| 摘 要： | 某污水处理厂AAO工艺出水存在着pH值偏低的问题。通过对比历史数据和缺氧反硝化试验，研究了以进厂污水作为碳源的反硝化脱氮的能力及碳氮比对脱氮的影响，并通过碱度平衡核算，分析了硝化和反硝化段的情况，查找出了出水碱度不足pH偏酸的原因，提出了快捷、行之有效的控制方案。

| Abstract: | This paper analyzes the anoxic/anaerobic/aerobic process(AAO) technological process with acid pH Value of effluent.By comparing recorded data and anoxic de-nitrification test,it studies the de-nitrification capability of sewage as carbon source,as well as how the carbon and nitrogen affect the de-nitrification capability.Through assessing the alkalinity balance accounting,the situation of nitrification and de-nitrification was analyzed,to figure out why the pH Value is to be acid.Finally,practicable schemes... |
