Phosphorus and nitrogen removal and recovery technologies; innovation in waste treatment process streams, for resource recovery.

目前正在研究三个相互关联的主题，即“从废物中回收资源”这一总主题。 (A)磷和氮的去除和回收技术：目标是继续并扩大对申请者的一个相对较新的主题的研究，即从营养丰富的废物中去除磷和氮并进行回收。设施包括安装在UBC的实验室规模、中试规模和商业规模的升流反应器系统，位于不列颠哥伦比亚省阿加西的乳业教育研究中心(DERC)，以及新的Annacis废水中心(AWC)，Metro Vancouver Annacis，WWTP。重点是“鸟粪石”肥料的形成、造粒和优化的反应堆条件。 (B)高级废水污泥处理：其目标是推进废水污泥处理，重点是高温处理以及过氧化氢-微波(PM)处理--朝着零污泥生产的最终目标迈进。设施包括位于不列颠哥伦比亚省萨蒙阿姆的高级生物营养去除(BNR)中试工厂、中试规模PM系统和高温污泥处理设施(TAD)。目前的研究重点是组合污泥的处理、从消化池上清液中回收磷、TAD系统生产挥发性脂肪酸(VFA)、污泥破坏和提高甲烷产量以用于发电。 (C)高氮废物处理：目标是扩大/扩大对用于处理含氮废水的生物工艺(固定介质、厌氧氨氧化工艺)的“优化”的研究，以及使用鸟粪石(肥料)颗粒进行焙烧和回收的受知识产权保护的“氨裂解”新技术。重点继续放在养分回收、能源生产和最终污水排放的毒性降低上。

Three interrelated topics are being researched, on the overall theme of "resource recovery from waste streams". (a) Phosphorus and Nitrogen Removal and Recovery Technology: The objective is to continue and expand on research into a relatively new topic for this applicant, phosphorus (P) and nitrogen (N) removal and recovery from nutrient - rich wastes. Facilities include lab-scale, pilot scale and commercial-scale up flow reactor systems, installed at UBC, the Dairy Education Research Centre (DERC) at Agassiz, B.C., and at the new Annacis Wastewater Centre (AWC), Metro Vancouver Annacis, WWTP. The focus is on "struvite" fertilizer formation, pelletization and optimized reactor conditions. (b) Advanced Waste-Water Sludge Treatment: The objective is to advance waste-water sludge treatment, with an emphasis on thermophilic treatment, as well as peroxide-microwave (PM) treatment - toward the ultimate goal of zero-sludge production. Facilities include an advanced biological nutrient removal (BNR) pilot plant, a pilot scale PM system and a thermophilic sludge treatment facility (TAD) in Salmon Arm, B.C. Current research is focused on treatment of combined sludges, recovery of P from digester supernatant, production of volatile fatty acids (VFA) from TAD systems, sludge destruction and enhanced methane production for energy generation. (c) Treatment of High Nitrogen Wastes: The objective is to expand/scale-up research on "optimization" of biological processes (fixed media, Anammox process) chosen for treatment of N-laden wastwaters and a new IP-protected "ammonia cracker" technology, using struvite (fertilizer) pellets for roasting and recycling. The emphasis continues to be on nutrient-recovery, energy production, and toxicity reduction of final effluent discharges.
