Experimental Study of Photosynthetic Bacterial Degradation of Direct Red 4BS Wastewater

Abstract:

The photosynthetic bacteria direct red 4BS solution pH, light intensity, inoculum size, the concentration of sodium acetate, and the initial concentration of direct red 4BS degradation rate. The results show that: the initial concentration of 80 mg / L, the inoculation amount of 25% (v / v), pH 8.0, the light intensity 3000lx, sodium acetate, 1.6mg / L under the conditions, after 96 hours of direct red 4BS degradation rate up to 87.5%. Sodium acetate in the reaction can increase the degradation rate, experiments show that: the process of degradation of sodium acetate and direct red 4BS ratio of 20: 1 (m / m) the degradation rate is better. Direct Red 4BS low concentrations, the reaction kinetics of the degradation reaction are first-order kinetics.
