摘要
探讨了影响废水中亚硝酸盐积累的三大主要因素:溶解氧、温度和pH。针对常温低氨氮城市污水,从理论上分析了以活性污泥法和生物膜法的形式进行亚硝化的启动方法和运行策略,为短程硝化/厌氧氨氧化工艺在城市污水处理中的应用提供了可借鉴的研究基础。
The three main factors, dissolved oxygen, temperature and pH, that influenced nitrite accumulation of sewage were studied. The startup method and operational strategy of nitrosofication with activate sludge and hiofilm were analyzed theoretically for the urban sewage of normal temperature and low ammonia nitrogen, and it provided valuable research base for the application of shortcut nitrification/ anaerobic ammonia-oxidizing in urban sewage treatment.
