项目摘要

Wastewater treatment in Canada is currently undergoing a period of revision wherein stricter regulations have come into force or will come into force over the next several years. Specifically, industrial wastewater, in particular food and beverage wastewater, is characterise by high ammonia and phosphorous concentrations Both ammonia and phosphorous cause deleterious impacts on the receiving aquatic systems; ammonia results in both acute and chronic toxicity issues, including fish death, and phosphorous leads to eutrophication that may results in algae blooms, loss of dissolved oxygen with the potential for fish death as a results as well. The food and beverage industry produce effluents with high carbon, total nitrogen and phosphorous concentrations. The high concentration of carbon, nitrogen, phosphorous and the ammonium nitrogen (60 to 270 mg/L) could cause considerable toxic effects to aquatic life and might pose the risk of eutrophication. Biological treatment is the most common and economical means of carbon and ammonia removal from wastewater in Canada and throughout the world. However, conventional suspended growth aerobic or anaerobic biological treatment systems might not be capable of treating food and beverage industry wastewater with the these high carbon:nitrogen:phosphorous ratios. An aerobic granular sludge processes has the potential capacity to treat high organic loading rates and simultaneously removes nutrient through nitrification, denitrification and microbial phosphorous accumulation in a single reactor; however the application of this innovative technology to treat the food and beverage wastewater is not fully explored. In particular information on the start-up operation and performance of aerobic granules in the food and beverage wastewater is scarce. Thus, this research project is aimed at providing environmentally sustainable wastewater treatment options by investigating the aerated granular SBR startup operation, removal rates of carbon, nitrogen and phosphorous to develop a strategy for the development and maintenance of stable aerated granules for nutrient removal at the lab scale with future collaborative work aimed at pilot scale testing.
加拿大的废水处理目前正处于修订期,更严格的法规已经生效或将在未来几年内生效。具体而言,工业废水,特别是食品和饮料废水,其特点是氨和磷浓度高。氨和磷都会对接收水生系统造成有害影响;氨会导致急性和慢性毒性问题,包括鱼类死亡,而磷会导致富营养化,从而可能导致藻类大量繁殖、溶解氧损失,从而也可能导致鱼类死亡。食品和饮料行业产生碳、总氮和磷浓度较高的废水。高浓度的碳、氮、磷和铵态氮(60至 270 mg/L)可能会对水生生物造成相当大的毒性影响,并可能造成富营养化的风险。生物处理是加拿大和全世界废水中最常见、最经济的去除碳和氨的方法。然而,传统的悬浮生长需氧或厌氧生物处理系统可能无法处理具有这些高碳:氮:磷比例的食品和饮料工业废水。好氧颗粒污泥工艺具有处理高有机负荷率的潜在能力,并通过单个反应器中的硝化、反硝化和微生物磷积累同时去除营养物;然而这个应用 处理食品和饮料废水的创新技术尚未得到充分探索。特别是有关食品和饮料废水中好氧颗粒的启动操作和性能的信息很少。因此,该研究项目旨在通过调查曝气颗粒 SBR 启动操作、碳、氮和磷的去除率,提供环境可持续的废水处理方案,以制定开发和维护稳定的曝气颗粒以在实验室规模去除营养物的策略,以及未来针对中试规模测试的合作工作。
