The invention discloses a device and a method for processing restaurant wastewater. A ferrallitic sheet is used as an anode and a graphite sheet is used as a cathode to carry out pulse direct current electrolysis on the restaurant wastewater so as to cause an electrocoagulation reaction; simultaneously ultrafine ozone bubbles are fed into an electrocoagulation reaction region to strengthen the electrocoagulation reaction, so that ferrous irons Fe2+ generated in the electrolysis process is rapidly converted into ferric irons Fe3+, the volume of flocculate becomes larger and the flocculate precipitates more efficiently to remove most of pollutants in the wastewater; sludge generated in the electrocoagulation process enters an activated sludge reactor and a sludge concentrating and extruding device; and clear water containing a little amount of organic matter enters an aeration-ozone-ultraviolet combined treatment degradation tank and a photocatalyst micro filtration membrane, and finally outflows through a fine porous sand filtering tank. The produced water can reach the primary standard in the industry. The processing method has high impact-load resistance. The outlet water quality is stable. In the engineering, consumables have long service life. Therefore, the processing cost of the restaurant wastewater can be greatly reduced.
