摘要
本论文采用短程硝化反硝化倒置A~2/O工艺对生活污水脱氮效果进行研究,首先通过倒置A~2/O工艺与常规A~2/O工艺的对比实验,确定倒置A~2/O工艺在保证COD去除率的前提下脱氮的优越性。然后对生物脱氮的相关机理进行了探讨,并对影响系统脱氮效果的各种因素(诸如温度、溶解氧浓度、污泥回流比、C/N比、pH值等)以及主要的运行机理进行了较详细的分析研究,试验结果表明,实现短程硝化反硝化最佳条件是:温度18～25℃,溶解氧DO=2mg/L,pH值在6.5～7.5范围内。短程硝化反硝化倒置A~2/O工艺最佳工艺参数为:C/N为3.48,污泥回流比为200%。
The short-cut nitrification and denitrification in the inverted A~2/O process was used for the analysis on denitrogenation characteristic of the sewage in the paper.The experiments testify that inverted A~2/O process is superior of denitrogenation to traditional A~2/O process in the premise of ensuring removal of COD.The paper discuss mechanism of nitrogen removal and study the various kinds of influence factors(such as temperature, dissolved oxygen concentration, sludge reflux ratio,C/N,PH,etc.),and detailed study the main operation mechanism.Optimal operating parameters are achieved in the short-cut nitrification and denitrification was:T=18～25℃,DO=2mg/L,pH=6.5～7.5;and in the short-cut nitrification and denitrification in the inverted A~2/O process was: C/N=3.48,R=200%。
