Fe/Cu和Fe/Cu/C内电解处理亚甲基蓝模拟染料废水
|
摘要
采用Fe/Cu二元内电解和Fe/Cu/C三元内电解处理亚甲基蓝模拟染料废水,探讨了Fe/Cu和Fe/Cu/C质量比、填料投加量、废水初始pH、反应时间和反应温度对COD去除率的影响,优化了两种内电解的工艺条件,初步分析了二者高COD去除率的原因。试验结果表明,在试验条件下, Fe/Cu二元内电解和Fe/Cu/C三元内电解的COD去除率均在90%以上;相同条件下, Fe/Cu/C三元内电解COD去除率更高,反应时间更短,填料投加量更少。Fe/Cu和Fe/Cu/C内电解的优化工艺条件分别为:Fe/Cu质量比4∶5,填料投加量27 g/L,初始pH=6,反应时间8 h,反应温度20℃;Fe/Cu/C质量比4∶5∶1,填料投加量20 g/L,初始pH=6,反应时间12 h,反应温度20℃。Fe/Cu和Fe/Cu/C内电解高COD去除率的原因可能是:微米级填料提高了与污染物的接触面积,形成了更多的微原电池;填料具有一定的纳米铁的特性。
Fe/Cu binary and Fe/Cu/C ternary internal electrolysis systems were used to treat the dye wastewater simulated by methylene blue. The effect of mass ratios of Fe/Cu and Fe/Cu/C, filler dosage, initial pH values of wastewater, reaction time and reaction temperature on COD removal was discussed, and the optimum conditions of internal electrolysis were also determined. Meanwhile, the high COD removals were initially investigated. The test results showed that the COD removal rates of Fe/Cu binary and Fe/Cu/C ternary internal electrolysis systems were all greater than 90% in the test conditions. Compared with Fe/Cu binary internal electrolysis under the same conditions, the advantages of Fe/Cu/C ternary internal electrolysis were higher COD removal, shorter reaction time and less filler dosage. The optimum conditions of Fe/Cu binary and Fe/Cu/C ternary internal electrolysis systems were respectively as following: Fe/Cu mass ratio 4∶5, filler dosage 27 g/L, initial pH value 6, reaction time 8 h, reaction temperature 20 ℃; Fe/Cu/C mass ratio 4∶5∶1, filler dosage 20 g/L, initial pH value 6, reaction time 12 h, reaction temperature 20 ℃. The reason for the high COD removal rate of Fe/Cu and Fe/Cu/C internal electrolysis may be due to micron level fillers.In the contact area,the contaminants formed more microcells, their particles had a certain characteristics of nano iron.
