微电解-黄孢原毛平革菌对染料的脱色作用

Discolourization of Dye by Micro-electrolysis-P.C. Process

以微电解为预处理,黄孢原毛平革菌为后处理,进行单一染料(酸性品红、亚甲基蓝)和混合染料(酸性品红、亚甲基蓝、结晶紫、蕃红花红)废水的处理脱色研究,在微电解时间为10 min,pH=4.5,进水染料质量浓度为200 mg/L的条件下,酸性品红和亚甲基蓝脱色率分别达74.9%和80.7%。混合染料在微电解预处理的条件下,再经黄孢原毛平革菌处理后,1 d脱色率就达到80%,实验证明了微电解-黄孢原毛平革菌工艺联用的可行性。

Using micro-electrolysis as a pretreatment, and Phanerochaete chrysosporium （P. C） for the post-treatment, research on the decolorization of single dye （fuchsine acid and methylene blue） and mixed dye wastewater （fuchsine acid, methylene blue, Under the condition of microelectrolysis time 10 min, crystal violet and safranine T） was earried out. pH 4. 5 and influent concentration 200 mg/L, decoloration rate of fuchsine acid and methylene blue reached 74. 9% and 80. 7% respectively. With micro-electrolysis as a pretreatment,decolorization rate of mixed dye by P. C reached 80% in 1 d. The experimental result proved the feasibility of the micro-electrolysis - P. C process
