    摘要:

    为拓展新型生物脱氮技术的应用领域,研究了生产性短程硝化-厌氧氨氧化装置处理制药废水的启动性能。制药废水氨氮浓度为 (430.40±55.43) mg/L时,氨氮去除率达 (81.75±9.10)%,实现了短程硝化-厌氧氨氧化工艺对制药废水的生物脱氮。制药废水短程硝化系统的启动时间约为74 d,亚硝氮积累率达 (52.11±9.13)%,证明了结合模拟废水和实际废水的“两步法”模式对短程硝化系统启动的适用性。制药废水厌氧氨氧化系统的启动时间约为145 d,最大容积氮去除速率达6.35 kg N/(m3·d),容积效能为传统硝化反硝化工艺的数十倍,证明了结合菌种自繁和菌种流加的模式对厌氧氨氧化系统启动的适用性。

    Abstract:

    In order to broaden the application area of the new nitrogen removal technology, A full-scale system for short-cut nitrification and anaerobic ammonium oxidation (Anammox) was investigated in the nitrogen removal from a strong-ammonium pharmaceutical wastewater. When the influent ammonium concentration was (430.40±55.43) mg/L, ammonia removal efficiency was (81.75±9.10) %. The results showed that the short-cut nitrification and Anammox system could successfully remove nitrogen from the pharmaceutical wastewater. The start-up of short-cut nitrification system took about 74 d and the nitrite accumulation efficiency was (52.11±9.13) %, the two-step mode using synthetic wastewater and actual wastewater was suitable for the start-up of short-cut nitrification system. The start-up of Anammox system took about 145 d and the maximum volumetric nitrogen removal rate was 6.35 kgN/(m3·d), which were dozens of times higher than those for the conventional nitrification–denitrification process. The strategy achieving Anammox sludge by self-growth and biocatalyst addition was suitable for the start-up of Anammox system.
