【Abstract】 The kinetics of growth rates of microorganisms, the rates of nitrification and denitrification which applied in biological wastewater treatment of sequential fed-batch reactor were studied. The growth rate of microorganisms, the rates of nitrification and denitrification,the rates of reaction for readily biodegradable substrate and their material balance in aerobic and anoxic period were developed, respectively, according to the principle and result in activated sludge model No. 1 (ASM1).The adequate methods of parameter estimation were adopted from the experiment results. The group of differential equations was dissolved with Ronge-Kutta method and minimum error was searched with Gold Division method on the base of experimental result. The minimum error ε was about 4.799. The value of kinetics parameters and stoichiometric coefficient such as μ_A、μ_H、Y_A 、Y_H 、K_S 、K_ NO 、K_ NH、K_ OA、K_ OH in the model were estimated and parameters in the model were estimated from the result of the experiment.更多还原
