Research on Electric Catalytic Oxidation Degradation of Methyl Orange Dyestuff Wastewater under the Condition of Different Single Factor

[目的]培养高活性的亚硝化生物膜，再将其作为接种微生物启动ANAMMOX反应器。[方法]试验通过监测进出水中NH4^＋-N和NO2--N的变化情况判定反应器工作环境是否由亚硝化为主逐步转变为以厌氧氨氧化为主，继而判定厌氧氨氧化反应器的启动是否完成。[结果]反应器在第185～201天运行稳定，亚硝氮与氨氯的平均去除比例分别为0．65和0．62，而厌氧状态下氨氮和亚硝氮以一定的比例被同时去除是厌氧氨氧化反应器成功运行的特征之一。[结论]亚硝化微生物作为ANAMMOX反应器的接种微生物是可行的。

[Objective] Nitrification biofilm in this experiment was aimed at training the high activity, which were treated as microbial inoculation starting ANAMMOX reactor. [Method] Changes of the experimental NH4＋-N and NO2-N in water by monitoring and judging reac- tor work environment was dominated by Nitrosomonas gradually shift to anaerobic ammonia oxidation, and then determined the start-up of anammox reactor was complete. [Result]The reactor in the 185-201 d ran stably, and nitrite nitrogen and ammonia nitrogen average re- moval rates were 0.65. and 0.62. Removal of ammonia nitrogen and nitrite nitrogen under condition of anaerodic in certain ratio was one of the characteristics of successful operation of anaerobic ammonia oxidation reactor. [Conclusion] The result permitted Minya nitrifying microorganisms as microbial inoculation the ANAMMOX reactor was feasible.
