摘　　要：研究了环己烷氧化废碱液硫酸酸化处理后所得酸化污水萃取、蒸发处理工艺。结果表明 ,用环己酮、环己醇作为萃取剂 ,在较佳萃取工艺条件下 ,COD去除率可达 75 %以上 ,污水COD值可从 80 0 0 0mg/L降至2 0 0 0 0mg/L以下。进一步对萃取过的酸化污水进行汽提、蒸发结晶 ,可回收得到较高质量的工业无水硫酸钠产品。综合确定了一种较佳的废碱液利用污水综合处理方案。Process of extraction and evaporation on waste neutralization water of saponification solution of cyclohexane oxidation were investigated. Under optimum process conditions, using cyclohexanone or cyclohexanol as extracting-agent, above 75% COD could be removed, the COD number of waste water dropped to 20?000?mg/L from 80?000?mg/L. Then waste neutralization water was distilled, vaporized and crystallized, and industrial crystal of sodium sulfate with high quality were obtained. An optimum process of treatment on waste neutralization water of saponification solution is established.
