Using first order plug-flow reactor model, BOD5 removal rate constants of the whole wetland system were estimated to be 0.50 1/day (at 24℃) and 0.76 1/day (at 24℃) in the start-up and stable phase, respectively. These values were comparable to or even higher than the value of deoxygenation rate constant, 0.23 1/day (at 20℃), that is normally used in the river water-quality model.
