摘要
用标准法和快速法测定了垃圾渗滤液的CODCr,结果分别为2018mg/L和2074mg/L,平均值为2046mg/L,相对标准偏差分别为2.5%和3.0%.用Origin7.0专业数据分析和绘图软件对测定结果进行了方差分析,结果表明,在规定的0.05显著性水平上,标准法和快速法没有明显的差异,说明快速法测定垃圾渗滤液的CODCr是可靠的.
Standard method and rapid method have been used for the determination of COD_(Cr) in landfill leachate.The results are 2018 mg/L and 2074 mg/L respectively. The average value of COD_(Cr) is 2046 mg/L, with 2.5% and 3.0% RSD respectively.The results of ANOVA by analysis software Origin 7.0 show that the rapid method is reliable,as the population means of two selected methods are not significantly different at the 0.05 level.
