To investigate the influence of plant types on the pollution removal efficiency of drinking water treatment residue (DWTR) based constructed wetlands, a pilot-scale experiment was constructed, and the adsorption mechanisms for phosphate (PO43--P) were investigated. The results demonstrated that regardless of plant types, the DWTRs-based constructed wetlands exhibited a high removal efficiency for PO43--P, but the contribution of plants in improving the adsorption rate was relatively negligible. Additionally, the Langmuir isotherm model can describe the adsorption behaviors well, which exhibited high adsorption capabilities of 162.11 mg/g. Furthermore, the pseudo-secondorder model can describe the adsorption kinetics well, demonstrating chemical processes were the main force. This experimental study can provide theoretical guidance to enhance our understanding of the pollutant removal mechanisms in DWTRs-based constructed wetlands.
