为探究引入植物对生物净化槽处理黑臭河水的影响及机理,结合水质理化指标的动态变化,采用了ERIC-PCR指纹图谱技术来分析生物净化槽内的微生物群落结构在植物不同生长阶段的变化特征,比较植物与填料不同工艺组合对微生物群落结构的影响.结果发现:引种梭鱼草(Pontederia cordata L)的生物净化槽对主要污染物COD_(cr),NH_3-N和TP的去除率分别提高了19.8%～69.4%,18.2%～68%和23.9%～77.2%;微生物群落结构随植物不同生长发育阶段而变化,分蘖期优势菌群的种类和数量最多,同期净化效果也最好;从三种工艺的运行效果来看,植物+组合填料搭配最合适.

The effects and mechanisms of pioneer plant on the purification of malodorous river water in phytoremediation tank were evaluated. According to the relationship between the major pollutants removal effect and the microbial community structure, which was investigated by ERIC-PCR fingerprinting, it was found that Pontederia cordata L had obvious effect on the pollutant removal, the removal efficiencies of COD_(cr), NH_3-N and TP being 19. 8%~69.4%,18.2%~68% and 23.9%~77. 2% higher than those of control group. Meanwhile, the three tanks planted with Pontederia cordata L had more abundant microbial species than those without hydrophytes. It also remarkably indicated that the diversity of the predominant bacteria at tille-ring stage was much greater than that at other stages and the combination of plant and compounding medium was the best technologic model in three different types.
