摘要

Rapid urbanization and industrialization have resulted in the degradation of the water resources in China. Eutro-phication generally causes water quality deterioration, which makes it urgent to seek for a highly efficient eutrophic water treatment system. The constructed wetland is an effective and useful treatment system because of its simple technology and low operational cost. A field-scale constructed vvetland was built at Jiuxi town in China as the primary treatment measure before eutrophic lake water was drained to a riverine landscape. Water quality indices were determined from July to September 2009, and treatment operated regularly during the rainy season. The results showed the removal efficiency of total nitrogen (39-62%), ammoniacal nitrogen (61-84%), total phosphorous (5-10%), chlorophyll-a (93-98%), and indicate that the technology had a potential for chlorophyll-a as well as ammoniacal and total nitrogen removal.
