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浸漏液管理替代办法需要采取全面和综合的办法，以确保持续减缓浸漏液。该项目旨在以试点方式开发、测试和演示一种最先进的综合混合被动处理技术，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，对城市垃圾填埋场渗滤液进行控制排放和处理，并有助于改善自然枯竭的接收环境中新建立的鱼类栖息地。具体的研究目标包括：（一）设计、建造和长期监测一个最先进的中试规模的废热温度调节综合混合被动系统，在温带气候条件下处理梅里克垃圾填埋场的渗滤液;（二）对通过中试规模的混合被动系统处理的渗滤液进行毒性评估，并确定释放对地表接收器的潜在影响;及（iii）透过全面的水文地球化学研究，确定渗滤液、地下水及地面水之间的相互作用，以及确定渗滤液羽流扩散潜力，以便针对排放特性，控制经处理的渗滤液的排放，以加强接收器。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城市和工业垃圾填埋场渗滤液应用。至少有3名研究生和3名本科生将接受培训，提供有利于环境可持续性部门研究和技术发展的专业知识。开发和示范成本效益高的自然化创新的沥滤液处理办法，对加拿大较小的城市、加拿大环境咨询工程师和垃圾填埋沥滤液系统管理人员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.
