Abstract
This paper briefly describes the source and harm of cyanide containing wastewater, introduces the main treatment processes of cyanide containing wastewater, such as sulfur oxide air method, dioxygen water method, alkaline chlorination method, adsorption method, membrane separation method, and analyzes the applicability of various processes. The comprehensive recovery methods of valuable elements in cyanide containing wastewater in recent years are summarized and prospected, and the viewpoint of comprehensive recovery of valuable elements in cyanide containing wastewater on the basis of purification is obtained. The analysis results show that the purification of cyanide containing wastewater is conducive to the leaching of gold, and the comprehensive recovery of valuable elements can improve the economic benefits of enterprises.
