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 O_3/H_2O_2 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,H_2O_2 dosage,O_3 concentration,reaction time on the advanced treatment process effects investigated,and the kinetics of organophosphorus mineralization reaction discussed. The results show that when the organophosphorous mass concentration of the wastewater is about56 mg/L and COD about 640 mg/L,the optimum reaction conditions are as follows:pH is 8.5,H_2O_2 dosage 20 mmol/L,O_3 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 organophosphorus mineralization rate and COD removing rate of the secondary effluent are about 91.6% and 56.8%,respectively.After the effluent of O_3/H_2O_2 oxidation has been treated through coagulation and sedimentation process,the final effluent TP and COD can meet canal discharge requirements.
