A kinetic model for shortcut nitrification-denitrification process with sequencing batch reactor (SBR) was developed. To test this model, the kinetic parameters of the model including maximum specific rates and half-maximum rate concentrations for shortcut nitrification and denitrification were estimated from the results obtained from a laboratory-scale SBR fed with a soybean curd processing wastewater (400-800 mg COD L(-1), 50-65 mg NH(4)(+)-N L(-1)) at 26 degrees C. In the nitrification step, two DO levels (0.5 and 3.5 mg L(-1)) were tested and the predicated nitrification rates under different NH(4)(+)-N concentrations using this model fit well with correlation coefficient R = 0.9902. In the denitrification step, the process of nitrite removal was close to a zero-order reaction if the concentration of electron donor was not so low (COD > 100 mg L(-1)), and concentrations of nitrite and organic matter (as COD) had limited effect on denitrification rate. The model can be used to predict nitrogen removal performance with different influent NH(4)(+)-N and COD concentrations and under various DO concentrations.
