摘要
对水中 BOD5与 CODCr的相关性进行了分析 ,以通过 CODCr的值快速推算出 BOD5的值。结果表明 ,废水 BOD5与CODCr数值之间线性关系显著。在生产稳定的情况下 ,只要测定出废水的 CODCr就可通过回归方程及置信区间预算出 BOD5。预算值与实测值相比较 ,平均相对误差 <5.85% ,经统计性检验两者无显著性差异。
The relation between BOD 5 and COD Cr was analyzed, so that BOD 5 data were quickly predicted from COD Cr data The results showed that their relation basically is linear When the operation of wastewater treatment unit is stable, as soon as COD Cr data is analyzed, through their regression equation BOD 5 predictive values were compared with its operation data at believable region The mean relative error of <5 85% are obtained, and predictive value is not obvious different from operative data by statistic examination
