Flow injection nitrogen and phosphorus analyzer

所要求的研究设备将用于分析水和废水中的营养物-氮和磷。 目前，养分去除是马尼托巴环境议程上最大的问题。 申请人担任国际水协会营养物去除和恢复专家组主席，并且已经看到营养物问题（湖泊和溪流的过度施肥，也称为富营养化）成为世界各地的首要问题。 申请人在过去的二十年中一直使用30年的比色自动分析仪进行生物营养物去除，该比色自动分析仪虽然不断翻新和升级，但已经达到其功能寿命的极限，并且不能提供所需的质量，也不能处理在环境工程实验室中分析的样品的数量。 土木工程和生物系统工程的学生共享实验室（环境实验室是相邻的），都需要新的设备进行研究，例如：硝化（氨氧化）在低温下（黄先生）和缺氧胁迫后（黄女士）;臭氧处理生物质后的总氮去除生物膜反应器中的脱氮自养反硝化作用（Celmer女士、Hwang先生、Rezania博士）;利用工业废物或碳生成进行脱氮（Chen先生）;在红河三角洲收获大型植物以防止养分循环（Grosshank先生）;颗粒活性污泥反应器的养分去除（周女士）;厌氧氨去除（Jaroszynski先生）;膜生物反应器的粪便处理（杨先生）。 我们的工作有经济效益。 仅温尼伯就面临着超过10亿B美元的废水基础设施和三个工厂升级的潜在支出。 在营养物去除过程和相关固体管理方面的任何改进都将转化为降低加拿大纳税人的负担。

Research equipment requested is going to be used in analysis of nutrients - nitrogen and phosphorus in water and wastewater.  Currently nutrient removal is the biggest issue on the environmental agenda in Manitoba.  The Applicant chairs the International Water Association's specialist group on Nutrient Removal and Recovery and has seen the nutrient problem (over-fertilization of lakes and streams also called eutrophication) becoming number one priority around the world.  The Applicants have been engaged in biological nutrient removal for the last two decades using a 30 years old colorimetric auto-analyzer, which although continuously refurbished and upgraded, has reached the limit of its functional life and cannot provide quality required nor process the numbers of samples that are analyzed in the environmental engineering laboratories.   The Civil Engineering and Biosystems Engineering students share the laboratories (the environmental laboratories are contiguous) and all need the new equipment to conduct research for example on: nitrification (ammonia oxidation) in cold temperatures (Mr Hwang) and after anoxic stress (Ms Wong); total nitrogen removal after ozone treatment of the biomass (Ms Dytczak); nitrogen removal in biofilm reactors (Ms Celmer); autotrophic denitrification (Ms Celmer, Mr Hwang, Dr Rezania); use of industrial waste or generation of carbon for denitrification (Mr Chen); macrophyte harvesting to prevent nutrient recycle in the Red River delta (Mr Grosshank); nutrient removal in granular activated sludge reactors (Ms Zhou); anaerobic ammonia removal (Mr Jaroszynski); manure treatment in membrane bioreactors (Mr Yang).   Our work has economic benefits.  Winnipeg alone is facing over $1 B potential expenditures on wastewater infrastructure and upgrades to its three plants.  Any improvements in the nutrient removal process and associated solids management will be translated to lower burden to the Canadian taxpayer.
