Researchers have documented the negative effects of refractory chemicals and emergent pollutants in landfill leachate (LL) that cannot be degraded using conventional methods. The propagation, invasion, and deleterious effects of several LL hazards affect aquatic species, the environment, and food outlets, causing significant safety issues. These include cancer risks, chronic exposure, and reproductive consequences. Alternatively, solar energy is a sustainable solution for treating landfill leachate to benefit humans and the environment. In this work, a thorough bibliometric and systematic analysis of studies that employed solar energy for landfill leachate remediation over the past decade was conducted in order to determine trends, and future research areas. In addition to the energy demand, the economic aspect and the advantages of using solar power to treat landfill leachate were discussed. Additionally, the study gives specific suggestions for future research purposes and important problems. The reviewed literature revealed that combining solar-based physical-chemical and biological processes has proven to be the most efficient method for landfill leachate degradation. It also appears from the bibliometric study that more collaboration and contribution are needed to develop solar-based landfill leachate treatment. This study concludes that solar-powered landfill leachate remediation techniques would considerably increase the effectiveness of treated leachate reutilization, advancing the cause of environmental sustainability.
研究人员记录了垃圾渗滤液（LL）中无法通过常规方法降解的难处理化学物质和新兴污染物的负面影响。一些 LL 危害的传播、入侵和有害影响会影响水生物种、环境和食品供应渠道，造成重大安全问题。其中包括癌症风险、慢性暴露和生殖后果。另一方面，太阳能是处理垃圾渗滤液的可持续解决方案，有利于人类和环境。在这项工作中，对过去十年中利用太阳能修复垃圾渗滤液的研究进行了全面的文献计量和系统分析，以确定趋势和未来的研究领域。除了能源需求外，还讨论了使用太阳能处理垃圾渗滤液的经济方面和优势。此外，该研究还为未来的研究目的和重要问题提出了具体建议。文献回顾表明，结合基于太阳能的物理化学和生物过程已被证明是降解垃圾渗滤液最有效的方法。从文献计量研究中还可以看出，需要更多的合作和贡献来开发基于太阳能的垃圾渗滤液处理技术。本研究得出结论，太阳能驱动的垃圾渗滤液修复技术将大大提高处理后渗滤液再利用的效果，推进环境可持续发展事业。
