Nitrification at cold temperatures in a biostyr reactor

该项目的目的是证明，生物曝气过滤（BAF）处理系统，作为浸没式生物过滤器，能够在代表加拿大气候的低温下进行显着的硝化作用。这项研究解决了一个关键的需要，以提高我们的能力，处理废水含有有毒污染物氨在极端的环境条件下，如那些在加拿大经历。我们建议进行一系列精心策划和执行的实验室实验，然后在魁北克处理设施进行了一组中试规模的实验，使用台式曝气生物滤池系统。拟议的研究涉及使用几种最先进的技术来表征反应器系统中的生物膜（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对合作组织John Meunier Inc.具有重要价值。通过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潜力的手段。我们的研究结果也将有助于（i）硝化生物膜，（ii）废水处理和（iii）低温硝化等领域的一般知识。

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.
