摘要
采用回归分析,对金陵石化公司石油化工废水BOD5与CODcr的相关性进行研究,以快速预报废水BOD5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,只需测定废水CODcr,就可通过回归方程及置信区间预报BOD5,预测值与实测值比较,干均相对误差<12%,经统计检验,两者无显著性差异。
The correlation between (Biochemical Oxygen Demand)BOD and(Chemical Oxygen Demand) COD of petrochemical wastewater was studied by regression analysis in Jiming Petrochemical Corporation in order to predict BOD rapidly.As a result,the correlation between BOD and COD is significant linear. If COD was detemined, BOD can be predicted by regression equation and its confidence interval under stable water quality. Average relative error between predicted BOD and determined BOD is less than 12%. There ie no significant difference between two values by statistical test.
