摘要
在石油开采、运输、储存等过程中,原油及其制品进入土壤,会导致土壤污染。生物炭具有高吸附能力、高比表面积、高微孔率和离子交换能力等特性,可以通过化学或物理作用吸附土壤中的污染物;生物炭通过影响土壤微生物群落结构,使其丰度变化,从而促进土壤中石油烃及多环芳烃的生物降解。对生物炭的生产及特性、去除土壤中石油烃及多环芳烃机理、与生物炭环境应用相关的动力学研究和对污染物生物降解的影响等方面进行了概述,在此基础上对生物炭修复油污污染土壤未来研究方向进行了展望。
Various processes including oil extraction,transportation and storage release crude oil and its products into soil with pollution,the most serious environmental problems today.Biochar with the characteristics of high adsorption capacity,high specific surface area,and high microporosity and ion exchange capacity,can adsorb pollutants chemically or physically while promoting the biodegradation of petroleum hydrocarbons and polycyclic aromatic hydrocarbons in soil by affecting soil microbial community structure and abundance.This paper summarizes the production and property of biochar and its environmental application for removing petroleum hydrocarbons and polycyclic aromatic hydrocarbons pollutants in soil and focuses on associated mechanisms of petroleum hydrocarbon adsorption kinetics and biodegradation.In addition,the future biochar remediation of oil-contaminated soil is prospected.
