From the perspective of environmental protection and comprehensive utilization, most lead-zinc smelters are built with a two-to-two acid making system, so that the recovery of smoke dust and the sulfuric acid making from sulfur dioxide are realized. However, a large amount of strongly acidic wastewater containing heavy metals, namely, waste acid, is generated in the process. The waste acid contains toxic substances such as mercury, arsenic, cadmium and the like, and the content of the waste acid is higher than that of common industrial wastewater, so that the waste acid has great harm to the environment. Therefore, the method has certain importance and urgency for treating the heavy metal high-pollution acid.
