丹麦奥胡斯即将成为全球首个用家庭污水和废水生成的能源驱动市政淡水供给系统的城市。通过修复,奥胡斯玛尔丽斯堡污水处理厂已能够生成运行丹佛斯电力电子公司所需能源1.5倍的电能,盈余的电能可用于驱动全市自来水供水系统,可为奥胡斯市内生活的20万人提供服务,其它剩余的电量则可销售给当地电网。丹佛斯电力电子公司利用家庭污水和废水形成沼气产生能量。废水被泵入充满细菌的38℃的蒸炼器中,产生沼气,随后这些气体被燃烧生成热量用于发电。该技术并不
Aarhus, Denmark is about to become the first city in the world to use a source of domestic sewage and waste water to drive a municipal freshwater supply system. Through repairs, the Aarhus Marrisburg Sewage Treatment Plant has been able to generate 1.5 times the energy needed to operate Danfoss Power Electronics. The surplus energy can be used to drive the city’s tap water supply system, which can be used in the city of Aarhus. 200,000 people provide services, and the rest of the electricity can be sold to the local grid. Danfoss Power Electronics uses domestic sewage and wastewater to generate biogas to generate energy. Wastewater is pumped into a bacteria-filled 38°C digester to generate biogas, which is then burned to generate heat for power generation. This technology is not
