进水基质对厌氧氨氧化反应器稳定性能的影响

利用ASBR试验装置接种城市污泥成功启动反应器后，研究其厌氧氨氧化工艺对进水基质抗冲击能力的影响。结果表明：进水NO2^--N的降低对反应器去除NH4^＋-N和NO2^--N影响不大，对TN影响较大。当进水NO2^--N与NH4^＋-N质量比为0．3时，TN去除率低于50％。当保持进水基质比值不变，考察高负荷稳定运行时降低NH4^＋-N负荷对反应器性能的冲击，在进水NH4^＋-N浓度由高逐渐降低过程中，NH4^＋-N、NO2^--N去除率高达100％，而NO3^--N生成量逐渐增加。当进水NH4^＋-N在10mg／L时．TN去除率降至6．5％。向低氨（NH4^＋-N浓度〈10mg／L）废水中加...

Summary:利用ASBR试验装置接种城市污泥成功启动反应器后，研究其厌氧氨氧化工艺对进水基质抗冲击能力的影响。结果表明：进水NO2^--N的降低对反应器去除NH4^＋-N和NO2^--N影响不大，对TN影响较大。当进水NO2^--N与NH4^＋-N质量比为0．3时，TN去除率低于50％。当保持进水基质比值不变，考察高负荷稳定运行时降低NH4^＋-N负荷对反应器性能的冲击，在进水NH4^＋-N浓度由高逐渐降低过程中，NH4^＋-N、NO2^--N去除率高达100％，而NO3^--N生成量逐渐增加。当进水NH4^＋-N在10mg／L时．TN去除率降至6．5％。向低氨（NH4^＋-N浓度〈10mg／L）废水中加入葡萄糖后，TN去除率立即上升，当进水溶解性有机碳（DOC）为90mg／L时，TN去除率达到90％，说明反应器可以良好的处理模拟养殖废水。

The start-up of ANAMMOX process in ASBR reactor seeding with activated sludge from a municipal sewage treatment plant was investigated. The study had tested the performance of ASBR ANAMMOX reactor by the ratio chang of influent matrix. The results showed that there had no effect on removing NH4＋-N and NO2--N while having great influence on TN by reducing influent concentration of NO2--N. NH4＋-N was completely removed. When the ratio of influent concentration of NO2 -N/NH4＋-N reduced to 0.3, the removal rate of TN was below 50%.The study also tested the performance of ASBR ANAMMOX reactor by reducing the loading of reactor as maintaining the concentration of influent nitrite and ammonia. Results showed that removal efficiency of NO2--N and NH4＋-N were stable as high as 100% in the process of int2uent NH4＋-N decreased gradually, but the produced nitrate increased gradually. When influent NH4~-N reduced to lOmg/L, the removal rate of TN reduced to 6.5%.The removal rate of TN immediately rose after addin
