【摘要】 分别研究了紫外吸光度值UV254和△UV与垃圾渗滤液COD的关系,研究表明UV254和△UV与COD存在着很好的线性关系,并且UV254与COD的线性关系优于△UV与COD的线性关系。由于本法测定时水样无需预处理,简化了测定过程,因此UV254可以作为评估垃圾渗滤液COD的一种参数。更多还原

【Abstract】 The relationships of ultraviolet absorbancy UV254 and △UV with COD were studied respectively.The linear equation of UV254 and COD and the linear equation of △UV and COD were set up,and the former is more significant than the latter. Because this method can save time, manpower and without pretreatment, so UV254 could be used to assess the COD value of waste leachate as a parameter.更多还原
