摘　　要：针对河北某污水处理厂冬季氨氮去除率大幅降低问题,分析了影响硝化性能的主要因素。结果表明,进水温度持续偏低和期间进水氨氮负荷冲击是造成生物池硝化性能异常的主要原因。采用低温硝化菌剂作为应急处理措施,实际效果显示,在生物池应急投加硝化菌剂,能够快速恢复生物池的硝化性能,可以作为保障污水处理厂安全稳定生产的有效应急处理措施之一。Aiming at the large decrease of ammonia nitrogen removal rate in a sewage treatment plant in Hebei in winter,the main factors affecting nitrification performance were analyzed.The results showed that the low influent temperature and the impact of influent ammonia nitrogen load were the main reasons for the abnormal nitrification performance of biological tank.Using low-temperature nitrifying agent as an emergency treatment measure,the actual effect shows that the emergency addition of nitrifying agent in the biological tank can quickly restore the nitrification performance of the biological tank,and can be used as one of the effective emergency treatment measures to ensure the safe and stable production of sewage treatment plant.
