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.

目前正在就“从废物流中回收资源”这一总主题研究三个相互关联的专题。 (a)磷和氮的去除和回收技术：目的是继续和扩展对本申请人来说相对新的课题的研究，即从富营养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上流反应器系统，安装在UBC、位于Agassiz的乳品教育研究中心（DERC），以及位于温哥华大都会Announcement的新Announcement废水处理中心（AWC）。重点是“鸟粪石”肥料的形成、造粒和优化反应器条件。 (b)先进的污水污泥处理：目标是推进污水污泥处理，重点是高温处理，以及过氧化物微波（PM）处理-朝着零污泥生产的最终目标。设施包括一个先进的生物营养物去除（BNR）中试工厂，一个中试规模的PM系统和一个嗜热的污泥处理设施（NST）在鲑鱼臂，不列颠哥伦比亚省目前的研究集中在联合污泥的处理，从消化池上清液中回收P，从NST系统中生产挥发性脂肪酸（VFA），污泥破坏和提高甲烷生产用于发电。 (c)高氮废物的处理：目标是扩大/按比例扩大关于为处理含氮废水而选择的生物工艺（固定介质、厌氧氨氧化工艺）的“优化”研究，以及一种新的受知识产权保护的“氨裂解器”技术，使用鸟粪石（肥料）颗粒进行焙烧和再循环。重点仍然是养分回收，能源生产，并减少最终污水排放的毒性。
