摘要:
针对复合污染原水中锰和天然有机物的同步去除问题，研究了亚铁/过氧单硫酸盐（Fe2+/PMS）体系的去除途径和效果。结果表明：在复合污染条件下，当原水中Mn2+由0增加至1.0 mg/L时，Fe2+/PMS体系对DOC和UV254的去除率分别提高了7.39%和3.58%，而出水锰浓度为0.01~0.79 μg/L，表明Fe2+/PMS体系可以同步去除复合污染原水中的锰和天然有机物。机理分析表明，Mn2+的存在促进了Fe2+/Fe3+循环，强化自由基产生的同时促进了Fe3+的生成，且其氧化产物MnO2具有较好的助凝作用。动力学分析表明，Mn2+对Fe2+/PMS体系的强化作用主要在慢速反应阶段，提高了对有机物的去除效果。
Abstract:
To achieve simultaneous removal of manganese and natural organic matter from combined polluted raw water, the removal pathway and performance of ferrous/peroxymonosulfate (Fe2+/PMS) system were investigated. When the Mn2+ concentration in combined polluted raw water increased from 0 to 1.0 mg/L, the removal rates of DOC and UV254 in the Fe2+/PMS system increased by 7.39% and 3.58%, respectively, and the manganese concentration in effluent ranged from 0.01 μg/L to 0.79 μg/L, indicating that the system could be used for simultaneous removal of manganese and natural organic matter from combined polluted raw water. The mechanism analysis showed that the presence of Mn2+ promoted the Fe2+/Fe3+ cycle, enhanced the formation of free radicals and promoted the formation of Fe3+, and its oxidation product MnO2 had a good coagulation performance. The kinetic analysis showed that Mn2+ enhanced the coagulation of Fe2+/PMS system mainly at the slow reaction stage, thus improved the removal efficiency of organic matter.
