摘 要
随着城市化进程的加快和垃圾填埋量的持续增长，垃圾填埋场渗滤液的处理已成为环境工程领域的重要课题。渗滤液成分复杂、污染物浓度高且波动性大，其有效处理直接关系到生态环境保护与可持续发展目标的实现。本研究旨在探讨并优化垃圾填埋场渗滤液处理技术，以提高处理效率并降低运行成本。通过实验室模拟与现场试验相结合的方式，选取多种主流处理工艺进行对比分析，包括生物处理、膜分离、高级氧化及组合工艺等，并结合水质特征提出针对性优化方案。研究结果表明，采用“厌氧-好氧生物处理+纳滤膜分离+芬顿氧化”组合工艺可显著提升渗滤液中COD、氨氮和重金属的去除率。

Abstract
With the acceleration of urbanization process and the continuous growth of landfill volume, the treatment of landfill leachate has become an important topic in the field of environmental engineering. The leachate has complex composition, high pollutant concentration and high volatility, and its effective treatment is directly related to the ecological environment protection and the realization of sustainable development goals. This study aims to explore and optimize landfill leachate treatment techniques to improve treatment efficiency and reduce operating costs. Through the combination of laboratory simulation and field test, a variety of mainstream treatment processes are selected for comparative analysis, including biological treatment, membrane separation, advanced oxidation and combination process, etc., and the targeted optimization scheme is put forward combined with the water quality characteristics. The results show that the combined process of "anaerobic-aerobic biological treatment + nanofiltration membrane separation + Fenton oxidation" can significantly improve the removal rate of COD, ammonia nitrogen and heavy me tals in the leachate.
