| 摘 要： | 以沈阳某污水处理厂的进水水质为例,用SPSS软件对COD和BOD进行回归分析。结果表明,COD和BOD之间具有线性关系,其一元线性回归方程为COD=35.76+2.26*BOD。利用该回归方程测算BOD,对预测值和实际值进行t检验,发现两者之间不存在显著性差异,从而表明利用回归方程测算BOD方便快速,有助于生产运行管理。

| Abstract: | Taking the influent water quality of a wastewater treatment plant in Shenyang as example, this paper analyzed the relationship between COD values and BOD values by SPSS software. The results indicate that values of COD and BOD are in linear relation. The linear regression equation is COD=35.76+ 2.26BOD. Compared the BOD value estimated by regression equation and the actual value with t test, there is no significant difference. So, using regression equation to estimate BOD value is convenient and helpful for management. |
