摘要
分析论述了钽铌冶金过程中的污染来源、污染形式、特点及危害,指出含氟化物、放射性、有机萃取剂的废渣、废水、废气是其主要污染物,并针对性地介绍了对这些污染物的治理措施。
Analysis and discussion is made on the source,type, nature and harm of the pollution from tantalum and niobium hydrometallurgy. Primary pollutants include waste residue,waste water,exhaust gas containing with fluoride,radioactive waste,organic extractant. Pollutant control measures are put forward.
