摘要
以来自中国三个不同城市的垃圾渗滤液为研究对象,讨论高铁酸盐对垃圾渗滤液的处理效果。在讨论常规水质参数如COD、TOC、总氮、总磷、氨氮和BOD5的处理前后的变化外,利用紫外光谱和三维荧光光谱对垃圾渗滤液进行对照分析。紫外光谱表明高铁酸盐对LL3型号的垃圾渗滤液处理效果最为明显,同时对比不同反应时间下UV254的响应度和TOC的变化,结果表明UV254能够较好的指代水体污染物。三维荧光光谱分析表明,三种垃圾渗滤液中均含有类腐殖酸和类蛋白质等物质,并且经高铁氧化反应后,均得到明显降解。
The treatment effect of ferrate on landfill leachate from three different cities in China was discussed.In addition to discussing the changes of conventional water quality parameters such as COD,TOC,TN,TP,NH4-N and BOD5 before and after treatment,the comparison analysis of landfill leachate was carried out by using ultraviolet spectrum and three-dimensional fluorescence spectrum.The UV spectrum showed that ferrate has the most obvious effect on LL3 of landfill leachate.Meanwhile,the corresponding degree of UV254 and the change of TOC under different reaction time were discussed,and the results showed that UV254 can better represent water pollutants.Three-dimensional fluorescence spectrum analysis showed that the three kinds of landfill leachate contained humic acid and protein-like substances,and they were obviously degraded after ferrate treatment.
