摘要
有色冶炼污酸通常为高砷污酸,在污酸除砷的过程中会产生大量含砷危废渣,给企业以及环境造成巨大压力。在有效去除污酸中的砷的同时,减少危废渣的产生及其固化/稳定化、资源化是目前研究的重点,这对企业运行以及环境保护具有重要意义。本文讨论了在有色冶炼污酸中除砷的主要方法,同时对含砷渣的处置进行了相关的分析,旨在为从事该行业的相关工作者以及企业可以更好地处理含砷污酸和含砷危废渣。
Nonferrous smelting acid wastewater is usually high arsenic acid wastewater. In the process of removing arsenic from acid wastewater, a large amount of arsenic-containing hazardous waste residue will be produced, which will cause great pressure on enterprises and the environment. While effectively removing arsenic from acid wastewater, reducing the generation of hazardous waste residue and its solidification/stabilization and recycling are the focus of current research, which is of great significance to enterprise operation and environmental protection. This paper discusses the main methods of removing arsenic from nonferrous smelting waste acid, and analyzes the disposal of arsenic-containing slag, in order to better deal with arsenic-containing acid wastewater and arsenic-containing hazardous waste slag for relevant workers and enterprises engaged in this industry.
