Bitumen extraction from the Canadian Oil Sands generates large quantities of hydrocarbon contaminated wastewater, or Oil Sands Process Wastewater (OSPW). OSPW is usually stored in large tailings ponds indefinitely and not allowed to be discharged to surface waters. Cost effective solutions for reclaiming OSPW are being explored but have not been realized to date. The objective of the proposed university-industry collaboration are (i) to investigate the ability of treatment wetlands to reclaim OSPW in Canada and (ii) to support the application of treatment wetland for industry in Canada. The research involves (i) field studies of the removal of hydrocarbons and their associated aquatic toxicity from wastewater in a newly built and operational Kearl Treatment Wetland (TW) in Alberta and (ii) the development and testing of a contaminant fate and toxicity model that relates wetland treatment efficiency to operational and environmental conditions in Canada and regulatory requirements.The field data and modelling efforts generated in the study will support future development and design of TWs in Canada that are both effective in removing contaminants and safe for species inhabiting or visiting the wetland. This research project will allow industry to better understand the feasibility of treatment wetlands for OSPW reclamation in Canada. The results are expected to inform the oil sands industry on one potential solution to the OSPW challenge. The proposed research will take advantage of facilities, operating capacity and on-the-ground expertise of industry, and environmental chemistry, experimental design and mathematical modeling expertise from academia. Benefits to Canadian industry are enhanced OSPW treatment capacity and improved expertise in wetland treatment. Benefits to the University are to engage with industry on a key environmental and economic issue in Canada; to take advantage of industry capacity and expertise and to train students and other highly qualified personnel in green technology. Benefits to the engineering discipline include further development of environmental treatment science and technology.

从加拿大油砂中提取沥青会产生大量碳氢化合物污染的废水或油砂过程废水（OSPW）。 OSPW通常会无限期地存储在大尾矿池塘中，不允许将其排放到地表水域中。正在探索用于回收OSPW的经济有效解决方案，但迄今尚未意识到。拟议的大学 - 行业合作的目的是（i）调查湿地在加拿大收回OSPW和（ii）支持加拿大工业湿地的应用的能力。这项研究涉及（i）（i）对去除碳水化合物的去除及其相关的水生毒性的现场研究加拿大的TWS既可以有效地去除污染物，又可以安全地居住或参观湿地的物种。该研究项目将使行业能够更好地了解加拿大湿地治疗湿地的可行性。预计结果将为油砂行业提供有关OSPW挑战的一种潜在解决方案。拟议的研究将利用工业的设施，运营能力和现场专业知识，以及来自学术界的环境化学，实验设计和数学建模专业知识。加拿大工业的好处是增强的OSPW治疗能力和提高湿地治疗方面的专业知识。对大学的好处是在加拿大的关键环境和经济问题上与行业互动；利用行业能力和专业知识，并培训学生和其他高素质的绿色技术人员。工程学科的好处包括进一步发展环境治疗科学技术。
