【摘要】 本文研究了活化作用、颗粒活性炭的加入对亚甲蓝降解的影响。通过正交试验,综合考虑能耗及其他因素,显示在曝气量为15L/h、停留时间45min、pH为3、温度25℃时色度去除率较高,达97%以上。运用电子自旋共振仪证明了自由基的存在,说明降解过程属高级氧化过程。更多还原

【Abstract】 The effects of adding GAC and activation of iron powder on the treatment of methylene blue were studied. By orthogonal experiment and energy-cost analysis, results showed that the aeration quantity, retention time, pH value and temperature were 15L/h,45min,3,25℃, respectively. The color removal was over 97%. The existence of radicals, which implied an advanced oxidation process, was proved by ESR.更多还原
