There is an ongoing paradigm shift; wastewater is often not considered a waste any more, but a source of valuable resources: nutrients (N: nitrogen, P: phosphorus, and K: potassium), energy and water. The recovery of phosphorus from municipal wastewater has gained a lot of attention because of limited phosphate rock reserves and associated geopolitics, and pollution of phosphate rock. At the WWTP of Leuven, Aquafin operates a full scale installation to recover phosphorus as struvite from digested sludge. This paper discusses the performance of the struvite plant, pollutants in the struvite, struvite use, and economics.
目前，人们的观念正在发生转变。现在，人们不再将污水视为废物，而是将其视为有价值资源的来源：营养物（N：氮、P：磷和 K：钾）、能源和水。由于磷酸盐岩储量有限以及相关的地缘政治问题和磷酸盐岩污染，从城市废水中回收磷引起了广泛关注。在鲁汶的污水处理厂，Aquafin 运营着一个从消化污泥中回收磷并将其转化为鸟粪石的全规模装置。本文讨论了鸟粪石工厂的性能、鸟粪石中的污染物、鸟粪石的用途和经济性。
