摘　　要：通过模拟实验,考察加入离子态、配合态和氧化物态的铁或锰对可见光照条件下自然水体生物膜体系中产生H_2O_2及十二烷基苯磺酸钠(SDBS)降解的影响,并分析体系中SDBS的降解机制.结果表明:加入不同形态的铁或锰均能促进体系中SDBS的降解,体系中H_2O_2的浓度呈先减小再增大的趋势;不同形态铁或锰的影响差异较小,其中离子态的作用相对较强,氧化物态的作用相对较弱;添加铁比添加锰的影响更明显.We investigated the effects of adding ionic state,complex state and oxidation state of iron or manganese on generation of H_2O_2 and degradation of sodium dodecyl benzene sulfonate（SDBS）in natural water biofilm systems under illumination via the simulation experiment,and analyzed the mechanism of degradation of SDBS in the system.The results indicate that different forms of iron or manganese can promote degradation of SDBS in the system,and the concentration of H_2O_2 decreases firstly and then increases in the system.Effects of different forms of iron or manganese are small.The effect of ionic state is relatively strong,and the effect of oxidation state is relatively week.The effect of adding iron is more obvious than that of adding manganese.
