摘要: 采用光照生物膜体系的方法, 考察3种不同抑制作用的生物活性抑制剂对自然水体生物膜/水模拟体系中生物膜产生过氧化氢(H2O2)以及典型有机污染物十二烷基苯磺酸钠(SDBS)降解的影响. 结果表明: 光合作用抑制剂和呼吸作用抑制剂对H2O2生成和SDBS降解有显著的抑制作用, 二者的抑制效果几乎相同; 光呼吸作用抑制剂对H2O2生成和SDBS降解影响较小. 即生物的光合作用是H2O2等活性氧成分产生和有机污染物降解的主要原因, 其他生理作用的贡献相对较小.

Abstract:

By using the method of light irradiation in the biofilm system, we investigated three kinds of bioactivity inhibitors with different inhibitory effect on generation of H2O2 and degradation of typical organic pollutants of sodium dodecyl benzene sulfonate (SDBS) in natural biofilm/water simulation systems. The results show that inhibitors of photosynthesis and respiration have a significant inhibitory effect on the generation of H2O2 and degradation of SDBS, and the inhibitory effects of both of them are almost the same. The photo expiration inhibitor has little or no effect on the generation of H2O2 and degradation of SDBS. Therefore, the biological photosynthesis is the main reason for the generation of H2O2 and other reactive oxygen species, as well as the degradation of organic pollutants. Whereas, the contribution of other physiological role is relatively small.

Key words: sodium dodecyl benzene sulfonate (SDBS), biofilm, visible light, bioactivity inhibitor
