| 摘 要： | 采用臭氧氧化法处理经反渗透膜处理后的浓缩垃圾渗滤液,并建立了氧化降解反应动力学模型.结果表明,氧化降解初始反应速率主要与初始pH、臭氧投量、反应温度和初始COD有关.在pH 8.0,温度30℃,臭氧投量5.02 g/h,反应时间90 min的条件下,反渗透浓缩渗滤液的COD去除率达到67.6%;并且在pH为2.0～8....

| Abstract: | This study kinetically investigated landfill leachate rejected by reverse osmosis(RO) oxidation degradation by ozonation. initial pH, ozone dosage, temperature and initial COD had significant impact on the oxidation rate. The results demonstrated that for the removal efficiencies of COD 67.6% under the conditions of 8.0 pH, 5.02 g/h ozone dosage, 303K temperature.The empirical kinetic equation of ozonation degradation for landfill leachate under the conditions of 2.0-8.0 pH, 2.53-6.90 g/h ozone dosage, 934-4037 mg/L initial COD, 283-323 K temperature fitted well with the experimental data(R2 0.969-0.996), with low activation energy Ea= 1.43×104 J·mol-1. |
