还原造锍熔炼技术是可综合回收利用高铁、含铅固体废物的一种新技术。其主要副产物是炉渣和铁锍。采用浸出毒性实验、BCR三步连续浸提以及Hakanson潜在生态风险评价等方法系统地对还原造锍主要副产物和进炉炉料中重金属(Cd、Zn、Pb 和 As)的环境风险进行评价。结果表明,经过还原造锍熔炼后,水淬渣和铁锍中重金属潜在的环境生态风险明显比进炉炉料的低。
還原造锍鎔煉技術是可綜閤迴收利用高鐵、含鉛固體廢物的一種新技術。其主要副產物是爐渣和鐵锍。採用浸齣毒性實驗、BCR三步連續浸提以及Hakanson潛在生態風險評價等方法繫統地對還原造锍主要副產物和進爐爐料中重金屬(Cd、Zn、Pb 和 As)的環境風險進行評價。結果錶明,經過還原造锍鎔煉後,水淬渣和鐵锍中重金屬潛在的環境生態風險明顯比進爐爐料的低。

A new process for utilization of hazardous lead-bearing wastes and iron-rich wastes by reducing-matting smelting has been developed. The slag (SG) and the iron-rich matte (IRM) are the main by-products from reducing-matting smelting of lead-bearing wastes and iron-rich wastes. The environmental risk of heavy metals (Cd, Zn, Pb and As) in the main by-products versus the charging material for reducing-matting smelting (CM) has been systematically assessed using leaching toxicity test, the three-stage sequential extraction procedure of European Community Bureau of Reference (BCR) and Hakanson Potential Ecological Risk Index Method (PERI). The results demonstrate that the ecological risk level of heavy metals for SG and IRM is significantly reduced after the reducing-matting smelting process compared with that for CM.
