| titleOfInvention | Wastewater treatment method in metal surface treatment |
| abstract | An object of the present invention is to provide an efficient and low-cost wastewater treatment method in metal surface treatment. A wastewater treatment method in a metal surface treatment comprising a plurality of washing steps including at least one stage of washing with ion-exchanged water and at least one stage of ordinary washing, wherein the washing with ion-exchanged water is performed by washing with water. The generated waste water is introduced into an ion exchange device and regenerated, and the above-mentioned ordinary water washing is performed in a metal surface treatment in which the generated waste water is neutralized and then water is evaporated to be discarded as sludge. Wastewater treatment method. [Selection diagram] None |
