光合细菌对染料废水脱色的初步研究

Decoloriza tion of Dyeing Waste water Using Purple Nonsulfur Photosynthetie Bacteria

从山两纺织印染厂废水处理曝气池活性污泥中分离到脱色性能较好的紫色非硫光合细菌,分别对15种染料进行了脱色试验,在黑暗厌氧条件下对12种染料具有较好的脱色作用,脱色率均达75％以上,测验了温度、pH值等因素对脱色的影响并对脱色机理进行了初探。

The purple nonsulfur photosynthetic bacteria have-been separated from the activated sludge in an aeration tank at Shanxi Textile Mill. The bacteria were used to decolor 14 kinds of dyeing wasrewater, of which under anaerobic conditions 12 kinds of dyes were mostly decolored. The efficiency of decolorization was higher thzp 75%. The influence of temperature, pH, etc. on the decolourization and the decolourizing mechanism have also-been studied.
