ANNUAL CYCLE OF NITROGEN REMOVAL BY A PILOT-SCALE SUBSURFACE HORIZONTAL FLOW IN A CONSTRUCTED WETLAND UNDER MODERATE CLIMATE

KAPPELMEYER U. / KUSCHK P. / WIESSNER A. / et al. - ARTICLE DE PERIODIQUE - 2003

Long-term nitrogen cycle in a constructed wetland. Experiments were performed during 4 years. The season influences were evaluated in a moderate climate on the treatment performances. The oxygen exchange was an important condition on the nitrification rate. Denitrification was complete in summer and restricted in winter.
