| 摘 要： | 基于过氧化氢(H2O2)的芬顿或类芬顿试剂被广泛应用于有机污染土壤的修复,但其对土壤性质,微生物群落等影响的研究较少。本文以H2O2和不同的芬顿体系为研究对象,系统考察了H2O2、三氧化二凡(V2O3)/H2O2、柠檬酸铁/H2O2等体系对土壤性质及土壤微生物的影响。结果表明,H2O2在土壤中快速分解,同时伴随着土壤有机质含量的显著下降和土壤铵态氮的显著升高,土壤硝态氮变化不明显。采用高通量测序分析了土壤的微生物多样性和生物群落结构,发现H2O2和芬顿试剂显著降低了土壤微生物的多样性。以上研究为评价H2O2和芬顿试剂修复场地土壤的生态安全评价提供了数据支撑。

| Abstract: | Hydrogen peroxide and Fenton or Fenton-like reactions have been used extensively for the remediation of organic pollutants in the contaminated sites. However, the effects of H2O2 or Fenton reactions on soil properties and microbial communities are not fully understood. In this study, the effects of H2O2 and different Fenton reactions including H2O2, H2O2/V2O3 and H2O2/ citrate chelated ferric on soil properties and microbial communities were studied. The results suggested that H2O2 was decomposed quickly in soil accompany of the obvious degradation of soil organic matter (SOM). Soil ammonium nitrogen increased dramatically, and soil nitrate nitrogen changed slightly. High-throughput sequencing was used to analyze microbial multi-samples and biome structure in soil. It was found that H2O2 and Fenton"s reagent significantly reduced soil microbial diversity. This study provided data support for evaluating the ecological safety assessment of H2O2 and Fenton reagent remediation sites. |
