ABSTRACT
With the acceleration of urbanization, the treatment of municipal solid waste (MSW) has become a global environmental concern. Traditional landfill methods face challenges such as limited land resources and secondary pollution, while incineration for power generation has attracted significant attention due to its advantages in efficient volume reduction and resource recovery. This study focuses on optimizing MSW incineration technology and evaluating its environmental impacts through an integrated approach combining experimental analysis, numerical simulation, and life cycle assessment. The research systematically investigates the influence of key parameters during incineration, including temperature, residence time, and oxygen supply, on combustion efficiency and pollutant emissions. Advanced flue gas purification technologies and thermal energy recovery schemes are introduced, significantly enhancing energy utilization efficiency and reducing the emissions of harmful substances such as dioxins and heavy me tals. Results indicate that the optimized incineration process achieves a waste volume reduction rate exceeding 90%, increases power generation efficiency to 25%, and reduces the carbon dioxide equivalent emissions per unit of waste incinerated by approximately 30%. Additionally, life cycle assessment reveals that, despite certain environmental burdens associated with incineration, the comprehensive environmental benefits surpass those of traditional landfill methods when synergistic control strategies and technological improvements are implemented. A major innovation of this study lies in the proposal of a multi-ob jective协同optimization model that integrates the enhancement of energy efficiency with pollutant reduction, providing scientific support for policymakers and promoting the transition of MSW management towards low-carbon, environmentally friendly, and sustainable development. The findings offer valuable references for advancing the engineering application of incineration power generation technology and improving environmental management practices.
