  • 摘要: 通过小试实验考察了同步半硝化-厌氧氨氧化-反硝化(SNAD)系统启动和稳定化运行的条件。结果显示,通过控制温度、pH、DO、曝气方式以及碱度与进水氨氮的比值,采用人工富集厌氧氨氧化细菌的方法,成功启动了SNAD系统,并且实现了稳定化运行。氨氮和总氮的去除率均可达到90%以上,平均出水硝酸盐和进水总氮的比例可控制在11%以内。另外,在启动过程中还发现,菌体自溶贡献了大部分化学耗氧量(COD),但随着系统的稳定,菌体自溶现象趋于减小。
    Abstract: In this study, conditions of the start-up and stable operation of the simultaneous partial nitritation-anammoxdenitrification (SNAD) system were investigated by a lab-scale experiment. The results showed that the SNAD system was successfully started and went into a stable state by adjustment of the operation conditions including temperature, pH, dissolved oxygen (DO), aeration mode and the ratio of alkalinity to ammonia of the influent and by application of anammox bioaugmentation. The removal rate of ammonia and total nitrogen (TN) was over 90% and the mean ratio of effluent nitrate to influent TN was within 11%. In addition, bacterial autolysis contributed to the most of chemical oxygen demand (COD) in the start-up stage of the system but tended to decrease with the stability of the system.
