- Abstract:
- Fe/Al/C multiple micro?electrolysis and H2O2 process was applied in pesticide wastewater treatment. The operation parameters were determined by intermittent experiment, and performance of the process for pesticide production wastewater treatment was the best under the following conditions: the initial pH was 4, dosages of Na2SO4 and H2O2 were 0.03 mol/L and 1.5 mL/L and the reaction time was 80 min. The performance of the process for pesticide production wastewater treatment under continuous operation was explored. The average COD removal efficiency was 88.5%, the average biological toxicity reduction rate was 63.7%, and the average B/C ratio was increased from 0.126 to 0.341. The degradation process of pesticide production wastewater by Fe/Al/C multiple micro?electrolysis and H2O2 process conformed to first?order kinetic reaction, and the rate constant kCOD and correlation coefficient R2 were 0.018 8 min-1 and 0.989 8, respectively. After the treatment of pesticide production wastewater by Fe/Al/C multiple micro?electrolysis and H2O2 process, the UV-Vis spectral intensity of organic groups was significantly reduced, indicating that the organic compounds were effectively degraded.
