The invention provides a method and a device for realize on-line recycle of electroplating rinse water, relates to a method and a device for electroplating wastewater treatment. The method adopts a stuffing evaporator as an evaporation concentration device for an electroplating solution, utilizes the device to efficiently evaporate and concentrate the electroplating solution on line during circulation and filtration of the electroplating solution, and directly supplements and recycles the electroplating rinse water to make the liquid level of the electroplating solution stabilized to a certain level and realize the on-line recycle of the electroplating rinse water as well as realize normal electroplating production at the same time. The device is arranged above an electroplating bath, and consists of the stuffing evaporator and an exhaust fan; the stuffing evaporator comprises a pressure plate, a stuffing, a support frame body, a grid plate and a sprayer; the support frame body is of a frame body, the top and the periphery of the support frame body are sealed, the bottom of the support frame body is opened, and the top of the support frame body is provided with an air extractor connector and an electroplating solution inlet pipe; the grid plate is fixed on the bottom of the support frame body, the stuffing is placed above the grid plate, the pressure plate is additionally arranged on the stuffing, the sprayer is fixed on the top of the support frame body, and a water inlet of the sprayer is connected with a filter in the electroplating device; and the exhaust fan is connected with the air extractor connector on the top of the support frame body.
