Microbial fuel cell(MFC) with energy microalgae biocathode can be simultaneously achieved pollution control, zero carbon emissions, power generation, CO2 capture, and algae biodiesel and other valuable residue recycling multiple effects, has broad application prospects.  In this paper, the innovative design of their own beneficial to the Growth of the cathode MFC reactor as an experimental model, the first to start its normal operation liquid cathode, anode producing electricity Enrichment be mature, stable power battery production were investigated after the normal cathode run, adding algae into the cathode, the cathode electrode of Pt and the cathode light of this ongoing cycle of four different operating conditions, the MFC producing electricity, the growth of Chlorella and dissolved oxygen conditions in the cathode, and the COD treatment situation of the artificial water in anode . The results show that adding Chlorella into the cathode production after the MFC power level, dissolved oxygen level of the cathode, anode COD artificial wastewater treatment rate had a significant increase and, ultimately, the greatest period of continuous light cathode output voltage is 483.1mv, is 4.8 times as the normal operation ; the maximum output power density is 27.5mW / m, is 28.9 times as the normal operation ; the internal resistance is 480.7Ω, is 0.4 times as the normal operation; the average level of dissolved oxygen in cathode is stable
