Integrated Wastewater Treatment for Bioresource and Bioenergy Recovery

引言 加拿大的政策正在推动对应用无害环境和可持续做法管理我们的可再生资源的需求。加拿大环境部提出了新的污水系统污水排放法规(WSER)，以监控加拿大的污水处理设施[1]，为满足污水排放要求所需的升级费用估计为100-130亿美元，其中大部分将由较小的市政当局承担[2]。拟议的研究计划旨在利用生态工程藻类系统处理城市污水，以应对加拿大的这些挑战。该研究计划将培训7名HQP(5名博士和2名硕士)，他们将在应用环境可持续性领域获得高度期望的技术技能，并担任废水处理和生物资源管理专业人员的领导职位。 建议的研究计划 长期目标是开发一种新的基于证据的方法，为加拿大气候设计生态工程废水处理系统，重点是综合生物资源管理。所进行的研究将使用实地监测、受控实验室调查和先进的统计分析方法来建立知识库，以实现这一总体目标。在短期内，该计划旨在更好地了解影响废水稳定塘(WSP)污水处理和消毒功能的动态相互作用，从而产生遵循循证方法的更强大的设计模型和指南；并调查微藻共培养与城市污水处理基础设施的整合，作为一种可持续的污水处理战略，具有下游回收藻类生物燃料的潜力。 研究成果 该研究计划将有助于在加拿大的WSP系统中使用被动系统来处理和抛光废水的最先进技术。预计通过实现这些目标而开发的知识可以转移到行业中，以便未来的可持续发展战略计划的设计可以遵循循证方法，从而产生有效的可持续发展战略计划系统。这将帮助面临可能昂贵的废水基础设施升级两难境地的市政当局满足日益严格的联邦废水排放准则。并使市政部门能够注重应用环境的可持续性。该研究计划还将解决目前在利用废水共培养藻类方面存在的严重知识差距，以及在综合生物资源管理方法中增加生物燃料下游回收的潜力。 HQP培训 加拿大市政当局的劳动力正在老龄化，对废水处理流出物的更严格的监管指导方针，以及对整合可持续方法的关注，使废水系统的管理更加复杂。这在加拿大市政当局和整个行业产生了对训练有素、具有高级技术和专业技能的专业人员的大量需求。拟议的研究计划将通过培训7名HQP使加拿大受益，这些HQP将在开发替代废水和废物管理技术和可持续环境方法方面获得高度期望的技术技能，重点是综合生物资源管理，以及工程专业管理技能。HQP将准备好担任市政、监管机构、省级部委和联邦部门以及咨询公司的废水专业人员的领导职位，增强加拿大在应用环境可持续发展方面的影响力能力。

INTRODUCTION Canadian policies are driving the demand for the application of environmentally sound and sustainable practices in managing of our renewable resources. Environment Canada has proposed new Wastewater Systems Effluent Regulations (WSER) to monitor wastewater treatment facilities in Canada[1] and required upgrades to meet effluent discharge requirements are estimated at $10-13 billion, the majority of which will be borne by smaller municipalities[2]. The proposed research program aims to address these Canadian challenges using eco-engineered algal systems for municipal wastewater treatment. The research program will train 7 HQP (5 PhD and 2 MASc) who will acquire highly-desired technical skills in the area of applied environmental sustainability and assume leadership positions as wastewater treatment and bioresource management professionals. PROPOSED RESEARCH PROGRAM The long-term objective is to develop a new evidence-based approach to designing eco-engineered wastewater treatment systems for Canadian climates with a focus on integrated bioresource management. The research conducted will use field-scale monitoring, controlled laboratory investigations and advanced statistical analysis methods to build the knowledge-base to achieve this overarching goal. In the short term, the program aims to develop a better understanding of the dynamic interactions influencing wastewater treatment and disinfection functions in wastewater stabilization ponds (WSPs) leading to more robust design models and guidelines that follow an evidence-based method; and investigate the integration of microalgae co-cultivation to municipal wastewater treatment infrastructure, as a sustainable wastewater treatment strategy with the potential for the downstream recovery of algal biofuels. RESEARCH OUTCOMES The research program will contribution to the state-of-the art in using passive systems to treat and polish wastewater in Canadian WSP systems. It is anticipated that the knowledge developed through the realization of these objectives can be transferred to industry so that future WSP design can follow an evidence-based method, leading to effective WSP systems. This will assist municipalities, faced with potentially costly wastewater infrastructure upgrade dilemmas for aging or inadequate WSP systems in meeting increasingly stringent federal wastewater effluent guidelines. and enable municipal with a focus on applied environmental sustainability. The research program will also address critical gaps that exist in the current state of knowledge with respect to the co-cultivation of algae using wastewater and the increase the potential for downstream recovery of biofuels in an integrated bioresource management approach. HQP TRAINING The workforce in Canadian municipalities is aging and stricter regulatory guidelines for wastewater treatment effluents and the focus on integrating sustainable approaches have made the management of wastewater systems more complex. This has created a large demand for highly trained professionals with advanced technical and professional skills in Canadian municipalities and across the industry. The proposed research program will benefit Canada by training 7 HQP who will acquire highly-desired technical skills in in the development of alternate wastewater and waste management technologies and sustainable environmental approaches with a focus on integrated bioresource management, as well as skills in professional management in engineering. HQP will be ready to assume leadership positions as wastewater professionals in municipalities, regulatory agencies, provincial ministries and federal departments, and consulting firms, enhancing Canada’s capacity for influence in applied environmental sustainability.
