The landfill leachate evapotranspiration in soil?plant system with reed Phragmites australis
Using of the reed – Phragmites australis – is an effective method of landfill leachate disposal. In presented two years' study the effectiveness of leachate evapotranspiration from systems with reed was investigated. Daily evapotranspiration was in the range from 1.01 mm/d to 3.15 mm/d in the first year of research and from 2.68 mm/d to 4.94 mm/d in the second year. The research showed that the application of sewage sludge into the soil caused the increase in the vapourisation efficiency. Preliminary results of implemented soil-plant system with reed on landfill in Zakurzewo, Poland, showed that about 1100 m³ of leachate were evapotranspirated.
