摘要
地表水五日生化需氧量（ＢＯＤ５）的测试需要五天时间，分析周期较长。本文建立了ＢＯＤ５与高锰酸盐指数（ＣＯＤＭｎ）、ＢＯＤ５与溶解氧（ＤＯ）之间的直线回归方程，通过测定地表水的ＣＯＤＭｎ和ＤＯ可分别对地表水的ＢＯＤ５实现快速预测预报。现场使用溶解氧测定仪检测ＤＯ，可立即预报地表水的ＢＯＤ５。
Examine five day biochemical oxygen demand (BOD 5)of surface water needs 5 day time,analysis period more lenger In this paper,established straight line regression equation between BOD 5 and permanganate index(COD Mn )or BOD 5 and dissolved oxygen(DO) By determine COD Mn and DO for surface water,may respectively relized rapid calculate forecast for BOD 5 of surface water Useing dissolved oxygen meter examin DO at scene,may immediately forecast BOD 5 of surface water
