NOVELTY - Processing solar thermal-electrochemical coupling treatment of oily sewage comprises using the photo-thermal effect of solar energy to provide thermal energy, and the photo-electric effect to provide electrical energy, and carrying out constant current electrolysis on the oily sewage in an electrolytic cell with a cathode and an anode, where the temperature of the electrolytic cell is 20-90degreesC, and the current of the constant-current electrolysis is 50-90 mA. USE - The method is useful for processing solar thermal-electrochemical coupling treatment of oily sewage, which is useful in oil field development and ecological environment protection. ADVANTAGE - The method: utilizes solar energy as green energy, solar electrochemical, photo-catalysis and solar heat synergy; further optimizes the reaction path of oil-containing sewage in oil field on the basis of improving the solar utilization rate; saves energy; greatly improves the degradation efficiency of oil containing waste water in the oil field; breaks the limitation of the traditional photovoltaic method for solar light utilization; really reaches the purpose of environment-friendly; provides a new direction efficient treatment of industrial organic waste water; further adjusts heat field and electric field by using highly ordered and vertically arranged titanium dioxide nano-tube; and more stably and efficiently degrades oil in oily sewage by means of titanium dioxide nanotube of photo catalytic activity and good corrosion resistance.
