摘　　要：研究了低浓度阿特拉津冲击对A/O工艺运行稳定性的影响,并探索了通过优化工艺参数强化处理低浓度阿特拉津的可行性。结果表明,和碳氧化活性相比,阿特拉津对活性污泥系统硝化活性的抑制作用更强,同时其代谢产生的氨氮又增加了系统负荷,最终导致氨氮去除率维持在较低水平上。采用调整A/O工艺参数的方式,可实现低浓度阿拉特津的强化处理,最优运行参数为硝化液回流比=200%,缺氧区/好氧区停留时间比=1∶3。在该运行工况下,目标污染物被高效去除,系统运行稳定。The effect of low concentration atrazine impact on the running stability of A/O process was discussed in this paper.And the feasibility of enhancing the treatment of low concentration atrazine through optimizing operation parameters was also analyzed.Results showed that,compared with the activity of carbon oxidation,atrazine showed much more strong inhibition to nitrification activity of actived sludge.Meanwhile,ammonia nitrogen produced by the metabolites of atrazine also increased system loading which leads to a low level of ammonia nitrogen removal rate.Treatment of low concentration atrazine could be enhanced through optimizing A/O operation parameters.The optimized reflux ration of nitrate solution was 200%,and volumetric ratio of anaerobic section/aerobic section was 1∶3.Under this running condition,the pollutants were efficiently removed,and the system can steadily run.
