Wetland treatment of oil sands process water

从加拿大油砂中提取沥青会产生大量的烃污染废水，或油砂工艺废水（OSPW）。OSPW通常无限期地储存在大型尾矿池中，不允许排放到地表沃茨。回收OSPW的成本效益解决方案正在探索中，但迄今尚未实现。拟议的大学和工业合作的目标是（i）调查处理湿地回收加拿大OSPW的能力，以及（ii）支持加拿大工业应用处理湿地。该研究包括：（i）在阿尔伯塔新建和运行的KALCOST处理湿地（TW）中，对废水中碳氢化合物及其相关水生毒性的去除进行实地研究;（ii）污染物归宿和毒性模型的开发和测试，该模型将湿地处理效率与加拿大的操作和环境条件以及法规要求联系起来。将支持未来的发展和设计的TW在加拿大，既有效地消除污染物和安全的物种栖息或访问湿地。该研究项目将使工业界更好地了解加拿大OSPW填海处理湿地的可行性。预计结果将告知油砂行业一个潜在的解决方案OSPW的挑战。拟议的研究将利用设施，运营能力和工业的实地专业知识，以及学术界的环境化学，实验设计和数学建模专业知识。对加拿大工业的好处是提高了OSPW的处理能力和改进了湿地处理方面的专门知识。对大学的好处是在加拿大的一个关键的环境和经济问题上与行业接触;利用行业的能力和专业知识，并培训学生和其他高素质的人员在绿色技术。对工程学科的好处包括环境处理科学和技术的进一步发展。

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.**********
