糖厂废水COD与BOD相关性分析

在分析糖厂废水ＢＯＤ时，常常需要对同一水样进行多个稀释比例的测定，但有时实验仍会失败．本文通过对１３家糖厂废水的测定数据进行分析，建立了ＣＯＤ与ＢＯＤ的回归方程；通过回归方程可由ＣＯＤ值予估ＢＯＤ值，从而较准确地确定水样稀释倍数，提高实验的成功率

The Correlativity Analysing Between COD and BOD for the Waste Water of the Sugar Refinery

Analysing the waste water of the suger refinery for BOD, it's always necessary for us to dilute the same water sample into several samples in different multiple, and then detect them one by one. But sometimes, the experiment would be failed, By analysing to determine the date of waste water of the thirteen suger refineies in this paper, the reclinear regress eguation has been set up between COD and BOD. According to this, we would get the estimation of BOD from COD, and exactly select the dilute multiple of the water sample, rising the experimental success.
