摘要
针对潜水流湿地污水处理反应器模型,研究了当Michaelis-Menten方程近似为浓度的非线性(二次幂律)函数情况时的求解方法.利用Adomain拆分方法,得到了问题具有级数形式的近似解析解.本文所采用的方法和技巧可以用来解决当Michaelis-Menten方程近似为浓度的其他非线性函数情况.
The subsurface flow wetland reactor model for sewage treatment was studied by approximating the Michaelis-Menten equation into a nonlinear power law function of two orders. The analytical solutions were obtained in terms of a rapid convergent power series by utilizing the Adomain decomposition technique. The mathematical technique employed in this paper is also of significance in studying the problems when the Michaelis-Menten equation is approximated by other nonlinear functions.
