| 摘 要： | 在CSTR和间歇操作两种模式下考察了早、晚期渗液水质特性在Fenton处理过程前后的变化。结果表明NH2－N，NO3－N，Cl^-质量浓度变化很小，F－质量浓度则有较大的增加，而IC（无机碳）值下降较多，渗滤液中的CODCr和TOC均得到不同程度的去除，且晚期渗滤液的去除率高些，造成这些不同处理效果的原因主要是渗滤液中高分子量有机物（High Molecular Weight Organic Matter,HMWOM)与低分子量有机物（Low Molecular Weight Organic Matter,LMWOM)的比例存在较大的差异，此外，文中CODCr和TOC的去除率大多低于文献1]的数值。

| Abstract: | Both CSTR and batch mode were employed to investigate the variation of young and old landfill leachate characteristics during Fenton process.It was shown that ammonia\|nitrogen,nitrate\|nitrogen and chloride changed little after treatment.The fluoride concentration increased greatly and the removal of IC was very high during the process.COD and TOC decreased after Fenton process.Moreover,the percentage of COD and TOC removal from old leachate was slightly greater than that from young leachate.This was mainly due to the diferent HMWOM to LMWOM ratio in different landfill leachate.In addition,most of the removal efficiencies in this work were lower than those achieved in reference. |
