Decolonization Experiments of Microbial Flocculant in the Dye Wastewater

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%.
