【前言】污水厂作为水环境质量改善的主要贡献者,追求相对高标准排放对环境改善是有益的。但是,活性污泥工艺诞生110年以来,一直是市政基础设施高能耗、高碳排的主要贡献者。双碳战略下,如何实现污水厂设计、建造及运行范式的转变,将污水厂由政府的“成本项”变为环境价值贡献者甚至是社会经济价值提供者,无疑这是未来污水厂传统范式的转变方向。

Paul Lavender, UK water utilities director at Royal HaskoningDHV told media: "Biogas is already extracted from sewage sludge but adding the recovery of useful biopolymers moves the industry higher up the value chain – it's potentially game-changing."

He added: "The global liquid polymer market is worth €1.2 trillion annually and is highly fossil fuel dependent, yet the nation's water treatment plants offer us a natural source of biopolymers. This new pilot project won't just demonstrate the extraction technology but will develop use cases by involving the whole supply chain including academia, commercial product developers, and blue-chip end-users."
