五日生化需氧量的两种快速测定方法

五日生化需氧量（BOD5）是水质监测的一个重要参数，但其经典测定方法繁琐、耗时、技术要求高，不能及时反映在水体受污染的程度，对工业废水处理的意义不大。本文主要介绍和验证了两种快速测定BOD5的方法，即增温法和相关估算法。通过实验证实了这两种方法具有周期短，操作简单等特点，对工业废水处理，污染预报等实际应用有一定的指导意义。

Two Rapid Ana1ysis Methods of BOD5

Biochemical oxygen demand of 5 days (BOD 5) was a very important parameter of monitoring ofwater quality. The classical method presented some shortcomings,such as complexity, long period, requirementof high technology and not promptly reflecting the pollution levels of water body, so it was of no significance fortreatment of industrial waste water. In this paper, two rapid methods for determination of BODs, raising incubation temperature and correlative estimation method, were introduced and their advantages, such as short period and simplicity of operation were verified by experiments. Modification of classical method was of certain instructive significance for the practical application to treatment of industrial waste water and forecast of pollutionlevels of water body.
