  • 摘要: 采用芬顿法、光催化氧化法与生物降解法相结合，研究对乙酰氨基酚制备过程中高浓度废水的降解。以COD 的去除率为指标，研究各种方法的主要因素对废水降解效果的影响，通过控制单因素变量实验， 确定各种方法的最佳工艺条件。结果表明，芬顿法的最佳工艺条件：废水的pH为4.0、 FeSO4·7H2O加入量为0.10 mol/L、 H2O2（30%）加入量为56.5 mL/L、反应时间3 h；光催化氧化降解废水的最佳条件：H2O2（30%）加入量4.5 mL/L，光照时间4 h。生物降解较适宜条件：pH为7.0，温度为28~29℃。在各种方法的最佳条件下，可使废水的COD从18 979.24 mg/L降至36.14 mg/L。
    Abstract: The degradation of high concentration wastewater from acetaminophen manufacturing process was studied by combined Fenton oxidation, photocatalytic oxidation and biodegradation methods. In this experiment research,the influences of main parameters on wastewater degradation were studied,and the COD removal was used as evaluating indicator. The optimal operating conditions determined by experiments of controlling single factor variables. The result showed that the optimal operating conditions of experimental processes are as follows:for Fenton oxidation,the wastewater pH of 4.0, FeSO4·7H2O dosage of 0.10 mol/L, H2O2(30%)dosage of 56.5 mL/L,the reaction time of 3 h; for photocatalytic oxidation, H2O2(30%)dosage of 4.5 mL/L,the reaction time of 4 h;for biodegradation process, the wastewater pH of 7.0,the temperature of 28~29℃. The COD declined from 18 979.24 mg/L to 36.14 mg/L under optimal conditions.
