Performance and contaminants risks with a blackwater-only sewer system designed for energy and nutrient recovery under cold Canadian conditions

在全球和整个加拿大，城市在提供可持续的水和卫生服务方面面临挑战。随着大城市人口的增加和减少温室气体排放的需要，市政当局越来越难继续延长现有的污水收集和处理集中供水线路，更不用说维护老化的基础设施了。与传统的集中式服务相比，改善经济、环境和社会目标的一个选择是仅使用黑水的下水道(厕所和厨房食品流)，与家庭灰水分开。这项CRD建议的总体目标是开发一种有效且安全的耐冷黑水处理系统，该系统可以在加拿大寒冷的条件下从黑水中进行复杂的能量和养分回收。将演示最佳的运营条件和风险管理策略。参加这一CRD项目的高素质人员将获得学术和行业知识和经验，这将加强艾伯塔省和加拿大在废水处理管理方面的能力。

Globally and across Canada cities are challenged in providing sustainable water and sanitation services. With population expansion in major cities and the need to reduce greenhouse gas emissions, it has become more difficult for municipalities to keep extending existing centralized water supply lines for wastewater collection and treatment, let alone maintaining aging infrastructure. One option that improves upon economic, environmental and societal goals compared to conventional centralized services is a blackwater-only sewer (toilet and kitchen food streams) separate from household greywater. The overall objective of this CRD proposal is to develop an effective and safe psychrotrophic blackwater treatment system that can carry out complex energy and nutrient recovery from blackwater under cold Canadian conditions. Optimal operating conditions and risk management strategies will be demonstrated. The highly qualified personnel participating in this CRD Program will obtain academic and industrial knowledge and experience that will strengthen Alberta's and Canada's capacities in wastewater treatment management.
