Three-dimensional(3D)biofilm electrochemical method integrates the functions of both electrochemical method and biological method,and has the advantages of high degradation efficiency and energy saving.Through analyzing the characteristics of 3D biofilm electrochemical system,it is summarized that the system has the abilities to improve the level of hydroxyl radical with oxidation function,accelerate the efficiency of electron transfer,and increase the enrichment and activity of microbial community with degradation function.By analyzing the mechanism of the system for the efficient removal of pollutants,the optimization scheme is proposed from the process parameters(electrode material,reactor structure and electrode morphology)for constructing reactor.The influences of the operating conditions of the system on the removal performance of the system to pollutants is compared,and the system’s economic performance is evaluated.Finally,the development direction of three-dimensional biofilm electrochemical method in the future is proposed.
