摘要: Abstract The first-order removal model is widely used in constructed wetland design. suitability of this was tested to predict metal retention a young receiving agricultural and urban runoff. During two years, water samples for total dissolved analyses were collected every third day at both the inlet outlet. retained metals best during summer fall whereas winter significantly lower. predicted Fe Mn spring Zn from years. those periods, hydraulic times (HRTs) greater than 7 days provided maximum Fe, Mn, Zn. However, models failed fit summer, data almost under investigation (Fe, Cu, As) suggesting that HRTs (
