摘要
Plants play an important role on constructed wetland (CW) purification, especially for its rhizosphere micro-environment. Oxygen supplying,, microbial biodegradation, hydraulic transmission and impovement nutrient are all closely related to the root micro-environment. However, after a period of running, plant residues and root exudates may affect the treatment performance of CWs, and clogging occurs. This paper reviews the both the positive and the negative roles of root micro-environment to develop promising strategies and proper management techniques in CWs.
