摘要:
针对氢氧化铬粉末在烧结过程中会产生六价铬，直接填埋处理会对环境产生潜在的危害。采用在烧结过程中加入还原剂，以降低Cr2O3废渣中六价铬含量。研究结果表明，一次烧结前加入还原剂的处理方法，不能使烧结产品中的六价铬含量降到理想水平。在一次烧结后，再加入还原剂进行二次烧结的处理方法，可将六价铬含量降到较低的水平，对氢氧化铬烧结的环保处理过程有重要的指导意义。
Abstract:
Chromium hydroxide powder will produce hexavalent chromium during the sintering process, which direct landfill disposal may pose potential hazards to the environment. This article uses the addition of reducing agents during the sintering process to reduce the hexavalent chromium content in Cr2O3 waste residue. The research results indicate that the treatment method of adding a reducing agent before sintering cannot reduce the hexavalent chromium content in the sintered product to the ideal level. The method of adding a reducing agent for secondary sintering after a single sintering can reduce the hexavalent chromium content to a very low level,it has important guiding significance for the environmentally friendly treatment process of chromium hydroxide sintering.
