摘要:本研究采用氧化-吸附耦合工艺处理经生化处理后的制浆造纸混合废水，探讨了H2SO4、H2O2、FeSO4、Fenton辅助药剂对COD去除率和运行成本的影响，并采用响应面法进一步分析了反应体系的最优运行参数。结果表明，各因素对此反应体系的处理效果影响程度排序为：FeSO4>H2SO4≈Fenton辅助药剂>H2O2。当进水CODCr为(310±13) mg/L时，最优反应条件为：FeSO4投加量7.4 mL/L，H2O2（质量分数27.5%）投加量0.17 mL/L，H2SO4（3 mol/L）投加量2.0 mL/L，阳离子聚丙烯酰胺（CPAM）投加量4 mg/L，Fenton辅助药剂投加量0.245 mL/L，模型预测出水CODCr值为30 mg/L，验证实验的平均出水CODCr为42 mg/L，符合GB 3544—2008《制浆造纸工业水污染物排放标准》中直接排放标准的要求，吨水运行费用下降约14%。
Abstract:In this study， a synchronized oxidation-adsorption process was used to treat the mixed wastewater of pulping and paper making wastewater after biochemical treatment. The effects of H2SO4， H2O2， FeSO4 and Fenton adjuvant on removal of COD and operating cost were investigated. The optimal operating parameters of the process were further explored by Response Surface Methodology (RSM). The results showed that the order of influence of various factors on the treatment efficiency was FeSO4>H2SO4≈Fenton adjuvant>H2O2. The optimal reaction condition was that the dosage of FeSO4 was 7.4 mL/L， the dosage of H2O2 (mass fraction 27.5%) was 0.17 mL/L， the dosage of H2SO4 (3 mol/L) was 2.0 mL/L， the dosage of CPAM was 4 mg/L and the dosage of Fenton adjuvant was 0.245 mL/L. The effluent CODCr predicted by the model was 30 mg/L， while the average effluent CODCr of the verification experiment was 42 mg/L， which was satisfied to the standard GB3544—2008 Discharge Standard of Water Pollutants for Pulp and Paper Industry. The overall operating cost per ton of water had decreased by approximately 14%.
