超临界水氧化处理垃圾渗滤液的研究进展

摘要

Supercritical water is known as the perfect medium of disposing landfill leachate for its special properties. However, corrosion on the material of reactors limits its further application. Nickel-base alloy as the corrosion-resistant material for supercritical water oxidation process has been widely used; it shows the good corrosion resistance and economy, compared to other materials.%超临界水氧化（SCWO）技术是利用超临界水表现的特殊性质而作为垃圾渗滤液处理的理想媒介。但其在应用过程中对反应器壁材料的严重腐蚀问题阻碍了其广泛的工业化应用并成为研究的热点。镍基合金作为超临界水氧化过程的耐腐材料被广泛的应用于研究中，与其他材料相比，表现出了良好的抗腐蚀性能和经济性。
