为使垃圾渗沥液全盐量的测定方法快速、简便，以国家标准方法———重量法为参照，对10组渗沥液水样的电导率进行测定，建立全盐量和电导率的回归方程，并进行相关性分析。结果表明：2种测定方法建立的渗沥液全盐量回归方程为y=0.58x-0.42，相关系数r=0.9997，标准差SD=0.047，线性关系较好。在一定条件下，可通过回归方程直接将电导率测试值转换为垃圾渗沥液全盐量，实现速测。但由于渗沥液的产生源、季节变化等原因，应对该方程进行相应的修正。%To find out a fast, easy determination of total salt content for waste leachate, taking gravimetric method (national standard method) as a reference, the conductivity of 10 groups of leachate samples was measured to establish regression equation between conductivity and total salt content, and their correlation was analyzed. The results showed that the regression equation of total salt content for waste leachate based on two measuring methods is y=0. 58x-0. 42, r=0. 999 7, SD=0. 047. They have higher linearity. Under certain conditions, the test value of conductivity can be directly converted into total salt content of waste leachate though the regression equation to actualize quick test. However, due to generation source, seasonal changes and other reasons of leachate, this regression equation should be relevant revised.
