The exponential generation of municipal solid waste (MSW) and landfill disposal without any treatment has increased the continuous generation of landfill leachate. Improper MSW and leachate management are contributing to environmental degradation and water and soil pollution, which must be treated. Numerous works have been conducted on leachate treatments for energy and resource recovery. This review presents a comprehensive study of leachate management in which different treatment methods are discussed to analyze the suitability of processes that can be employed to treat leachate efficiently. Further, the characteristics of leachate are examined as properties of leachate may be varied depending upon the region. Still, several challenges related to leachate management and its treatments are discussed in this study. An integrated system could be a better option for treating leachate because it contains large amounts of organic and inorganic compounds. Proper leachate management would help to recover energy and value-added products (metals).
城市固体废物（MSW）的指数级产生和未经任何处理的垃圾填埋处置导致了不断产生的垃圾渗滤液。不适当的 MSW 和渗滤液管理正在导致环境恶化以及水和土壤污染，这些问题必须得到处理。已经有许多关于渗滤液处理以实现能源和资源回收的工作。本综述对渗滤液管理进行了全面研究，讨论了不同的处理方法，以分析可用于有效处理渗滤液的工艺的适用性。此外，还研究了渗滤液的特性，因为渗滤液的特性可能因地区而异。尽管如此，本研究还是讨论了与渗滤液管理及其处理相关的几个挑战。对于处理渗滤液，集成系统可能是一个更好的选择，因为它含有大量的有机和无机化合物。适当的渗滤液管理将有助于回收能源和增值产品（金属）。
