By using wastewater, of which the COD content is 500-1000 mg/L, the ammonia nitrogen content is 50-200 mg/L, the pH value is 6-9 and the chroma is 50-500, as an electrolyte, the wastewater flows into an electrolytic bath from the water inlet, flows through all tank units of the electrolytic bath in a plug-flow mode, and performs electrolytic reaction under the conditions that the current density is 5-15 mA/cm<2> and the hydraulic retention time is 30-120 minutes, thereby achieving the goals of electrocatalytic oxidation and wastewater COD and ammonia nitrogen removal at the same time. The titanium-base lead peroxide composite electrode plate is utilized to carry out the electrolytic catalytic oxidation reaction, thereby implementing synchronously oxidizing wastewater COD and ammonia nitrogen; and no chemical or biological reagent is needed in the reaction process, the wastewater retention time is short, the pollutant oxidation is thorough, no precipitate or sludge is generated, and the efficiency is high.

In a mechanical press, the pressure (cylinder force) of a hydraulic pressure chamber of a cylinder-piston mechanism provided in a slide of the mechanical press can be variably controlled with a high responsiveness by a hydraulic pump/motor driven by an electric servomotor, in response to a cylinder force command corresponding to the press load command. Accordingly, even if a die height value is set to a value small enough to cause an overload, the press load can be restricted before the occurrence of the overload, and this can save the trouble of strictly adjusting the die height value. Further, pressure-application time in the vicinity of a bottom dead center can be lengthened, and a breakthrough phenomenon can be suppressed from occurring at the end of pressure application. Still further, because the overload does not occur, pressure oil is not relieved, so that the interruption of a press operation is avoided.
