摘要
通过简化传统的ASM1污泥活性模型提取出污泥和污水中底物的非线性动力学作用关系,建立一个适用于膜生物反应器的简化二维数学模型。通过修正原模型参数,该模型能和实验数据吻合良好,证明了该模型的有效性。在此基础上从非线性动力学的角度对数学模型进行有界性和稳定性的验证和分析,从理论的角度提出了模型参数选取的范围。
A two-dimensional mathematical model for membrane bioreactor （MBR） was set up by simplifying the dynamical relations in ASM1 active sludge model. With some new parameter combinations,the simulation results fit the testing data well,so the accuracy of this model was proved. Then the boundedness and the stability of this model was analyzed in the view of nonlinear dynamics,and the choice region of the parameters was gained theoretically.
