The Influence of Ph Value on the Treatment of Direct Sun-Proof Dyes Wastewater by Iron Trichloride

Abstract:

The treatment of dyeing wastewater is a problem of great difficulty and a focus of public owing to its high color intensity, varying water quality and poor biodegradability. The optimal pH values of iron trichloride in treating three kinds of direct sun-proof dyeing wastewater were studied. Experimental results show when the concentration of iron trichloride was 2g/L, the optimum pH value were 8,6 and 7 for three kinds of simulated dye wastewater of direct sun-proof light green, yellow and scarlet.Under these conditions, the removal rate of turbidity were 88.7%, 89.5% and 92.9%, and the removal rate of color were 83.6%, 62.3% and 79.6%.
