Abstract:
Taking the main urban area of Quanzhou as the research object, this study systematically explores the implementation pathways and key focuses for urban sewage quality and efficiency improvement. It proposes a governance philosophy of “smart coordination, investigation first, design-led, phased construction, designated maintenance”. By constructing an integrated platform of the “water management brain” to consolidate multi-source data, and based on the findings of a comprehensive drainage system investigation and diagnosis, the sewage quality and efficiency improvement plan for Quanzhou is deployed from a planning and design perspective. Priority construction is given to critical nodes, concentrated operations are conducted in key areas, and a dedicated district-level maintenance mechanism for drainage facilities is established. This project has effectively enhanced the efficiency of sewage collection and treatment and improved the water quality of inner river channels in the main urban area of Quanzhou, providing a replicable practical paradigm for similar urban sewage quality and efficiency improvement projects.
