摘　　要：目前生物法处理高含盐染料废水的研究鲜有报道,实验对3种不同来源的活性污泥进行耐盐驯化,耐盐程度达到25%NaC l(w/w),用驯化得到的耐盐菌对高含盐染料K-2BP模拟废水进行厌氧脱色研究,脱色率达100%,并对其脱色机理进行了初步探讨,同时,进行了耐盐菌的脱色广谱性实验,结果表明驯化耐盐菌对所选取的13种不同结构的染料均有很高的脱色效果。研究为常规生物法应用于高含盐废水的处理提供了实验基础和理论依据。Three salt-tolerant mixed cultures were acclimatized by the gradually increasing NaCI concentration and these acclimatized cultures decolorized the simulated dye wastewater with high salt concentration （15% NaC1,w/w）. The results of this study suggested that different activated sludges could tolerate the concentration of 25% NaC1 by the acclimatized procedure and decolorize the simulated dye wastewater with high salt concentration in anaerobic conditions. It was demonstrated that the dye wastewater with high salt could be treated by activated sludge.
