摘要

Constructed wetlands have become a good alternative to urban and industrial wastewater treatments. Because of the many interactions between the different parts that form the wetland, the design of these systems used to be very complex so a good design tool is required. Hybrid constructed wetlands mix the aerobic and anaerobic properties of vertical and horizontal subsurface flow constructed wetlands to improve COD, phosphorous and, especially nitrogen removal. A simulation of the concentration profiles of these compounds into a hybrid system constituted by four vertical flow constructed wetlands and a horizontal flow one with the K-C* model was achieved when the system treated an urban and a winery wastewater, respectively. Maximum limits of the flow rate to achieve the legislation limits of the different pollutants were calculated. Winery wastewater treatment required lower flow rates because of its higher organic loading. Because constructed wetlands had limited capacity to remove phosphorous, it was the most restrictive pollutant, requiring a lower flow rate.
