[0002] With the development of science and technology, precious metal composite materials have gradually penetrated into people's household appliances and industrial production equipment. The recycling of precious metal secondary resources mainly relies on mature pyrometallurgical and hydrometallurgical processes, combined with traditional processes based on dissolution-precipitation (crystallization), and comprehensive use of solvent extraction, electrodeposition and solid phase extraction. Before the precious metals are recovered, they need to be cleaned to remove external adhering impurities, etc., and the direct discharge of these cleaning wastewaters to the outside world will cause environmental pollution. Therefore, the wastewater needs to be treated. For this purpose, we provide a wastewater treatment device for precious metal recovery production.
