The development of partial nitrification (PN)/Anammox-based technology with ozonation as a pre-treatment is the main objective for this two-year project proposal for a NSERC Alliance Mission grant. The process uses a special BioCAST bioreactor that is a potentially viable ammonia nitrogen removal from gold mine wastewater in Quebec due to significantly lower costs, energy consumption and solid waste generation. High levels of contamination with nitrogen and other components and high salinity are particularly problematic for mining companies. The main objectives are to: (1) investigate the potential application of PN/Anammox process for simultaneous removal of nitrogen-based contaminants from gold mine, (2) evaluate pre-treatment using ozone microbubbles, (3) train highly qualified personnel (HQP) in mine water management and (4) strengthen the collaboration between the mining and water industries and academia to enable adoption of the nitrogen removal processes. The project is a collaboration between Agnico Eagle Mines Ltd., Concordia, UQAT and BioCAST Systems for the training of HQP (undergraduate, Masters, and post-doctoral levels) for future employment in the mining industry. The project includes the following phases at pilot scale: (i) Characterization of the wastewater effluents; (ii) evaluation of an ozonation pre-treatment with microbubbles; (iii) evaluation an PN/Anammox-based treatment system; (iv) evaluation of a combined pretreatment with the biological treatment system dentification of important factors influencing the performance and operation of the developed treatment system, and (v) technical, environmental, social and economic assessment of this process train for its incorporating into the company existing wastewater treatment at active gold mine sites. The water treatment systems will enable the mining companies to reduce operating costs as well as energy and sludge requirements, improve the potential for water reuse, protect the environment and enable the improvement of their environmental practices and their public image. These research orientations will contribute and foster an integrated approach for understanding the water-energy nexus in Canada and internationally.

以臭氧为治疗的局部硝化（PN）/基于Anammox的技术的开发是NSERC Alliance Mission Grant的这项为期两年的项目建议的主要目标。该过程使用一种特殊的生物播种生物反应器，该生物反应器是从魁北克的金矿废水中去除氮的潜在可行的氨，由于成本明显降低，能源消耗和固体废物产生。对于矿业公司而言，对氮和其他成分和高盐度的高度污染尤其有问题。主要目的是：（1）研究PN/Anammox过程的潜在应用，同时清除金矿中的基于氮的污染物，（（2）使用Ozone Microbubbles评估预处理，（3）培训高素质的人员（HQP）在矿山水管理中（HQP）在矿山水管理中（HQP）在矿山水管理中，并（4）（4）增强了矿物和水上和水上的协作，以促进矿床和水上和水上的协作。 该项目是Agnico Eagle Mines Ltd.，Concordia，UQAT和生物播种系统，用于培训HQP（本科生，硕士和博士后水平），以在采矿行业的未来就业。该项目包括以下阶段，以试点规模：（i）废水废水的表征； （ii）用微泡对臭氧的预处理评估； （iii）评估基于PN/ANAMMOX的治疗系统； （iv）对影响开发治疗系统的性能和运行的重要因素的生物处理系统的合并预处理评估，以及（v）对该过程培训的技术，环境，社会和经济评估，以将其纳入现有的活跃金矿场现有的废水处理中。水处理系统将使矿业公司能够降低运营成本，能源和污泥的要求，提高水资源的潜力，保护环境，并改善其环境实践和公众形象。这些研究取向将有助于并促进一种综合方法，以理解加拿大和国际上的水能Nexus。
