摘要
在瑞士滑雪胜地Zermatt山顶的缆车站上,采用MBR现场处理厕所污水并进行回用。通过将处理出水几乎全部回用于厕所冲洗,使得对敏感山区环境的负面影响降至最低。除了氮被全部去除外,对磷的去除率也达到65%。介绍了该装置的运行情况、污泥的处理与管理,以及夏季低负荷长期运行时生物量的维持等。该装置的成功运行不仅为阿尔卑斯山区存在的类似问题提供了解决方案,而且对其他干旱地区通过污水再生回用以减少卫生用水消耗具有重要意义。
Toilet wastewater is treated and reused on-site by membrane bioreactor （MBR） at a cable car mountain station in the skiing resort of Zermatt. Negative impacts on the sensitive mountain environment are minimized by reusing close to 100% of the treated wastewater for toilet flushing. Besides 100% nitrogen removal, 65% of phosphorus was also eliminated. The operation situation of the device, sludge treatment and control, and maintenance of biomass during long-term low load operation in summer season were introduced. The successful operation of the device provides a solution to similar problems existing in the Alps region, and has a great importance for reducing sanitary water consumption by reclaiming and reusing wastewater in other arid regions.
