Sustainable resource recovery technologies for municipal wastewater treatment plants

该提案旨在将UBC开发的领先技术整合到高效的污水污泥处理系统中，用于污泥固体破坏，营养物释放和回收，以及联合Abbotsford使命环境系统（JAMES）废水处理厂的生物能源生产，Abbotsford，BC。该集成系统将包括UBC专利微波处理工艺，高速鸟粪石结晶器和创新的厌氧消化系统。微波系统不仅可以减少污泥固体含量，还可以促进营养物质释放到溶液中。因此，磷和氮可以鸟粪石的形式回收，鸟粪石是通过随后的结晶过程的缓释肥料。通过创新的厌氧消化系统也可以实现更有效的生物能源生产。本项目需要完成的任务包括：1）。UBC设计的中试规模连续流微波处理系统的测试; 2）.对新研制的鸟粪石高速结晶器的回收效率进行了测试和评价; 3）.检验两相厌氧消化系统的性能; 4）.在JAMES污水处理厂运行集成系统;以及5）。建立这一综合系统的设计标准和操作规程。该项目的最终成果将是一个完全开发的“概念验证”综合污水污泥处理系统。本项目开发的废物管理、污泥减量和资源化系统将对污泥管理产生重大影响，并为污水处理行业提供可观的经济和环境效益。

This proposal is to integrate UBC developed leading edge technologies into a high efficient sewage sludge treatment system for sludge solids destruction, nutrient release and recovery, as well as bioenergy production at the Joint Abbotsford Mission Environmental System (JAMES) wastewater treatment plant, Abbotsford, BC. The integrated system will consists of a UBC patented microwave treatment process, a high-rate struvite crystallizer and an innovative anaerobic digestion system. The microwave system would not only reduce sludge solids content, but also facilitate the release of nutrients into solution. Phosphorus and nitrogen can thus be recovered in the form of struvite, which is a slow release fertilizer via a subsequent crystallization process. More efficient bioenergy production can also be achieved by an innovative anaerobic digestion system. The tasks required in this project include: 1). testing of the UBC-designed pilot-scale continuous flow microwave treatment system; 2). testing and evaluating the recovery efficiency of the newly developed high-rate struvite crystallizer; 3). examining the performance of a two-phase anaerobic digestion system; 4). operating the integrated system at JAMES wastewater treatment plant; and 5). establishing the design criteria and operating protocols of this integrated system. The final outcome of the project will be a fully developed 'proof-of-concept' integrated sewage sludge treatment system. The improved waste management, sludge reduction and resource recovery system developed in this project will have a significant impact on sludge management, and offer substantial economical and environmental benefits for the wastewater treatment industry.
