摘　　要：介绍了前置反硝化SBR与连续流前置反硝化工艺相比在脱氮方面的优势。详细介绍了前置反硝化SBR工艺的设计方法——简化模型法,该法以活性污泥法动力学模型ASM1、ASM2和ASM3为理论基础,精简了动力学模型的参数数量,对SBR系统的碳源和NO3--N进行了核算,可以保证SBR最大限度地利用进水中的碳源进行高效脱氮。针对三种C/N值不同的废水,给出了前置反硝化SBR工艺具体的设计实例,并对设计结果进行了分析。The advantage of pre-denitrification SBR process in nitrogen removal over the continuous pre-denitrification process is introduced with the emphasis on a new design method called simplified model method. Based on the activated sludge models ASM1, ASM2 and ASM3, this method reduces the number of parameters for the kinetic models and calculates the carbon source and nitrate, which ensures that the carbon source in the influent can be fully used for denitrification. Three design examples are given with different C/N ratios of wastewater, and the design results are analyzed.
