Characterization and post-treatment of anaerobic bioreactor effluent treating biodegradable wastewaters

未经适当处理的城市和工业废水排放对湖泊、河流、含水层和海洋等水体的污染是一个主要的环境问题。这些排放物会对水资源的质量和公众健康产生不利影响。仍然需要更有效的、可持续的和经济的后处理/抛光方法，其可以被整合到现有的废水处理基础设施中以产生上级质量的流出物并满足严格的排放标准。厌氧生物反应器技术用于预处理/处理可生物降解的城市和工业废水的应用正变得流行，因为其固有的低污泥产量的特点，结合通过生产沼气的净能源效益的潜力。然而，残留的有机物，高浓度的营养物质，固体和其他感兴趣的污染物的存在下，提出了挑战，许多处理系统，以满足典型的排放限制，没有一个有效的后处理/抛光systems.The拟议的研究将旨在研究，开发和整合一个经济的后处理系统的生物反应器流出物的特性的基础上。该研究项目的成果有望为加拿大和其他国家的城市和工业提供一种新型的综合可持续污水处理替代方案，以控制环境污染。

Pollution of water bodies such as lake, rivers, aquifers and oceans by inadequately treated municipal and industrial wastewater discharges is a major environmental concern. These discharges can adversely affect the quality of water resources and public health. There remains a need for more effective, sustainable, and economical post treatment/polishing methods that can be integrated into existing wastewater treatment infrastructures to produce superior quality effluent and to meet the stringent discharge criteria.Application of anaerobic bioreactor technology for pretreatment/treatment of biodegradable municipal and industrial wastewaters is becoming popular, because of its inherent characteristics of low sludge production combined with the potential of net energy benefits through the production of biogas. However, presence of residual organics, high concentration of nutrients, solids and other contaminants of interest pose challenges for many of the treatment systems to meet typical discharge limits without an integration of efficient post-treatment/polishing system.The proposed research will aim to study, develop and integrate an economical post-treatment system based on characterization of bioreactor effluents. The results of this research program are expected to provide a novel integrated sustainable wastewater treatment alternative for municipalities and industries in Canada and other countries for environmental pollution control.
