摘　　要：文章主要介绍了传统的铬盐泥处理技术及原理,并对解毒方法存在的问题进行分析。It was mainly introduced the removal of calcium,magnesium and sulfate ions of raw salt in the production process,which needed to add sodium hydroxide,sodium carbonate,calcium chloride to precipitate in the system. Sodium dichromate formed calcium chromate precipitate out of the system with the formation of ＂ chromium salt mud＂,because the chromium salt mud was hazardous waste,serious environmental pollution,chromium salt sludge generation control and effective treatment has become acid sodium production main work. Recently,several existing traditional detoxification process has been investigated summary and analyzed of the existing problems.
