摘要
利用PCR-DGGE分析技术,对于化学生物絮凝处理工艺中悬浮填料塔的氨氧化细菌(AOB)群落进行了研究。主要考察了曝气强度和水力停留时间2个运行参数调整的情况下,系统AOB群落结构的变化。生物膜样品直接取自硝化填料塔,多维尺度(MDS)方法用于DGGE电泳图谱的分析,分析结果以二维图形向量的方式显示,结果表明,曝气强度和水力停留时间均对AOB群落有一定的影响,主要的AOB种类在运行过程中基本不变,系统对于运行条件具有良好的稳定性。
It was studied that ammonia-oxidizing bacteria(AOB) community in a nitrifying suspension tower for biochemical flocculation process,using PCR-DGGE technique.The change in systematic AOB community structure was examined under the regulation of aeration strength and hydraulic residence time(RHT).The biofilm samples were taken directly from a nitrifying filler tower.MDS method was used for the analysis of DGGE electrophoretogram,and the results were displayed by 2-D pattern.The results show that the aeration strength and RHT have a certain effect on AOB community.The main AOB strains remain unchanged in the process of running.
