摘要:
在两种不同Fe2+浓度和6种双氧水投加浓度的Fenton条件下,对5种原油污染土壤进行了氧化实验.结果表明,投加225 mmol/L低浓度双氧水可促进土壤中短链烃C11 - C20的氧化去除,Total Petroleum Hydrocarbon(TPH)的氧化率高达38%.这是由于在低浓度双氧水(150～225 mmol/L)条件下H2O2分解时间长且产氧率低,从而能产生高强度的·OH,此时,短链烃C11 - C20的解析与氧化达到平衡,因而能被大量氧化去除.而高双氧水投加浓度(300～900 mmol/L)条件下,H2O2分解时间短且产氧率高,仅能产生低强度·OH.这使得长链烃来不及氧化,水相残余的浓度较高.
Abstract:
The oxidation experiments of five crude oil contaminated soils were carried out under two different Fe2+ concentrations and six hydrogen peroxide concentrations. The results showed that the removal of short-chain hydrocarbons C11 - C20 in soil could be improved by the addition of low concentration hydrogen peroxide(225 mmol/L), and the removal of total petroleum hydrocarbons(TPH)came up to 38%. This was due to H2O2 which has a long decomposition time and a low oxygen production rate under low-concentration of hydrogen peroxide conditions(150～225 mmol/L), so that high-intensity·OH can be produced. At this time, the desorption and oxidation of the short-chain hydrocarbon C11 - C20 were balanced, and funther removed by a large amount of oxidation. Under the condition of high hydrogen peroxide concentration(300～900 mmol/L), H2O2 has a short decomposition time and a high oxygen production rate, and only produces low strength ·OH. This makes long-chain hydrocarbons less oxidized and the residual concentration of the aqueous phase is higher.
