【Abstract】 Based on the activated sludge model NO.1(ASM1) and Takacs secondary clarifier model, a simulator was developed with reactor principle by compiling computer programs. Simulating process and mass balance for components in the biological reactor and second settling were analyzed. The time step of Eular integration was studied. The adjusted results show that methods used in the simulator were reliable. The developed simulator can be used as a useful tool for process design and prediction.更多还原
