铬渣处理方法研究现状

RESEARCH STATUS OF THE CHROMIUM RESIDUE TREATMENT

铬元素是现代工业最重要的原材料之一,但有钙焙烧工艺产生的铬渣会对环境和人体健康产生巨大的危害。介绍和分析了国内外铬渣处理处置的主要方法及其优缺点,国外集中于铬渣的无害化处理,而国内则以铬渣的综合利用为主。在越来越注重环境效益和资源利用率的今天,铬渣的综合利用更能获得经济效益和环境效益的双赢。

Although chromium is one of the most important raw material in modern industry,the chromium residue produced in the calcium-roasting does harm to people’s health and pollutes the ecological environment seriously. This paper introduced and analyzed the advantages and disadvantages of these main ways of chromium residue disposal at home and abroad. The treatment abroad focused on chromium slag disposal safely,but the treatment domestic is given priority to the comprehensive utilization of chromium slag. Nowadays,people pay more attention to the environment benefit and the resource utilization rate,so the comprehensive utilization of the chromium residue can get a ideal solution for both economic and environment benefit.
