基于北京市2处人工湿地净化工程,采取系统内间歇回流方式,探讨水位调控措施对含氮污染物净化效果及微生物群落变化影响.结果 表明:水位调控措施有效地促进了对含氮污染物的去除,对TN、NH3-N的去除率分别提升19.23％～28.09％和29.23％～40.64％;与传统运行方式下去除效果达到显著差异性水平(P＜0.05).水位调控湿地单元内微生物群落丰富度指数Cha01(3022.4522,3349.2942)高于传统湿地;变形菌Proteobacteria丰度高达63％～ 70％,为门水平优势种;属水平优势种较传统运行条件有明显差异,且群落结构更具一致性,本研究旨在分析水位调控措施对湿地系统脱氮性能强化程度,以及微生物群落结构的响应关系,为人工湿地效率提升以及应用推广提供技术支撑.
