强化脱氮Bardenpho工艺碳源投加位置及内回流比的确定

Determination of Carbon Source Addition Position and Internal Reflux Ratio in Bardenpho Process for Enhanced Denitrification

在分析传统四阶段Bardenpho脱氮工艺计算公式的基础上引入碳源不足系数H,通过修正后的公式对多参数进行了交叉迭代分析,根据来水碳源的情况,选择碳源的合理投加位置,以达到减少碳源投加量,减少混合液内回流比,从而减少运行成本。

Based on the calculation formula analysis of the traditional four-stage Bardenpho process for denitrification, the coefficient of insufficient carbon source H was introduced. The revised formulas were used to perform the iterative cross analysis of the parameters. According to the condition of the water carbon source, the reasonable addition position of carbon source was chosen in order to decrease the a- mount of carbon source addition and reduce the internal reflux ratio of the mixture, thus reducing the operating costs.
