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。这些排放会对水资源质量和公众健康产生不利影响。仍然需要更有效、可持续和经济的后处理/抛光方法，这些方法可以整合到现有的废水处理基础设施中，以产生高质量的废水并满足严格的排放标准。应用厌氧生物反应器技术预处理/处理可生物降解的城市和工业废水正变得越来越受欢迎，因为其固有的低污泥产量的特点，结合潜在的净能源效益，通过生产沼气。然而，残留有机物、高浓度营养物、固体和其他污染物的存在对许多处理系统构成了挑战，因为没有集成有效的后处理/抛光系统，无法满足典型的排放限制。本研究旨在研究、发展及整合一套基于生物反应器废水特性的经济后处理系统。该项目的研究结果有望为加拿大和其他国家的市政和工业提供一种新的综合可持续废水处理替代方案，用于环境污染控制。

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.
