Management of domestic wastewater is a pressing environmental problem in most rural communities in Canada, including First Nations communities. Typically, these communities collect municipal wastewater for transport to sewage lagoons, and the partially treated wastewater is discharged seasonally from these lagoons into surface waters. Rural communities are struggling to meet new Environment Canada regulations for wastewater effluent quality directed at protecting aquatic life in receiving waters. We propose to integrate ozone treatment with biological treatment to improve the overall performance of wastewater treatment processes. In bench scale tests and in pilot-scale studies conducted in two First Nations communities in Ontario, we will investigate whether ozone applied as a pre-treatment can improve wastewater treatment in sewage lagoons, and reduce impacts on aquatic organism in receiving waters. We will work with Aclarus Ozone Water Systems, a water treatment company based in Peterborough, ON that manufactures robust ozonation systems that can operate under extreme weather conditions. The Ontario First Nations Technical Services Corporation will collaborate on pilot-scale studies in the two First Nations communities. This work will also be supported by CREATE H2O, a program funded by the Natural Sciences and Research Council that is training water practitioners to work with First Nations communities to address water-related problems.

在加拿大的大多数农村社区，包括原住民社区，家庭废水管理是一个紧迫的环境问题。通常，这些社区收集城市废水，将其输送到污水泻湖，部分处理后的废水季节性地从这些泻湖排放到地表沃茨。农村社区正在努力满足加拿大环境部旨在保护接收沃茨水生生物的废水排放质量新规定。我们建议将臭氧处理与生物处理结合起来，以提高废水处理工艺的整体性能。在安大略两个原住民社区进行的实验室规模试验和中试规模研究中，我们将调查臭氧作为预处理是否可以改善污水泻湖的污水处理，并减少对接收沃茨水生生物的影响。我们将与Aclarus臭氧水系统公司合作，Aclarus臭氧水系统公司是一家位于彼得伯勒的水处理公司，该公司生产可在极端天气条件下运行的强大臭氧化系统。安大略第一民族技术服务公司将在两个第一民族社区合作进行试点研究。这项工作还将得到由自然科学和研究理事会资助的CREATE H2O方案的支持，该方案正在培训水从业人员与原住民社区合作解决与水有关的问题。
