摘　　要：随着染料工业的发展和印染加工技术的进步,染料结构的稳定性大为提高,给脱色处理增加了难度,为解决此难题,本研究以高盐度染色废水脱色回用为研究目标,采用高级芬顿氧化与臭氧氧化脱色、锰砂过滤除铁的工艺,处理后的水质色度可达回用水标准,水中的盐分含量基本不变,可在添加少量盐分的基础上满足生产回用要求。不仅解决了印染企业高盐度废水难处理的难题,还给高盐度废水回用提供了一套低成本、高效、稳定的解决途径。With the advances in the development of industrial dye and dyeing processing technology,the structural stability of the dye improves greatly,increasing the difficulty of bleaching treatment. To solve this problem,with bleaching and reusing of high salinity dyeing wastewater as research objectives,this study adopted the process of bleaching through advanced Fenton oxidation and ozonation and removing iron through manganese -sand filter. The treated water reached chroma standards of reused water,and the salt content in the water basically unchanged. The treated water can meet the requirements for production based on adding a small amount of salt. This study not only solve the intractable problem of high salinity wastewater for printing and dyeing enterprises,but also provide a low-cost,high-efficiency and stable way to resolve the reusing of high salinity wastewater.
