Application of mathematical model in wastewater treatment optimal control

A mathematical model for activated sludge system was constructed based on ASM2. State Point Analysis was used to analyze the condition of the Secondary Settling Tanks of the Yinchuan wastewater treatment plant. And the predicted results accorded with the actuality. In addition, we changed the MLSS and the ratio of the circumfluence in order to improve the quality of the effluent. Mathematical simulation of activated sludge system model has certain effects for operation management and technological transformation.
