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

成熟的被动和自然衰减渗滤液管理替代办法需要全面和综合的办法，以确保持续的渗滤液缓解。该项目旨在开发、测试和示范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的混合被动处理系统和随后的自然衰减区控制释放和处理城市垃圾填埋场渗滤液，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：(1)设计、建造和长期监测在温带气候条件下在梅里克垃圾填埋场处理渗滤液的最先进的中试规模的废热温度调节综合混合无源系统的设计、建造和长期监测；(2)通过中试规模的混合无源系统处理的渗滤液的毒性评估，并确定排放对地表接收器的潜在影响；(3)通过全面的水文地球化学研究和确定渗滤液羽流扩散潜力，确定渗滤液、地下水和地表水的相互作用，以控制渗滤液的排放，从而针对排放特征来加强接收器。这项研究涉及与北湾市、Aqua Treatment Technologies和Conestoga-Rovers&Associates的合作伙伴关系。北湾市将成为加拿大其他城市的示范设施，项目成果将使我们的支持组织能够将这种经济高效的综合混合被动处理方法的要素直接应用于其他市政和工业垃圾渗滤液应用。将至少培训3名研究生和3名本科生，提供有助于环境可持续发展部门研究和技术开发的专业知识。对于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的管理人员来说，开发和演示具有成本效益的渗滤液处理本地化创新解决方案具有巨大的经济潜力。

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.
