生物质修复石油污染土壤的研究进展

Research Progress of Biomass Remediation Technology for Oil-contaminated Soil

随着石油污染土壤问题的日益突出,对石油污染土壤修复的研究也越来越多。主要综述了畜禽粪便、园林废弃物、小麦秸秆等生物质在修复石油污染土壤方面的作用。对生物质的利用主要包括三种:直接施加到土壤上、和被石油污染的土壤进行生物堆肥以及经高温裂解得到生物炭来修复石油污染土壤。这几种方法都能够在一定程度上对石油污染土壤进行改善和修复。不过,这些方法都还只局限于实验室研究,还需要进一步研究将其应用于实际中。

As the problem of soil contaminated by crude oil becomes increasingly prominent, the research on remediation of petroleum contaminated soil is also more and more. In this paper, the effect of the biomass, such as poultry excrement, garden waste and wheat straw, on the remediation of petroleum contaminated soil was summarized. The use of biomass mainly includes three types： direct addition to the soil, bio compost with oil-contaminated soil and use of biochar obtained by high temperature pyrolysis of biomass. These methods can improve and repair the oil contaminated soil in a certain degree. However, these methods are only limited to laboratory research, and further research is needed to be used in practice.
