Most small communities in Canada rely on lagoon systems for their wastewater treatment. Approximately 800**of these treatment facilities across the country have been identified as potentially requiring upgrades to meet**new federal effluent regulations for organic matter, suspended solids and unionized ammonia (Canada Gazette,**2012). Additionally, there are increasingly stringent regulations of total phosphorus discharge to surface water**bodies to control the development of toxic blue-green algae. In Ontario, as with other provinces, wastewater**treatment plant effluent limits for total phosphorus are becoming more stringent, decreasing from typical values**of 1.0 mg/L to as low as 0.02 mg/L, depending upon the receiving water body (Sax, 2017).**This project will field test a discfilter technology developed by Veolia-Water to remove solids and phosphorus**from municipal lagoon effluent as well as from two post-lagoon polishing technologies: AnoxKaldnesTM**Moving Bed Biofilm Reactor (MBBR) system and a Constructed Wetland. The pilot study will take place at**two seasonal discharge lagoon sites in Eastern Ontario: the Town of Casselman aerated lagoon and the Town**of Alfred - facultative lagoon with constructed wetland. This project will optimize the discfilter with respect to**of a number of operating parameters including: filter mesh size, backwash frequency and removal of algae. The**knowledge gained from this study will help Veolia-Water provide enhanced treatment options for small**communities across Canada.

加拿大的大多数小社区依靠泻湖系统进行废水处理。全国大约有800个**这样的处理设施被确定为可能需要升级，以满足**关于有机物、悬浮固体和非离子化氨的新的联邦排放法规(加拿大公报，**2012)。此外，对地表水水体总磷排放的规定也越来越严格，以控制有毒蓝藻的发展。在安大略省，与其他省份一样，污水处理厂出水对总磷的限制正在变得更加严格，根据接收水体的不同，从典型的1.0毫克/L**下降到低至0.02毫克/L(SAX，2017年)。**该项目将现场测试威立雅-水公司开发的碟式过滤器技术，以去除城市泻湖污水以及两种泻湖后抛光技术的固体和磷**：AnoxKaldnerTM**移动床生物膜反应器系统和人工湿地。试点研究将在安大略省东部的**两个季节性泄洪泻湖地点进行：Casselman曝气泻湖和Alfred-带有人工湿地的兼职泻湖。该项目将根据许多运行参数中的**来优化滤盘过滤器，包括：滤网大小、反冲洗频率和除藻。从这项研究中获得的**知识将帮助威立雅-水公司为加拿大各地的小**社区提供强化的处理选择。
