- Abstract
- This paper reported the visible light decoloration rate of the solution, mixed methylene blue with the lixivium obtained in removing iron from quartz sand by ultrasonic treatment. The effect of the concentration of ethanedionic acid, time of treatment by ultrasound, the initial concentration of methylene blue and the volume of lixivium were investigated in details. The primary result showed that it was apparent improved in decoloration efficiency after mixed. And the decoloration rate improved more highly after visible light irradiation. The decoloration rate of mixed solution containing 20 ppm methylene blue got to 99.5% under the condition of c[H2C2O4] 5g/L, treating by ultrasonic for 2.5h, using 30mL lixivium. It also had certain affection for the CODCr of lixivium. This process realized the multipurpose utilization of liquid waste.
