摘要:为了对比移动床生物膜反应器(MBBR)与纤维球填料反应器在处理无机氨氮废水中的硝化性能差异,探究填料特性对硝化细菌富集能力及系统稳定性的影响,为优化生物脱氮工艺提供理论依据。实验采用相同条件(原水NH_(4)^(+)-N50 mg^(/)L、水力停留时间15 h),通过监测氨氮去除效果、亚硝酸盐积累及硝化活性等,评估两个系统的性能。结果表明,纤维球填料因其结构和高比表面积,更利于硝化细菌富集,氨氮平均去除率达97.6%,硝化过程更为彻底;而MBBR填料的生物膜附着性能较差,氨氮去除率为84.8%,亚硝酸盐积累率24.73%。此外,对NH_(4)^(+)-N和NO_(2)^(-)-N浓度变化进行方差分析的结果也证实了纤维球反应器运行更为稳定。该研究为低浓度无机氨氮废水处理中纤维球填料的优先选择提供了实验依据。
This study compares the nitrification performance of Moving Bed Biofilm Reactors(MBBR)and fiber-ball packing reactors in treating inorganic ammonia nitrogen wastewater.It aims to investigate the impact of packing characteristics on the enrichment capacity of nitrifying bacteria and system stability,thereby providing a theoretical basis for optimizing biological nitrogen removal processes.Under identical conditions(influent NH4+?N concentration of 50 mg/L,hydraulic retention time 15 h),the performance of the two systems was evaluated by monitoring ammonia nitrogen removal efficiency,nitrite accumulation,and nitrification activity.The results demonstrated that the fiber-ball packing,due to its structure and high specific surface area,was more conducive to the enrichment of nitrifying bacteria,achieving an average ammonia nitrogen removal rate of 97.6%and a more thorough nitrification process.In contrast,the MBBR packing exhibited poorer biofilm attachment performance,with an ammonia nitrogen removal rate of 84.8%and a nitrite accumulation rate of 24.73%.Furthermore,variance analysis of NH4+?N and NO2-?N concentration changes also confirmed that the fiber-ball packing reactor operates more stably.These findings provide experimental evidence for the preferential selection of fiber-ball packing in the treatment of low-concentration inorganic ammonia nitrogen wastewater.
