Removal of biologically active micropollutants from wastewater using advanced water treatment technologies

饮用水和废水处理技术传统上侧重于控制营养物质和病原体。然而，人们对开发专门从水中去除污染物的技术越来越感兴趣；特别是在世界上水资源稀缺和将家庭和工业废水回收用于其他用途的地区。该项目的重点是确定涉及在过氧化氢存在下用紫外光(UV)氧化的水处理技术是否有效地去除优先污染物，如来自家庭和工业来源的药品和内分泌干扰物质。我们还将确定在这些氧化处理过程中会形成哪些副产品。此外，我们将评估氧化处理对水中生物活性(例如雌激素活性)的去除作用。这项工作将有助于理解水中污染物通过光氧化降解的速率和机理。该项目将作为特伦特大学水质中心和安大略省伦敦市特洛伊技术公司之间的合作项目。这项研究的结果将提高特洛伊技术公司等加拿大公司开发和销售可应用于饮用水和废水处理的技术的能力。

Technologies for the treatment of drinking water and wastewater have traditionally focused on controlling nutrients and pathogens. However, there is increasing interest in developing technologies that specifically remove contaminants from water; especially in areas of the world where water is scarce and there is recycling of domestic and industrial wastewater for other applications. The focus of this project is to determine whether water treatment technologies that involve oxidation with ultraviolet (UV) light in the presence of hydrogen peroxide are effective in removing priority contaminants such as pharmaceuticals and endocrine disrupting substances of domestic and industrial origin. We will also determine what byproducts are formed during these oxidative treatment processes. In addition, we will evaluate the removal of biological activity (e.g. estrogenicity)from water as a result of oxidative treatment. This work will contribute to an understanding of the rates and mechanisms by which contaminants in water are degraded through photo-oxidation. The project will be conducted as a collaborative venture between the Water Quality Centre at Trent University and Trojan Technologies Inc. of London, Ontario. The results of this research will enhance the capacity of Canadian companies, such as Trojan Technologies to develop and market technologies that have applications for the treatment of drinking water and wastewater.
