Abstract

With the acceleration of urbanization and the enhancement of ecological and environmental protection requirements, urban wastewater treatment plants are facing dual pressures from treatment capacity and discharge standards. Upgrading technological paths has become a key direction for achieving standard discharge and resource utilization. By analyzing mainstream upgrading and renovation technologies, including standards improvement, advanced treatment, and sludge collaborative disposal, combined with process flow optimization and intelligent management measures, this study explores the adaptability of technology selection and implementation paths. The research results indicate that a diverse, synergistic, and greenly efficient technology combination helps achieve a low-carbon, sustainable wastewater treatment system, enhancing the urban water environment quality and system operational efficiency.
