ABSTRACT
With the acceleration of urbanization and population growth, the treatment of landfill leachate has become a critical issue in global environmental protection. The high concentrations of organic matter, ammonia nitrogen, and heavy me tals in leachate pose serious threats to ecological environments. This study aims to explore efficient and cost-effective leachate treatment technologies to address the contradiction between cost control and pollutant removal efficiency in traditional processes. By combining laboratory simulations with field experiments, the feasibility and performance of the combined anaerobic-aerobic biological treatment and advanced oxidation process (A/O-AOP) were systematically evaluated for practical applications. The results indicate that this integrated process significantly reduces chemical oxygen demand (COD), ammonia nitrogen (NH4+-N), and total nitrogen (TN) in leachate, ensuring effluent compliance with the "Pollution Control Standard for Domestic Waste Landfills" (GB 16889-2008). Specifically, the anaerobic stage effectively degrades large molecular organic compounds, enhancing the biodegradability of wastewater; the aerobic stage further removes dissolved organic matter and ammonia nitrogen; and the advanced oxidation process serves as a tertiary treatment method to ensure the complete mineralization of refractory organic pollutants. Additionally, this study innovatively applies response surface methodology to optimize process parameters, clarifying the interactions among various factors and their impacts on treatment efficiency. The final outcomes demonstrate that the optimized A/O-AOP process exhibits significant advantages in operational stability and economic viability, providing new insights and feasible solutions for addressing the challenges associated with landfill leachate treatment.
