ABSTRACT
White rot fungi is a kind of effective filamentous fungi which has a good effect on the decolorization for dye wastewater. This experiment makes a comparation with the decolorization ratio of three kinds of dye wastewater, such as direct sunproof yellow, scarlet and light-green. The results showed that white rot fungi has a great effects on the color of light-green under standing conditions, its decolorization rate is 70.6%; the second is yellow which reaches 58.3%, however, the decolorizing effect of scarlet is the worst, only 36.2%. So, the direct sunproof scarlet are treated under the conditions of adding straw and vibration, respectively. The results showed that the color removal rates of direct fast scarlet dye is greatly improved by adding straw which increases from 36.2-69.6%, while violent vibration does not significantly improve its decolorization. Similarly, adding straw can also improve the removal efficiency of direct sunproof light green and yellow and their decolorization rate increases to 92.2 and 83.8%, respectively, which improves by 21.6 and 25.4% than that of under stable condition.
