摘要
针对炼油废水A/O工艺氨氮去除率低的问题,运用生物脱氮原理对其影响因素进行了分析。论述废水强化预处理除油的重要性,提出应根据废水水质选择合理的硝化工艺,并提出了改进现有工艺的措施。
In view of the low ammonia nitrogen removal efficiency of when using A/O process to treat refinery wastewater, biological nitrification and denitrification theory is utilized to analyze relevant influencing factors.Importance of unoiling as pretreatment in the whole process is discussed.It is proposed that reasonable nitrification process should be selected on the basis of wastewater characteristics.Improvement on the existing technique is also presented in the paper.
