Study on the Treatment of Color by Fly Ash

The fly ash is the vice- outcome of the coal combustion, it results pollution of the environment. The possibility of the fly ash removing color in water was studied in this text. Through experiment text of removal color in methylic orange waste water by front and back character modified of the fly ash, the mechanism was discussed. The influent density of dosing quantity, respond time, respond temperature, influent density and the pH effect agent to the decolorize experiment was considered. The best testing was recommend, the result is that: influent density: 3 mg/ L, dosing quantity: 36 g/L, respond time: 20 min, respond temperature : 20~30°C, pH: 6~8. The rate of decolor was 98.6%. A new path for the comprehensive exploitation of the fly ash was developed.
