Abstract

The invention discloses an electroplating metal-washing wastewater treatment recovery device which comprises an external controller, at least one sewage treatment tank and a water pump connected with the sewage treatment tank. A metal carrier is arranged at the bottom in the sewage treatment tank, a concentration sensor is arranged on the side wall above the metal carrier, the water pump is arranged outside the sewage treatment tank, a water inlet of the water pump is connected with a water outlet of the sewage treatment tank, the concentration sensor acquires concentration of liquid in the sewage treatment tank and sends the concentration to the external controller in a wireless mode, the control end of the water pump is connected with the external controller, and the controller receives and processes concentration information acquired by the concentration sensor and controls switching of the water pump according to the concentration information. The electroplating metal-washing wastewater treatment recovery device enables sewage to be fully and effectively treated and avoids environment pollution. In addition, the metal carrier is adopted to absorb metal ions, metal in electroplating wastewater can be secondarily recycled, and energy is effectively saved.

Description

technical field [0001] The invention belongs to the field of electroplating cleaning devices, and in particular relates to a treatment and recovery device for electroplating cleaning metal wastewater. Background technique [0002] Currently known rinsing water cleaning devices for electroplated parts usually adopt continuous countercurrent rinsing in the form of local long flowing water in order to reduce water pollution on the automatic electroplating production line. [0003] There are mainly the following methods for electroplating wastewater treatment: [0004] Chemical method: At present, 80% of the electroplating cleaning wastewater treatment process adopts chemical method, but even if the electroplating wastewater is discharged up to the standard after chemical treatment, there are still heavy metals in it, which are easily absorbed and accumulated by animals and plants, and transferred to the in the human body. And the discharged water cannot be recycled, nor can i...
