不同碳源驯化活性污泥后其生物多样性的差异及对反硝化的影响的研究

Study on the Differences of Biodiversity and its Infects on Denitrification After Acclimating activated sludge With Different Carbon Sources.

文章分别向东北某污水处理厂2个完全独立的生物反应器中投放乙酸钠和麦可碳2000来驯化活性污泥,之后对污泥样品依次进行DNA提取、PCR扩增后再进行16S rRNA高通量测序分析,以探究经过这两种不同碳源驯化后活性污泥的生物多样性和微生物群落结构的差异以及其对总氮去除效果的影响,以期为污水处理厂选择合适的碳源提供理论参考。

The paper added sodium acetate and Michael Carbon 2000 to two completely independent bioreactors of a sewage treatment plant in Northeast China to domesticate activated sludge.DNA extraction and PCR amplification were performed on the sludge samples,followed by high-throughput 16S rRNA sequencing analysis.The paper explores the differences in biodiversity and microbial community structure between two carbon sources domesticated activated sludge,as well as their impact on total nitrogen removal efficiency,in order to provide theoretical reference for sewage treatment plants to choose carbon sources.
