HETEROTROPHIC NITRIFICATION-AEROBIC DENITRIFICATION CHARACTERISTICS OF ALCALIGENES FAECALIS WT14 AND ITS POTENTIAL APPLICATION IN AMMONIA-RICH WASTEWATER

  • 摘要: 异养硝化-好氧反硝化(HN-AD)菌具有同步硝化反硝化的特性,在污水生物处理方面引起了广泛关注。为探究HN-AD菌在处理高氨废水方面的应用潜力,以前期从人工湿地底泥基质中分离出的HN-AD菌Alcaligenes faecalis WT14为研究对象,在好氧条件下研究了该菌株的脱氮特性,并对其高氨废水去除潜力和环境因子交互作用对其脱氮效率影响方面进行了评估。实验结果表明,WT14表现出高效的HN-AD性能,能够同步脱氮除碳,在好氧条件下能够去除98.9%的NO3--N和92.7%的TOC,且不含NO2--N的积累。同时,在游离氨(FA)浓度为1084.6 mg/L的高NH4+-N(2000 mg/L)废水中,NH4+-N去除率约为43%,脱氮速率可达55.9 mg/(L·h),且无NO3--N的积累。响应面结果表明:其最佳脱氮条件为20.6 ℃, 113.5 r/min, C/N=10.8,pH=8.4。总体而言,菌株WT14具有高效处理高氨废水的应用潜力。
