摘要:
针对难生物降解的实际高浓度兽药废水，实验考察了Fe/C微电解、O3氧化、Fe/C+H2O2氧化、Fe/C+O3氧化和Fe/C+H2O2+O3组合氧化工艺对兽药废水的处理效果. 实验结果表明：Fe/C最佳反应时间为2 h，O3的最佳反应时间为3 h，O3反应前废水最佳pH为9，H2O2的最佳投加量为6 mL/L. 最佳条件下，Fe/C对废水COD的去除率为21.71%，Fe/C+H2O2工艺为42.76%，Fe/C+H2O2+O3组合工艺为57.24%. 优化可知，Fe/C+H2O2+O3组合工艺可有效氧化实际兽药废水，废水COD的大幅下降为后续的生物处理奠定了基础.
Abstract:
For real biorefractory veterinary medicine wastewater with high concentration, the oxidative effects of Fe/C micro-electrolysis,O3 oxidation, Fe/C+O3, Fe/C+H2O2 and Fe/C+H2O2+O3 different processes were evaluated for the pretreatment of veterinary wastewater. The experimental results demonstrated that the optimum reaction time for Fe/C was 2 h, 3 h of reaction time and pH 9 of initial wastewater were optimized for O3 oxidation, and optimal H2O2 dosage was 6 mL/L. Under the optimal conditions, the COD removal rates of veterinary wastewater reached 21.71%, 42.76% and 57.24% for Fe/C, Fe/C+H2O2 and Fe/C+H2O2+O3 processes respectively. The optimization of the process indicated that Fe/C+H2O2+O3 combined process could oxidize the veterinary wastewater effectively, and a sharp decrease of COD value was beneficial to further biological treatment.
