The invention relates to a metal oxide electrode used for the treatment of organic wastewater and a production method thereof. The technical proposal the following steps of: sequentially boiling and etching the industrially pure titanium sheet that is ground and washed in an alkali solution, acid solution and saturated oxalic acid solution respectively, then taking out and washing with a distilledwater to obtain a pre-treated metallic matrix of titanium; placing cathode titanium plates at two dies of the metallic matrix of titanium symmetrically and placing the both into a mixture of MnSO4 and H2SO4, then calcining after deposited by the anode electro-deposition process to obtain Ti/MnO2 electrode; the titanium plate cathode and the Ti/MnO2 electrode are placed in the mixture of Pb(No3)2,Cu(NO3)2, NaF and HNO3, then power is supplied by two stage during the anode electro-deposition process to obtain the Ti/MnO2/PbO2 composite electrode. The production method provided by the inventionis simple and the manufacturing cost is low; the metal oxide electrode produced by the invention can be used for the treatment of organic wastewater and is characterized by high activity, good conductivity, strong anodic oxidation resistance and long service life.
