摘要
基于可持续污水处理理念,荷兰2008年制定出未来污水处理的NEWs框架,即未来污水处理厂将是营养物(Nutrient)、能源(Energy)与再生水(Water)的制造工厂(factories)。NEWs框架强调资源与能源回收,并示范了各种不同回收目的可能采取的工艺步骤(概念工艺)。然而,NEWs框架并不是对既有工艺的否定,也不提倡盲从新技术,而是要求荷兰既有污水处理厂按框架内容、因地制宜地选择适合自己的升级改造工艺方案。首先介绍NEWs框架与概念工艺,并在此基础上选择一些有代表性的污水处理厂,总结和归纳它们的升级改造目标、过程以及预期效果。
The concept of sustainable wastewater treatment created the framework of NEWs for fu- ture wastewater treatment plants in the Netherlands in 2008, which is described to be nutrient ＋ energy ＋ water factories （NEWs）. The framework of NEWs emphasizes energy/resource recovery from wastewater and also proposes some conceptual processes for different targeted recovery. However, the framework of NEWs does not deny existing processes and does not advocate blindly following new technol- ogies either. In other ways, the framework of NEWs expects to upgrade WWTPs towards NEWs by acting according to circumstances. The framework and conceptual processes of NEWs were introduced, and some WWTPs under upgrading or to be upgraded were described.
