乙炔清净次氯酸钠废水的回用

摘要

Technologies for the treatment of waste sodium hypochlorite solution from acetylene purification process were introduced .Through adopting such methods as vacuum extraction ,oxida-tion ,flocculation ,precipitation ,and filtration ,acetylene dissolved in the waste sodium hypochlo-rite solution was recovered ;the contained impurities ,such as chlorides ,silicon ,phosphorus ,and magnesium ,were removed ;thus ,the hidden danger existed in the preparation of sodium hypochlo-rite solution was reduced as well as the influences on the production and quality of cement .%介绍了乙炔清净工序产生的次氯酸钠废水的处理技术，通过采用真空萃取、氧化、絮凝、沉淀、过滤等方法，回收了次氯酸钠废水中溶解的乙炔，去除了其中的氯化物、硅、硫、磷、镁等杂质，减少了次氯酸钠配制的安全隐患和对电石渣水泥生产及质量的影响。
