Abstract: This study aimed to apply a mathematical model of USTS based on the ecological restoration concept to optimise the urban sewage treatment process and improve treatment efficiency and environmental protection level. By analysing the structure and treatment process of USTS, a mathematical model of the sewage treatment system was established. The back propagation (BP) neural networks algorithm was used to train and optimise the model to improve its prediction and control capabilities. The effectiveness and reliability of the model were verified through practical application and validation. The experiment in this article showed that the reliability of the mathematical model of USTS based on ecological restoration concept was between 95%-98%, and the effectiveness of the mathematical model of USTS based on ecological restoration concept was between 93%-97%. The results show that the mathematical model of urban sewage treatment systems incorporating ecological restoration concepts can significantly reduce energy consumption and operating costs.

Keywords: urban sewage treatment; ecological restoration; mathematical models; sustainable utilisation; water quality improvement; back propagation; BP.
