摘要
[目的]研究某采油管理区生活污水处理站出水样品中化学需氧量与浊度之间的关系,提出便捷、快速判断污水水质的方式,为该处理站运营人员提供管理依据.[方法]使用快速测定仪,对2023年8月份不同日期,在该采油管理区生活污水处理站出口处采取的16个水样的化学需氧量与浊度进行检测,并使用最小二乘法对检测数据进行整理、分析.[结果]结果表明,该采油管理区生活污水处理站出水水样中化学需氧量与浊度存在线性正相关关系,线性方程为y=0.247 1x-4.848 8,线性回归判定系数R2=0.931 5(即化学需氧量与浊度具有较高的相关性).[结论]可以通过简单易测的浊度来表征该采油管理区生活污水处理站出水中的化学需氧量.
Abstract
[Purposes]The relationship between chemical oxygen demand(COD)and turbidity in the efflu-ent of domestic sewage treatment station in an oil production management area was studied to judge the quality of sewage in a convenient and rapid way,so as to provide management basis for the operators of domestic sewage treatment station in the oil production management area.[Methods]16 water samples taken at the exit of domestic sewage treatment station in the oil production management area on different dates in August,2023 were tested and analyzed with a rapid analyzer,and the chemical oxygen demand and turbidity of each water sample were determined respectively.[Findings]The results showed that there was a linear positive correlation between chemical oxygen demand and turbidity in the discharge water of domestic sewage treatment station in the oil production management area,and the linear equa-tion was y=0.247 1x-4.848 8,which linear regression coefficient R2=0.931 5(namely chemical oxygen demand and turbidity have a high correlation).[Conclusions]The turbidity can be easily measured to characterize the chemical oxygen demand in the effluent of the domestic sewage treatment station in the oil production management area.
