摘要：In this study, the kinetic models of pollutant degradation in different wetlands were studied. The kineticequations were deduced and the kinetic simulation of the main pollutants such as NH3-N and TN wascompleted by the experimental data, and the dynamics of the pollutant degradation simulation modelwere applied to simulate the effect of the reaction kinetics model on the removal of contaminants inhorizontal steel slag subsurface wetland (HSSSW) and horizontal volcanic subsurface wetland(HVSW). The results showed that the first order reaction kinetics model could obviously simulate theeffect of main pollutants such as NH3-N and TN in two kinds of subsurface wetlands. The correlationcoefficient R2 of the dynamic linear model was 0.9640 and 0.9600 in HSSSW, respectively, and thecorrelation coefficient R2 of the HVSW was 0.9365 and 0.9709, respectively. The degree of fitting andcorrelation was very good. Besides, the simulation results showed that the degradation of the mainpollutant was of great reference value for the design and operation of the practical subsurfacewetland.
