液态氰化物泄漏事故洗消方法的选择

Decontamination Method Selection of Liquid Cyanide Leakage Accidents

对几种常用的液态氰化物洗消方法如碱性氯化法、二氧化氯法、臭氧氧化法、硫酸亚铁法、高铁酸钾法、多硫化物法、活性炭吸附法进行了综述,探讨其优缺点及应用范围。通过分析认为,目前消防部队处置液态氰化物泄漏事故中所常用的碱性氯化法存在诸多不足,固态二氧化氯法、臭氧氧化法、硫酸亚铁法和多硫化物法可作为液态氰化物洗消备选方案,高铁酸钾法和活性炭吸附法可应用于经处理后废水的进一步处理。

This paper provides a comprehensive review of liquid cyanide decontamination methods such as chlorina-tion ,chlorine dioxide , ozone oxidization , ferrous sulfate , potassium ferrate , polysulfide and activated carbon , and analyzes the limitations and application ranges of these methods. The results showthat chloby fire departments has some disadvantages. Solid chlorine dioxide , ozone oxidization , fee＇ous sulfate and polysulfide can be the potential liquid cyanide decontamination method for cyanide leakage accidents , while potassium ferrateand activated carbon can be used in lowly concentrated cyanide containing wastewater.
