摘要：通過(guò)單因素和正交試驗(yàn)確定了一種含少動(dòng)鞘氨醇單胞菌（Sphingomonas paucimobilis）的微生物絮凝劑對(duì)酸性媒介黑T染料的最佳脫色條件。結(jié)果表明該絮凝劑對(duì)酸性媒介黑T染料具有較好的絮凝脫色效果。添加高嶺土模擬工業(yè)酸性媒介黑T（1 000 mg/L）的廢水中，調(diào)整pH為4.0，絮凝液添加量為2%，CaCl2添加量為0.16%，酸性媒介黑T染料廢水的絮凝脫色率可達(dá)到95%。

Abstract： The previous study showed that the microbial flocculant contained Sphingomonas paucimobilis could discolor mordant black T dye wastewater efficiently. In this study， single factor tests and orthogonal tests were used to determine the optimized decolorization. The study demonstrated that the decolorization rate of mordant black T dye wastewater（1 000 mg/L） reached up to 95%， when pH was 4.0， the content of flocculation liquid was 2%， and that of CaCl2 was added to 0.16%.

Key words： microbial flocculant； dye wastewater； decolorization
