The invention realizes galvanization wasting water online recycle device of cleaning manufacturing. For a long time, people have researched many kinds of methods to reduce wasting water, but most of them cannot be popularized because of maneuverability or cost problems. The invention includes an electrode chamber that is made up of insulation box and metal plate in the box that is connected to positive electrode or negative electrode, and another metal plate connected to positive electrode or negative electrode. A hole used to pass through metal ion is set on the insulation box. And ion exchange film is covered on the surface of the hole. The invention has a good effect for galvanization wasting water. The recycled metal can be easily to use and need not send to smelt factory.
