- Title:
- Study on the Community Distribution of Periphytic Microorganisms at Sewage Outlet of a WWTP
- 摘要:
- 为了考察市政尾水补给径流对水生态的影响,对排污口着生型微生物进行高通量测序,考察了微生物群落与尾水水质间的响应关系。结果表明,在尾水平均COD、NH4+-N和TP为地表水Ⅳ类水质时,排口富集黄杆菌、不动杆菌、伯克霍尔德菌等致病菌,以及氨氧化菌(Nitrosomonas)、反硝化菌(Lysobacter)、聚磷菌(Enterobacte)等活性污泥中常见微生物。尾水平均COD、TN与聚磷菌丰度呈负相关(相关系数分别为-0.931和-0.909),TN与反硝化除磷菌(Xanthomonadaceae)丰度呈正相关(相关系数为0.964)。排口附近不利于富集脱氯单胞菌(Dechloromonas)等反硝化菌,受纳水体中的NO3--N难以靠尾水中的微生物降解。
- Abstract:
- In order to investigate the impact of municipal tail water recharged to runoff on aquatic ecology, high-throughput sequencing was tested on the periphytic microorganisms at sewage outlet, and the relationship between microbial community and effluent quality was analyzed. The results showed when the average effluent COD, NH4+-N and TP reached level Ⅳ standard for surface water, the outlet was enriched with pathogenic bacteria such as Flavobacterium, Acinetobacter, Burkholderia and common bacteria in activated sludge such as ammonia oxidizing bacteria Nitrosomonas, denitrifying bacteria Lysobacter, phosphorus accumulating bacteria Enterobacte. The average effluent COD and TN were negative correlated with Enterobacter abundance (r were -0.931 and -0.909 respectively), and the average effluent TN was positively correlated with the abundance of Xanthomonadaceae (r was 0.964). The vicinity of outlet is not conducive to accumulate denitrifying bacteria such as Dechloromonas, thus it is difficult to reduce the NO3--N in the receiving water by microorganisms in the tail water.
