摘要
中国铬渣排放量大,仅依靠无害化效率评价,已经不能全面地表征铬渣的性质和填埋后铬渣的安全风险。文章从铬的价态和形态分析技术入手,分析目前铬渣处理和处置方法的优缺点,结合无害化处理后铬渣在填埋中的变化规律,得出铬渣在环境风险和生态学上的分析和评价方法。
emission of chromium slag is mass in china, assessment of harmless efficiency had not showed completely the character of chromium slag＇s property and safety risk of landfill chromium residue. The paper depend on chromium＇s chemical valence and fraction analysis, unite change rule of chromium slag which used harmless treatment landfill and receive chromium slag＇s analysis and evaluation method in environmental risk and ecology.
