摘　　要：改造前,鳌合树脂塔再生酸性废水脱氣后回用至化盐工序,Ca^(2+)、Mg^(2+)等杂质不断积累.影响了盐水质量。介绍了将该酸性废水回用到三氯异氰尿酸生产装置的母液吹除工序的思路,并分析了改造效果。The acid wastewater formed in the regeneration of chelating resin tower was dechlorinated and reused to the dissolving salt process before transformation.Ca^(2+),Mg^(2+)and other impurities accumulated continuously and affected the quality of brine.The idea of recycling the acid wastewater to the mother liquor blowing-out process in a trichloroisocyanuric acid production unit was introduced.The transformation effect was analyzed.
