Abstract In order to improve the applicability of constructed wetlands in micro-polluted water, the impact of wetland influent pollution load on the system's effluent quality concentration and unit removal load was studied by tracking the constructed wetland demonstration project. The results show that the effluent quality concentration and unit removal load of wetland have a good linear (curve) correlation with the wetland water pollution load. The calculation of linear regression equation shows that the optimal NH4+-N, COD and TP influent loads are 3.8 g/(m2·d) and 62 g/(m2·d) and 755 mg/ (m2·d) when the constructed wetland with volcanic rock as the main substrate is used to treat micro-polluted water. At this time, the wetland effluent quality concentration can meet the Class IV water quality standard of "Surface Water Environmental Quality Standard" (GB 3838-2002). The research results can provide data references and technical support for the engineering design and application of constructed wetlands.
