主　　题：Electrocoagulation Bipolar electrodes Municipal wastewater Simulations 

摘      要：The design of electrodes is crucial to electrocoagulation process(EC),specifically,with respect to pollutant removal and energy *** EC,the mechanisms for interaction between different electrode arrangement and electrode reactions remain *** work presents an integrated EC process based on horizontal bipolar electrodes(BPEs).In the electrochemical cell,the graphite plates are used as driving cathode while either Fe or A1 plates serves as driving anode and *** BPEs are placed horizontally between the driving *** municipal wastewater treatment,the pollutant removal efficiency and energy consumption in different configurations of twodimension electrocoagulation(2D-EC)system with horizontal BPEs were *** removal efficiency of turbidity,total phosphorus and total organic carbon increased significantly with the number of *** that the energy consumption for TP removal decreased by 75.2%with Fe driving anode and 81.5%with A1 driving anode than those of 2D-EC,*** addition,the physical field simulation suggested the distributions of potential and current in electrolyte and that of induced charge density on BPE *** work provides a visual theoretical guidance to predict the distribution of reactions on BPEs for enhanced pollutant removal and energy saving based on electrocoagulation process for municipal wastewater treatment.
