ABSTRACT
Urban water supply systems, as critical infrastructure for ensuring residents' livelihoods and economic development, have increasingly drawn attention regarding water quality safety. With the acceleration of industrialization, worsening environmental pollution, and heightened public health awareness, traditional water supply technologies struggle to meet modern demands for water quality safety. This study aims to explore and optimize water quality safety assurance technologies tailored for urban water supply systems, addressing the complex and variable risks of source water contamination. By integrating theoretical analysis with experimental validation, a water quality monitoring and treatment system based on the multi-barrier concept was constructed. This system comprehensively employs physical, chemical, and biological treatment technologies to evaluate the removal efficiency of typical pollutants. Additionally, intelligent monitoring approaches were introduced, leading to the development of a real-time water quality early warning model that significantly enhances the responsiveness of water supply systems to sudden pollution events. The results indicate that the proposed integrated technical solution effectively reduces concentrations of organic compounds, heavy me tals, and microorganisms in water, ensuring effluent quality complies with national drinking water standards. Moreover, it demonstrates excellent stability and cost-effectiveness in practical engineering applications. The innovation of this study lies in the deep integration of traditional processes with modern information technology, proposing a robust and efficient water quality safety strategy adaptable to diverse conditions. This research not only provides technical references for relevant fields but also offers scientific evidence for policymakers to optimize water supply management measures, holding significant theoretical and practical implications for the sustainable development of urban water supply systems.
