An Integrated Hybrid Passive Landfill Leachate Treatment System to Preserve Fish Habitat - Cold Temperature & Pilot-Scale Study

完善的被动和自然衰减渗滤液管理备选办法需要全面和综合的办法，以确保持续减少渗滤液。该项目旨在在中试规模上开发、测试和展示一种最先进的综合混合被动处理技术，该技术将允许通过废热温度调节混合被动处理系统和随后的自然衰减区控制城市垃圾填埋场渗滤液的释放和处理，并有助于在自然枯竭的接收环境中加强新建立的鱼类栖息地。具体研究目标包括：(i)设计、建造和长期监测最先进的中试规模废热温度调节综合混合被动系统，在温和气候条件下处理梅里克垃圾填埋场的渗滤液；（ii）评估经中试混合被动系统处理的渗滤液的毒性，并确定其释放对地面接收设施的潜在影响；（iii）通过全面的水文地球化学研究来表征渗滤液、地下水和地表水的相互作用，并确定渗滤液羽散势，以控制处理后的渗滤液的释放，目标是排放特性，以增强接收者。这项研究涉及与北湾市、AQUA处理技术和Conestoga-Rovers & Associates的合作。北湾市将成为加拿大其他城市的示范设施，项目结果将使我们的支持组织能够直接将这种具有成本效益的综合混合被动处理方法的要素应用于其他市政和工业垃圾填埋场渗滤液的应用。至少有3名研究生和3名本科生将接受培训，为环境可持续性领域的研究和技术发展提供专业知识。开发和示范具有成本效益的自然化渗滤液处理创新解决方案对加拿大较小的市政当局、加拿大环境咨询工程师和垃圾填埋场渗滤液系统管理人员具有重大的经济潜力。

Well-developed passive and natural attenuation leachate management alternatives require comprehensive and integrated approaches to ensure sustained leachate mitigation. This project aims to develop, test and demonstrate, on a pilot-scale, a state-of-the-art integrated hybrid passive treatment technology that will allow for the controlled release and treatment of municipal landfill leachate through a waste heat temperature- regulated hybrid passive treatment system and subsequent natural attenuation zone, and contribute to the enhancement of a newly established fish habitat in a naturally depleted receiving environment. Specific research objectives include: (i) design, construction and long-term monitoring of a state-of-the-art pilot-scale waste-heat temperature-regulated integrated hybrid passive system treating leachate at the Merrick Landfill under temperate climatic conditions; (ii) toxicity assessment of leachate treated through the pilot-scale hybrid passive system and determination of potential impact of release on surface receivers; and, (iii) characterization of leachate, groundwater and surface water interactions through a comprehensive hydrogeochemical study and determination of leachate plume dispersion potential for the controlled release of treated leachate targeting discharge characteristics to enhance receivers. This research involves partnerships with the City of North Bay, AQUA Treatment Technologies and Conestoga-Rovers & Associates. The City of North Bay will become a demonstration facility for other Canadian municipalities and project findings will allow our supporting organizations to directly apply elements of this cost-effective integrated hybrid passive treatment approach to other municipal and industrial landfill leachate applications. At least 3 graduate and 3 undergraduate students will be trained, providing an expertise that will benefit research and technical development in the environmental sustainability sector. The development and demonstration of cost-effective naturalized innovative solutions for leachate treatment has significant economic potential for smaller Canadian municipalities, Canadian environmental consulting engineers and managers of landfill leachate systems.
