摘　　要：本文介绍了影响浊度变化的重要因素—— Fe2 +和 STPP,进而讨论了浊度变化对 L AS降解的影响 ;以及不同 H2 O2 投加方式对 L AS降解的影响。研究表明 ,反应液的浊度值随 Fe2 +浓度的增加而增大 ,随 STPP浓度的增加而减小。且浊度越大 ,L AS的降解率越小。但不同H2 O2 投加方式对This paper introduced the main factor affected the change of trubidity-Fe 2+ and STPP,and discussed the effect on the degradation of LAS for the change of turbidity.Finally,the effect of different adding way of H 2O 2 on the removol rate of LAS was discussed. The results showed that the turbidity increased with the Fe 2+ concentration increase ,and decreased with the STPP concentration increase.And,the more the tribidity was,the less the removal rate of LAS was. But,the effect of different adding way of H 2O 2 on the removal rate of LAS was not evident.
