Sanitary landfill is the most popular way to dispose solid wastes with one major drawback: the generation of landfill leachate resulting from percolation of rainfall through exposed landfill areas or infiltration of groundwater into the landfill. The landfill leachate impacts on the environment has forced authorities to stipulate more stringent requirements for pollution control, generating the need for innovative technologies to eliminate waste degradation by-products incorporated in the leachate. Natural attenuation has no effect while conventional treatment processes are not capable of removing some the pollutants contained in the leachate which are reported to reach the natural environment, the aquatic food web, and the anthroposphere. This review critically evaluates the state-of-the-art engineered materials and technologies for the treatment of landfill leachate with the potential for real-scale application. The study outcomes confirmed that only a limited number of studies are available for providing new information about novel materials or technologies suitable for application in the removal of pollutants from landfill leachate. This paper focuses on the type of pollutants being removed, the process conditions and the outcomes reported in the literature. The emerging trends are also highlighted as well as the identification of current knowledge gaps and future research directions along with recommendations related to the application of available technologies for landfill leachate treatment.

垃圾渗滤液处理的新兴材料和技术:批判性评论

卫生垃圾填埋场是处理固体废物的最流行方式,但存在一个主要缺点:雨水渗入暴露的垃圾填埋场或地下水渗入垃圾填埋场,会产生垃圾渗滤液。垃圾渗滤液对环境的影响迫使当局制定更严格的污染控制要求,从而需要创新技术来消除渗滤液中的废物降解副产品。自然衰减没有影响,而传统的处理过程无法去除渗滤液中所含的一些污染物,据报道这些污染物会到达自然环境、水生食物网和人类圈。这篇综述批判性地评估了最先进的工程材料和技术,用于处理垃圾渗滤液,具有实际规模应用的潜力。研究结果证实,只有有限数量的研究可用于提供有关适用于从垃圾渗滤液中去除污染物的新材料或技术的新信息。本文重点介绍被去除的污染物类型、工艺条件和文献中报告的结果。还强调了新兴趋势以及确定当前知识差距和未来研究方向,以及与垃圾渗滤液处理可用技术应用相关的建议。研究结果证实,只有有限数量的研究可用于提供有关适用于从垃圾渗滤液中去除污染物的新材料或技术的新信息。本文重点介绍被去除的污染物类型、工艺条件和文献中报告的结果。还强调了新兴趋势以及确定当前知识差距和未来研究方向,以及与垃圾渗滤液处理可用技术应用相关的建议。研究结果证实,只有有限数量的研究可用于提供有关适用于从垃圾渗滤液中去除污染物的新材料或技术的新信息。本文重点介绍被去除的污染物类型、工艺条件和文献中报告的结果。还强调了新兴趋势以及确定当前知识差距和未来研究方向,以及与垃圾渗滤液处理可用技术应用相关的建议。本文重点介绍被去除的污染物类型、工艺条件和文献中报告的结果。还强调了新兴趋势以及确定当前知识差距和未来研究方向,以及与垃圾渗滤液处理可用技术应用相关的建议。本文重点介绍被去除的污染物类型、工艺条件和文献中报告的结果。还强调了新兴趋势以及确定当前知识差距和未来研究方向,以及与垃圾渗滤液处理可用技术应用相关的建议。
