Modelling the integrated urban wastewater system based on water quality - MOSAIQUE (Modélisation du Système d'Assainissement Intégré basé sur la QUalité de l'Eau)

该项目旨在推进水量和水质综合模拟领域，以便更好地描述废水向接收水域的污染排放以及分配给废水运输和处理的业务成本。所获得的知识将有助于在可能的行动--业务变革或基础设施投资--之间确定优先次序，以减少污染和降低成本。将要开发的模型涵盖市政污水的产生、污水在分开和合流的污水渠中的输送以进行后续处理、污水处理厂的不同处理步骤以及通过污水溢流或经处理的污水将污染物排放到接收水中。特别强调了解和描述下水道中固体的运输、动态、组成和去向，以及对管理和运行下水道和污水处理厂基础设施的相应影响。**协同作用，将建立一个新的综合数据输入模型--流入生成器，该模型能够结合污水处理所发生的过程再现不同规模的市政当局的废水产生情况。该进水发生器将把从集成模型中收集的所有知识结合到一个易于使用的工具中，该工具可以更好地使用，即以更低的成本提高处理性能，并更快地设计污水处理厂。综合模型及其各个子模型将根据城市集水区范围内的案例研究数据进行彻底验证。**Mosaique项目是苏伊士处理技术加拿大公司发展计划的一部分。其结果将使加拿大和国际市政市场能够根据水质数据和高级处理设施的基于模型的设计来改善城市废水的管理。这代表着该公司的主要增长潜力，该公司目前的活动主要集中在使用传统方法的废水处理设施市场。因此，成功的商业化将与加拿大潜在的短期就业机会有关。******

This project aims to advance the field of integrated water quantity and quality modelling to better describe wastewater pollution emission to receiving waters and the operational cost allocated to wastewater transport and treatment. The gained knowledge will help prioritize between possible actions - operational changes or investment in infrastructure - for pollution abatement and cost reduction. The model to be developed covers the generation of wastewater from municipalities, its transport in separate and combined sewers for subsequent treatment, the different treatment steps at a wastewater treatment plant (WWTP) and the emission of pollutants into the receiving waters through sewer overflows or treated effluent. Particular emphasis is given to understand and describe the transport, dynamics, composition and fate of solids in sewers and the corresponding implications for managing and operating the sewer and WWTP infrastructure. **Synergistically, a new comprehensive data input model - influent generator - will be constructed that is able to reproduce the generation of wastewater at municipalities of various size combined with the processes happening in the sewershed. This influent generator will combine all the knowledge that is gathered from the integrated model into an easy-to-use tool which can be employed for better, i.e. enhanced treatment performance at lower cost, and faster WWTP design. The integrated model and its various submodels will be thoroughly verified against case-study data at city catchment scale.**The MOSAIQUE project is part of Suez Treatment Technologies Canada's growth plan. Its results will allow targeting Canadian and international municipal markets for improving the management of urban wastewaters based on water quality data and model-based design of advanced treatment facilities. This represents a major growth potential for the company whose activities currently focus mainly on the market of wastewater treatment facilities using traditional approaches. Successful commercialization would therefore be associated to potential short-term job creation in Canada. ******
