The invention relates to a method for degrading organic wastewater by coupling light field, electric field and thermal field by utilizing solar energy. According to the method, electric energy is provided by adopting a solar battery; thermal energy is provided by adopting a solar thermal collecting device; carbon nano-tubes/secondary anodized TiO2 nano-tubes are taken as a working electrode; a platinum electrode is taken as a counter electrode; the counter electrode is electrically conducted with the positive electrode of the solar battery; the counter electrode is electrically conducted withthe negative electrode of the solar battery; before degradation, the working electrode and the counter electrode are placed into organic wastewater; the organic wastewater is heated by utilizing the solar thermal collecting device, and then, stands in a dark environment without electricity; in degradation, the organic wastewater is heated by utilizing the solar thermal collecting device, the wastewater is electrified by u
