The capability and structure of Ti/Sb2O5＋SnO2/α-PbO2/β-PbO2 anode was researched by SEMand XRD. This electrode was used in the treatment of acid flavine 2G simulated wastewater, and the effects of parameters on the removal efficiency of COD were also studied. The optimal parameters obtained are as follows, the current grade is 0.6 A, the electrolytic time is 6 h, the electrode distance is 32 mm, and the initial pH is 6.0. The experimental results indicate that the reactor could efficiently remove COD and increase the biodegradability of the wastewater.
