Effects of Micro-Nanometer Aeration on Nitrogen Removal by Plant Floating-Beds

  • 摘要: 为探索微纳米曝气技术对再力花植物浮床脱氮的影响,研究了不同曝气方式〔微纳米曝气组、鼓风曝气组、无曝气浮床(对照组)〕的处理效果. 结果表明,与对照组相比,微纳米曝气组对TN和NH4+-N的去除率提高了13.35%和21.72%,而鼓风曝气组分别提高了5.64%和10.61%. 但微纳米曝气形成的富氧环境不利于NO3--N的去除,去除率低于鼓风曝气组和对照组浮床. 微纳米曝气对植物的生长有显著改善,试验结束时植物生物量增加了65.38%,而鼓风曝气组、对照组分别只增加了21.05%及63.93%. 植物吸收的TN也存在显著差异,微纳米曝气组最高,为90.60 mg,鼓风曝气组为54.84 mg,对照组为63.42 mg. 微纳米曝气比鼓风曝气具有更好的充氧效果,可显著改变植物根系微环境,有利于植物根系氨化细菌、硝化细菌的生长,但不利于反硝化细菌的生长.
