Efficient electro-deposited heavy metal cleaning system

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present invention, and to make the above-mentioned objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the structural diagram.

[0026] The structure diagram of a high-efficiency electrodeposition heavy metal cleaning system engineering example is as follows figure 2 As shown, the workshop tail water first passes through the filter membrane at the front end of the reaction tank. The filter membrane is one or a combination of microfiltration membrane, ultrafiltration membrane, and reverse osmosis membrane according to the composition of the tail water. After the tail water is filtered, the heavy metal ions are reduced by electrons when they pass through the high-efficiency heavy metal electrodeposition film, forming heavy metal crystals and uniformly deposited on the high-efficiency heavy metal electrodeposition film. The pH value detection and adjustment sensor integrated inside the high-efficiency heavy metal electrodeposition film adjusts the pH value of the water and the overpotential adjustment sensor adjusts the overpotential. The two work together to achieve the best conditions for heavy metal electrodeposition; at the same time, it can be based on heavy metals. The number of ion species and recycling requirements configure the number of high-efficiency heavy metal electrodeposition films, and use the principle of different overpotentials required for the reduction of different types of heavy metal ions to deposit the same types of heavy metals on the same high-efficiency heavy metal electrodeposition film. The treated water is filtered through a filter membrane for further purification, and then sent to the electroplating workshop through a transfer pump for recycling.
