摘要:采用O_3/H_2O_2高级氧化工艺深度处理胞苷酸企业二级生化出水,考察了pH、H_2O_2用量、O_3浓度、反应时间等因素对深度处理效果的影响,探讨了有机磷矿化反应的动力学。结果表明,当废水有机磷质量浓度约为56 mg/L,COD约为640 mg/L时,适宜的反应条件为:pH 8.5,H_2O_2投加量20 mmol/L,O_3质量浓度12 mg/L,反应时间90 min;有机磷矿化反应遵循表观一级动力学,动力学常数为0.024 7 min-1。优化条件下,有机磷矿化率和COD去除率分别为91.6%和56.8%。O_3/H_2O_2氧化出水经混凝沉淀处理后,TP和COD符合纳管排放要求。
The O3/H2O2 process has been applied to the advanced treatment of the secondary biochemical effluent in a cytidine 5’-monophosphate(CMP)production plant,the influence of pH,H2O2 dosage,O3 concentration,reaction time on the advanced treatment process effects investigated,and the kinetics of organophosphorus mineralization re-action discussed.The results show that when the organophosphorous mass concentration of the wastewater is about 56 mg/L and COD about 640 mg/L,the optimum reaction conditions are as follows:pH is 8.5,H2O2 dosage 20 mmol/L,O3 mass concentration 12 mg/L and reaction time 90 min.The organophosphorus mineralization reaction follows the apparent-first-order kinetics,whose kinetic constant is 0.024 7 min-1.Under optimized conditions,the organophosph-orus mineralization rate and COD removing rate of the secondary effluent are about 91.6%and 56.8%,respectively.After the effluent of O3/H2O2 oxidation has been treated through coagulation and sedimentation process,the final eff-luent TP and COD can meet canal discharge requirements.
