生物炭修复污染土壤的研究进展

Review on the Remediation of Contaminated Soil by Biochar Amendment

介绍了生物炭的一些基本性质如碱性、表面积、官能团、CEC、元素组成和稳定性。然后对生物炭在污染土壤修复领域中的研究做了综述,例如用作土壤改良剂提高土壤对污水中有机污染物和重金属的吸附能力以及降低土壤中污染物的生物有效性。并对今后生物炭的研究方向作出了展望。

In this paper,the properties of biochar such as the alkalinity,surface area,functional group,CEC,ele-ment content and stability were introduced.Also,the application of biochar in the field of remediation and restora-tion of contaminated soils was summarized,such as the utilization of soil amendment for enhancing sorption of or-ganic pollutants or heavy metals from wastewater and reducing the bioavailability of these contaminants.Finally,the future research direction of biochar was forecasted briefly.
