Organic Slurry Solids Destruction and Nutrient Solubilization

这项研究计划的目标是开发从有机废物浆液中回收资源的创新处理技术，如城市污水污泥、动物粪便和食品加工废物。不列颠哥伦比亚大学(UBC)正在开发的这些技术包括获得专利的微波增强高级氧化工艺(MW-AOP)、射频氧化工艺(RF-OP，正在申请专利)和鸟粪石专利结晶工艺。MW-AOP和RF-OP处理都是固体销毁技术，可能会改变有机废物泥浆的处理和处理方式。通过分解有机泥浆中的固体，不仅高相对分子质量的有机物被转化为易于生物降解的低相对分子质量的可溶化合物，而且有价值的营养物质被溶解并释放到经过MW-AOP或RF-OP处理的溪流中，在那里可以通过结晶过程或其他方法轻松地回收它们。在现有的污水处理设施中采用UBC开发的MW-AOP或RF-OP将使处理方案中的其他工艺更加高效。通过鸟粪石(磷酸铵镁)结晶过程回收磷为废水工业提供了一种防止营养污染的有效方法，并生产出可重复使用的有价值的缓释肥料产品。MW-AOP和RF-OP都能够实现非常低的污泥产量，不需要或几乎不需要城市污水处理厂的污泥浪费。这些技术不仅将有助于降低污水处理厂的运营成本，还将有助于生产A类生物固体，这是一种宝贵的土壤改良剂/肥料。UBC正在开发的这些技术将保障水质并改善废水管理，这对可持续发展的经济、环境和社会方面至关重要。它还将使废水处理行业在环境上更可持续，在经济上更可行。所开发的技术有很大的商业化潜力，并将对各工业部门(农业和食品加工、污水处理等)产生非常重大和积极的影响。这一研究计划将为有志于在重要的环境工程领域从事职业生涯的研究生和本科生以及博士后研究员(PDF)提供极好的培训机会。在研发过程中，将鼓励研究生和PDF参加研讨会、国际会议，使废水处理行业受益于所开发工艺的“技术转移”。

The goal of this research program is to develop innovative treatment technologies for resource recovery from organic waste slurries, such as municipal sewage sludge, animal manure and food processing wastes. These technologies being developed at the University of British Columbia (UBC) include a patented microwave enhanced advanced oxidation process (MW-AOP), a radiofrequency-oxidation process (RF-OP, patent pending) and a proprietary struvite crystallization process. Both the MW-AOP and the RF-OP treatments are solids destruction technologies that could change the way organic waste slurries are treated and handled. By breaking up solids in organic slurries, not only higher molecular weight organics are converted into lower molecular weight soluble compounds, which are readily biodegradable, but also valuable nutrients are solubilized and released into the MW-AOP or RF-OP treated stream, where they can be easily recovered via a crystallization process or other means. Adopting the UBC developed MW-AOP or RF-OP into existing wastewater treatment facilities will make other processes in the treatment scheme much more efficient. Recovery of phosphorus through the struvite (magnesium ammonium phosphate) crystallization process offers the wastewater industry an efficient way of preventing nutrient pollution, and producing a valuable slow-release fertilizer product for reuse. Both MW-AOP and RF-OP have the capability of achieving a very low sludge yield, with no or little sludge wasting required from municipal wastewater treatment plants. Not only will these technologies help in reducing the cost of wastewater treatment plant operation, but also in producing Class A bio-solids, a valuable soil conditioner/fertilizer. These technologies being developed at UBC would safeguard water quality and improve wastewater management that are vital for economic, environmental and social aspects of sustainable development. It would also make the wastewater industry more environmentally sustainable and economically viable. There is a great potential for commercialization of the technologies developed, and will have a very significant and positive impact on various industrial sectors (agricultural and food processing, sewage wastewater treatment, etc.). This research program will provide excellent training opportunities for students, both graduate and undergraduate, and also post-doctoral fellows (PDF), who are interested in pursuing their careers in the important environmental engineering field. During the course of the R&D program, graduate students and PDFs will be encouraged to participate in seminars, international conferences, so that the wastewater treatment industry will benefit from "technology transfer" of the developed processes.
