After a precious metal mine closes, the mining company is responsible for the site's long-term environmental management, which includes treatment of contaminated waters. Most Canadian mines use a traditional wastewater treatment plant to treat contaminated waters. The treatment plants are costly to run, energy-intensive, and are not environmentally sustainable. The primary objective of this research study is to complete the detailed design of a natural, long-term, low-energy wastewater treatment method tailored to treat a specific former Ontario gold mine site's contaminated waters and then evaluate and optimize a larger-scale system. Once the researchers at Fleming College's Centre for Advancement of Water and Wastewater Technologies (CAWT) complete the specific design, chemistry, and calibrations required, they will install and build a system on the mine site. CAWT researchers will evaluate the system's ability to treat the mine's contaminated waters in a "real world" environment and through seasonal variations. As a result, the mining company will be able to evaluate the system over several years with a goal to replace their costly wastewater treatment plant with a full-scale sustainable alternative. This research will contribute significantly to new knowledge in the field of eco-engineered bioreactors, especially as they are used to treat mining influenced waters. It will also provide the mining company with a sustainable eco-technology that they can implement at their mine sites globally.

在一座贵金属矿关闭后，这家矿业公司负责该矿场的长期环境管理，包括处理受污染的水。加拿大大多数矿山使用传统的废水处理厂来处理受污染的水。这些处理厂运营成本高，能源密集型，而且在环境上不可持续。这项研究的主要目标是完成一种自然的、长期的、低能耗的废水处理方法的详细设计，该方法专为处理特定的前安大略省金矿矿场的污水而量身定做，然后评估和优化一个更大规模的系统。一旦弗莱明学院水和废水技术促进中心(CAWT)的研究人员完成了所需的具体设计、化学和校准，他们将在矿场安装和建造一个系统。CAWT的研究人员将在“真实世界”环境中通过季节变化来评估该系统处理矿井污染水的能力。因此，这家矿业公司将能够在几年内对该系统进行评估，目标是用一种全面的可持续替代方案取代成本高昂的废水处理厂。这项研究将对生态工程生物反应器领域的新知识做出重大贡献，特别是当它们被用于处理受采矿影响的水时。它还将为这家矿业公司提供一种可持续的生态技术，他们可以在全球范围内的矿场实施。
