Abstract: As the core infrastructure for water pollution control, the operation and management level of sewage treatment plants directly determines the efficiency of pollutant reduction. At the same time, the entire operation process is accompanied by secondary environmental impacts such as odor emissions, noise interference, and improper sludge disposal. There is an inherent relationship of in-depth symbiosis and collaborative promotion between operation control and environmental protection. Based on the actual operation management and environmental control practice of sewage treatment plants, this paper systematically sorts out the core content of operation management and the transmission mechanism of environmental impact, comprehensively identifies core environmental issues such as tail water discharge, odor pollution, noise interference, and sludge disposal, and deeply analyzes the pain points restricting collaborative development, such as extensive operation control, disconnection between processes and environmental protection needs, low resource recycling rate, and insufficient intelligence level. From the five dimensions of refined operation, whole-process environmental control, energy-saving and low-carbon operation, resource recycling, and digital intelligent upgrading, a collaborative optimization system for operation management and environmental protection is constructed, and the practical direction and implementation value of various optimization paths are clarified. The research shows that fully integrating the concept of environmental control into the entire operation process, implementing whole-process refined control and digital empowerment, and simultaneously implementing measures such as sludge resource utilization and energy recovery can minimize the negative environmental impacts during operation on the premise of ensuring sewage treatment efficiency and stable effluent compliance, realize the organic unity of environmental, economic and social benefits, and provide practical reference for the quality improvement, efficiency enhancement and green transformation of urban sewage treatment plants.
