摘要:

通过水热反应及高温烧结制备了Gd/Fe-C材料,探究了Gd/Fe-C材料对老龄垃圾渗滤液的降解效果,并分析了老龄垃圾渗滤液的组成成分。结果表明,Gd/Fe-C材料处理垃圾渗滤液对COD、TOC、UV254降解率为69.75%、58.13%、95.52%,对色度的去除率为97.37%,老龄垃圾渗滤液中的主要成分为类富里酸和类胡敏酸。经处理后,大部分的类富里酸被降解,芳香族不饱和度和腐殖化程度降低,可生化性提高,更容易被生物吸收利用。

Abstract:

Gd/Fe-C composite material was prepared through hydrothermal reaction and high-temperature sintering, and its degradation effect on the leachate of aging garbage leachate was investigated. The components of the leachate were analyzed. The results showed that COD, TOC and UV254 degradation rates were 69.75%, 58.13% and 95.52% of landfill leachate treated with Gd/Fe-C material, and the removal rates of chroma were 97.37%. The main components of the aged landfill leachate were fulvic-like acids and humic acid. After treatment, most fulvic-like acids were degraded, and the degree of aromatic unsaturation and humus decreased. The biodegradability is improved, and it is easier to be absorbed and utilized by biology.

Key words: composite material, landfill leachate, three-dimensional excitation and emission matrix(3D-EEM)
