Research on parameters relationship of MBR in practical application

As the complexity of the process of MBR industrial wastewater treatment, most of its parameters are nonlinear and uncertain characteristics, but they can be a regression model under certain conditions. With the engineering data from a MBR wastewater treatment plant in Shijiazhuang City for three months, we combine three of the indicators in its process, COD, TN, and TP, then get the regression model after making the linear fit and quadratic fit and comparison of goodness of fits, which proves its consistency with actual projects and is profoundly instructive on MBR research.
