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.****

正在研究三个相互关联的主题，总体主题是“从废物流中回收资源”。****(a) 磷和氮的去除和回收技术：目标是继续并扩展对一个相对较新主题的研究本申请人研究了从营养丰富的废物中去除和回收磷（P）和氮（N）。设施包括实验室规模、中试规模和商业规模的升流反应器系统，安装在 UBC、不列颠哥伦比亚省 Agassiz 的乳品教育研究中心 (DERC) 以及大温哥华地区 Annacis 污水处理厂的新 Annacis 废水中心 (AWC) 。重点是“鸟粪石”肥料的形成、造粒和优化反应器条件。**(b) 先进的废水污泥处理：目标是推进废水污泥处理，重点是高温处理以及过氧化物处理-微波（PM）处理——朝着零污泥产生的最终目标迈进。设施包括位于不列颠哥伦比亚省萨蒙阿姆的先进生物营养物去除 (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、从消化器上清液中回收磷、从 TAD 系统生产挥发性脂肪酸 (VFA)、污泥破坏和提高用于能源生产的甲烷产量。**(c) 高氮废物的处理：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”研究以及新型受知识产权保护的“氨裂解装置”技术，使用鸟粪石（肥料）颗粒进行烘烤和回收。重点仍然是营养物回收、能源生产和最终废水排放的毒性降低。****
