The invention relates to a method for reinforcing a surface flow artificial wetland system by using a biomembrane. A wetland plant system is arranged between a water inlet water distribution pipe and a water outlet water collection pipe of the system, and a biomembrane carrier is arranged in a plant root gap area. The method comprises the following steps of: 1, constructing a surface flow artificial wetland; 2, culturing and growing plants; 3, selecting the biomembrane carrier; 4, arranging and fixing the carrier; and 5, operating the wetland. The method has the advantages that: by combining the surface flow wetland with the biomembrane, the purifying capacity of the surface flow wetland is greatly improved while various advantages and an ecological service function of the conventional surface flow artificial wetland are kept, and the condition that a filter material is blocked in an underflow wetland is avoided. The biomass of microorganisms is increased by the biomembrane to improvethe purifying capacity of
