| Summary: | 碩士 === 淡江大學 === 水資源及環境工程所 === 83 === Organics from landfill leachate are complicated. After
decomposition, inorganic salt and organic by-product might
both be able to combine with Fe2+ to form chelate or to
compete with.OH. That will affect the result of Fenton
treatment. Hence, we conduct a study by using simple
organics probing into several objectives separately during the
process of Fenton treatment such as the impact of organic
decomposition while existing the inorganic salt and the
decomposing behavior of different organics by means of Fenton
treatment. Furthermore, we focus study on landfill leach to
explore the impact of inorganic salts to Fenton reaction.
CO32- 、 Cl- 、 NO2- are three dominate players to the
reaction process of Fenton treatment because they
influence greatly to the decomposition of organic. We evaluate
two fields by two methods of COD and TOC. In simple
organic system, existing inorganic salt to the impact of
organic through Fenton treatment as follows: by the evaluation
of COD，then NO2->CO32->Cl-> NO3- ≒ SO42- by the evaluation of
TOC, then CO32->Cl->NO2->SO42- NO3- In landfill leachate system
as follows: by the evaluation of COD,then Cl->NO2->CO32->SO42->
NO3- by the evaluation of TOC,then CO32->NO2->Cl->SO42->NO3-
