    The invention provides a combined installation of iron-carbon microelectrolysis - microbial fuel cell - constructed wetland for treating 5 wastewater containing pesticides. They are, in turn from left to right, the artificial simulated wastewater pool, peristaltic pump and the combined iron-carbon microelectrolysis - microbial fuel cell - constructed wetland system. The wastewater in the artificial simulated wastewater pool is delivered by the peristaltic pump through the water distribution pipe to the combined system. The 10 invented installation is provided with a trapezoidal compartment for iron-carbon microelectrolysis on the bottom and the top. First of all, this considerably improves the biodegradability of wastewater. By decomposing macromolecular phosphate ester organic pesticides into small molecules, it improves pollutant removal efficiency and electron transfer efficiency as well as the treatment effect 15 and electricity-generating effect of follow-up constructed wetland microbial fuel cell.
