The present invention relates to the technical field of water treatment, in particular to a recycling method and device of industrial wastewater including the following steps that the industrial wastewater is intensively storaged; pollutants of heavy metal and oil are separated by electrolyzing; the mud is separated by centrifugal subsidence; the purified water and sewage are separated by filtrating and purifying and discharged respectively; the purified water is conducted in a process water system while the sewage enters recycling and purifying again. The present invention can completely separate the pollutants in the industrial wastewater discharged by the industries of paper making, dyeing and finishing, leather and galvanization, recycle heavy metal materials and product environment protection mud and particularly that the water resource can be recycled. The present invention has greatly reduced resource waste and can be helpful to realize the zero discharge of industrial wastewater, thereby lightening pollutions on environment and formed a typical concept mode of modern industrial production.
