Bacterial communities and treatment of municipal wastewater in arctic waste stabilization ponds

The objective of the present study was to investigate the size, composition, diversity, and putative function of bacterial communities associated with treatment of municipal wastewater in passive waste stabilization ponds (WSP) operated in the Arctic. Information about the microbiology of these systems can help in optimizing the treatment systems in remote cold-climate areas. We conducted the fieldwork for this study over three years (2012-2014) in the two remote communities in Nunavut, Canada, where one-cell and two-cell WSP systems are used to provide primary treatment.

本研究旨在探究北极地区运行的被动式废物稳定塘（Waste Stabilization Ponds, WSP）处理市政污水过程中相关细菌群落的丰度、组成、多样性及推定功能。此类系统的微生物学相关信息，可助力优化偏远寒冷气候区域的污水处理系统。本研究于2012至2014年的三年间，在加拿大努纳武特地区的两个偏远社区开展实地工作，该区域采用单池与双池式WSP系统进行一级处理。
