摘要：

Constructed wetlands offer green and sustainable treatment, but how long will they really work? A wetland in northeastern Minnesota has been successfully treating mine drainage for almost 20 years. The primary removal processes include adsorption, ion exchange and complexation. These reactions have a finite lifetime since they depend on the existence of suitable removal sites. Removal will eventually cease unless new removal sites are generated or added. New sites are generated each year as vegetation dies and decomposes. For this wetland, the annual increase in metal removal capacity is about equal to the annual metal input; theoretically providing sustainable treatment.
