Abstract

With the increase in the use of electronic products, the consumption of circuit boards also increased sharply, the amount of waste liquid discharged in the process of producing circuit boards will follow the increase, and these waste liquids, if discharged directly, not only cause a great waste of resources, but also cause serious water pollution, soil pollution, and thus with the food chain into the body of people and animals, seriously endangering human health, so we need to Therefore, we need to recycle and utilize this resource. In this paper, we adopt the recycling treatment system to transport the waste solution from the production line to the electrolyzer, and the overflow tank stores the electrolyte discharged from the production line. We adopt the waste electrolyte after treating the micro-etching waste solution for waste solution recycling treatment, and electrolyze the micro-etching waste solution again after treatment, and use it repeatedly to improve the utilization rate of electrolyte.
