摘　　要：通过向进水中投加不同浓度的阴离子表面活性剂(LAS),研究了一体式平板膜生物反应器对高浓度LAS的去除性能。实验结果表明,当LAS投加量分别为15、25、35mg/L时,系统对LAS的平均去除率分别为97.73%、95.16%、91.49%,生物降解对LAS及COD的去除起到了主要作用。The performance of a plate membrane bioreactor for treating high concentration of anionic surfactant (LAS) was investigated in laboratory scale by changing the content of LAS in influent. The results showed that the average removal efficiency to LAS with the concentration of 15mg/L, 25mg/L and 35mg/L was 97.73%, 95.16% and 91.49% respectively. The removal efficiency of COD was in the range from 88.77% to 98.90%. It seemed that most LAS and COD were biodegradable.
