Nitrification at cold temperatures in a biostyr reactor

该项目的目标是证明作为浸没式生物滤池运行的曝气生物滤池(BAF)处理系统能够在代表加拿大气候的寒冷温度下进行显著的硝化作用。这项研究解决了在极端环境条件下提高我们处理含有有毒污染物氨的废水的能力的迫切需要，例如加拿大所经历的情况。我们建议使用台式曝气生物滤池系统进行一系列精心计划和执行的实验室实验，然后在魁北克的一个处理设施进行一系列中试实验。拟议的研究涉及使用几种最先进的技术来表征反应堆系统中的生物膜(例如，共聚焦激光扫描显微镜、荧光原位杂交、扫描电子显微镜)。确定BAF系统在低温下对受污染废水进行硝化的潜力将对合作组织John Meunier Inc.具有重要价值。这项研究获得的技术信息将为JMI提供评估其技术增加目标市场的潜力的手段。我们的结果还将有助于在(I)硝化生物膜、(Ii)废水处理和(Iii)低温硝化方面的一般知识。

The objective of the project is to demonstrate that Biological Aerated Filtration (BAF) treatment systems that operate as immersed biofilters are capable of significant nitrification at cold temperatures representative of Canadian climates. The research addresses a critical need to improve our ability to treat wastewaters that contain the toxic contaminant ammonia under extreme environmental conditions such as those experienced in Canada. We propose to conduct a series of carefully planned and executed laboratory experiments using bench-top BAF systems followed by a set of pilot-scale experiments conducted at a Quebec treatment facility. The proposed research involves the use of several state-of-the-art techniques for the characterization of biofilm in the reactor systems (e.g., confocal laser scanning microscopy, fluorescence in-situ hybridization, scanning electron microscopy). Determining the potential of the BAF system for nitrification of contaminated wastewaters at low temperatures will be of significant value to the partner organization, John Meunier Inc. The technical information obtained as a result of this research will provide JMI with the means to evaluate the potential to increase their target market for their technology. Our results will also contribute to the general body of knowledge in the areas of (i) nitrifying biofilms, (ii) wastewater treatment and (iii) nitrification at cold temperatures.
