Abstract
Methods to estimate nitrification rate, Kn, for river systems are proposed in this paper. Taking the Toujiang River in China as an example, a detailed comparison of the methods proposed in this study is presented. There is a good fit by using First‐Order, Two‐Station and the Least‐Squares method. A relationship between the measured and the theoretical nitrogenous oxygen demand (NOD) is developed and has been applied to estimate the influence of nitrification on oxygen balance for a river system without determining the NOD.
