摘　　要：文章设计了一种环保型制备氧化铬绿的工艺——氢氧化铬热分解制备氧化铬绿,其中氢氧化铬可由含铬废水处理而得,再进行加热、煅烧、过滤等处理获得产品氧化铬绿,实现了废物利用。此外,对主要生产设备窑炉进行选型,并测定了滤渣中的六价铬含量,对比了进水与出水中的六价铬含量,结果表明出水中六价铬含量符合国家安全排放标准,体现了此工艺设计的环保性。This article designs an environmentally friendly process for preparing chromium oxide green:chromium hydroxide is thermally decomposed to prepare chromium oxide green.Chro⁃mium hydroxide can be obtained by treating wastewater containing chromium,and then subjected to heating,calcination,and filtration to obtain the product chromium oxide green,achieving waste utilization.This article selects the main production equipment and determines the hexavalent chro⁃mium content in the filter residue.The hexavalent chromium content in the inlet and outlet water is compared,and the hexavalent chromium content in the outlet water meets the national safety dis⁃charge standards,reflecting the environmental protection of this process design.
