The invention discloses a method for alleviating filler pollution by coupling biological electrochemistry and artificial wetlands. The method is implemented on the basis of a biological electrochemical assistance type artificial wetland system, and comprises the following steps: 1) assembling the biological electrochemical assistance type artificial wetland system; 2) performing rock cultivation on activated carbon particles of an anode layer to form an electricity-generating biological film; 3) continuously operating sewage treatment, testing the specific surface area of the fillers by a fully-automatic physical adsorption instrument after stably operating for 4 months and comparing the specific surface area with that of a wet land layer. The method is used for treating sewage on the basis of the biological electrochemical assistance type artificial wetland system while alleviating the pollution problem of the fillers in the wetland treatment method, has double effects of generating electricity and alleviati
