Development of a novel ozonation system at pilot scale for wastewater disinfection and removal of contaminants of emerging concern

公众和科学界对与新出现的感兴趣的污染物相关的环境和公共健康问题越来越感兴趣。加拿大的许多废水处理厂正计划投资于处理基础设施的升级，以应对旨在改善废水质量和/或保护用于供应饮用水的水源的更严格的法规。这一拟议的项目将确保对深度处理技术的投资具有消除新出现问题的污染物(CECs)的额外好处；从而保护环境和提供安全可靠的饮用水来源。这个合作研发项目的目标是提高使用臭氧对不同类型的废水进行消毒的潜力，并在排放到接收溪流之前有效地从废水中去除CECs。项目的另一个目标是向加拿大市政当局的水处理从业人员提供必要的信息，以便在污水处理厂安装更多处理技术的早期作出科学合理的决定。该行业、麦吉尔大学和特伦特大学之间的合作项目将建立在我们在臭氧处理、废水处理、CECs去除和转化以及毒性测试方面的集体专业知识的基础上。这项研究将提供a)更好地了解污水处理厂污水深度处理中CECs的去除和转化；b)用于废水处理的先进臭氧技术；c)关于实施先进氧化技术以减少CECs排放和影响的建议；d)臭氧气体的新市场；以及e)具有跨学科背景的HQP培训。我们的工业合作伙伴将获得有价值的信息，使他们能够进一步开发和测试技术，以达到有针对性的消毒和CECs去除水平。该项目将使他们能够在日益增长的兴趣领域占据领先地位。确保安全可靠的供水系统将使加拿大社会受益，从而减少长期明显的健康和环境问题。

To The public and the scientific community are increasingly interested in the environmental and public-health concerns associated with contaminants of emerging interest. Many wastewater treatment plants in Canada are planning to invest in upgrades to treatment infrastructure to respond to more stringent regulations aimed at improving wastewater quality and/or to protect the sources of water that are used to supply drinking water. This proposed project will ensure that investments in advanced treatment technologies have the added benefit of removing contaminants of emerging concerns (CECs); thereby, protecting the environment and providing safe and secure sources of drinking water. The objective of this collaborative R&D project is to improve the potential for using ozonation to disinfect different types of wastewater and to efficiently remove CECs from wastewater before discharge to receiving streams. Another project objective is to provide water treatment practitioners in Canadian municipalities with the information required to make scientifically sound decisions early in the process of installing additional treatment technologies in WWTPs. The collaborative project between the industry, McGill University and Trent University will build upon our collective expertise in ozonation, wastewater treatment, CECs removal and transformation and toxicity testing. This research will provide a) an improved understanding of removal and transformation of CECs in advanced treatment of WWTP effluents; b) advanced ozonation technologies for wastewater treatment; c) recommendations on ways to implement advanced oxidation technologies to mitigate the release and impacts of CECs; d) a new market for ozone gas, and e) training of HQP with a trans-disciplinary background. Our industrial partners will obtain valuable information that will allow them to further develop and test the technology in order to meet targeted disinfection and CECs removal levels. This project will allow them to take a leading position in that area of growing interest. Ensuring safe and secure water systems will benefit Canadian society by subsequent reduction of long term obvious health and environmental issues.
