Aerobic granular sludge in continuous flow reactor configuration**

加拿大的污水处理厂（WWTP）是由联邦和省法规强制升级到完全去除导致河流和湖泊恶化的有机物和施肥营养物质。现有的污水处理厂使用长连续流反应器（CFR）。这类工厂的传统升级将需要大量增加土地（通常很难在现场获得）和资本成本，以及巨大的运营成本，这对市政当局来说可能是压倒性的。最近在加拿大以外展示的一种新型高效的好氧颗粒污泥（AGS）技术，有可能通过占用更少的土地和更低的运营成本来解决这些问题。然而，AGS技术仅作为顺序间歇反应器技术或AGS- sbr提供，这是一个不连续过程，不适合改造/升级CFR过程，目前在加拿大约90%的市政工厂中存在。建议开发一种突破性的好氧颗粒污泥连续流反应器或AGS-CFR，其配置将具有现有连续流系统中颗粒污泥的关键元素。在一个现有的污水处理厂，一个大型的中试系统以未经处理的污水为原料，用以制订设计准则、控制、监测和操作参数，以促进扩大规模至全面规模。这一突破性的新AGS CFR工艺的要素已经由申请人在小范围内进行了演示。该项目对加拿大市政当局具有重要的战略意义，因为AGS-CFR的应用将通过将该工艺与现有基础设施相结合，从而实现全面的营养物去除，并实际降低运营成本。工业合作伙伴AECOM对在世界各地的设计工作中采用该技术有直接的兴趣。温尼伯市公用事业合作伙伴对此非常感兴趣，因为它一直面临着过高的成本和预期的主要工厂常规升级规模，因此将ag - cfr技术视为实现更可承受的资本和运营成本的替代解决方案

Canada's wastewater treatment plants (WWTP) are mandated by federal and provincial regulations to upgrade to full removal of organics and fertilizing nutrients which lead to deterioration of rivers and lakes. Existing WWTP use long, continuous flow reactors (CFR). A traditional upgrade of such plants would require significant increase of land (often hardly available on site) and capital costs as well as carry large operating costs, which could be overwhelming for a municipality. A new and highly effective technology of aerobic granular sludge (AGS) recently demonstrated outside Canada, has potential to offset these problems by requiring less land and carrying much lower operating costs. The AGS technology is however offered only as a sequencing batch reactor technology or AGS-SBR, which is a discontinuous process and is ill-suited to retrofit/upgrade the CFR process present in some 90% of Canadian municipal plants. It is proposed to develop a ground-breaking aerobic granular sludge continuous flow reactor or AGS-CFR, in a configuration that would feature key elements of granular sludge in an existing continuous flow system. A large pilot scale system fed with raw wastewater at an existing wastewater treatment plant will be used to develop design criteria, control, monitoring and operational parameters which will facilitate scale-up to full scale. The elements of this breakthrough new AGS CFR process have already been demonstrated by the Applicants in small scale. The project is of strategic importance to Canadian municipalities as application of AGS-CFR will allow for implementation of full nutrient removal by fitting the process into existing infrastructure and actually lowering the operating costs. The industrial partner AECOM has an immediate interest in adopting the technology in its design work around the world. The City of Winnipeg utility partner is vitally interested as it has been faced with prohibitive costs and size of anticipated conventional upgrade of its main plant and therefore views the AGS-CFR technology as the alternative solution to arrive at more affordable capital and operating costs.**
