the AnA sludge synthesised 2 to 5 times more polyhydroxybutyrate C than the CA sludge.
