生物炭-植物对重金属污染土壤联合修复机制研究进展

Research Progress of Biochar-Plant Joint Remediation Mechanism of Heavy Metal Contaminated Soil

近年来,由于工农业的快速发展,农用化学品的数量和多样性随之增加,对环境造成极大挑战,其中重金属对环境和食品的污染,影响了人类健康。常规的修复方法例如:物理修复法、化学修复法、生物修复法等,都有一定的局限性,而生物炭因其超强的吸附性能,被广泛应用于碳固定和环境的修复中,为了提高修复的效率,生物炭与植物联合修复技术被广泛应用。本文通过对生物炭和植物联合修复的特点机制进行简述,总结联合修复机理,以期为重金属污染修复提供理论依据。

In recent years,due to the rapid development of industry and agriculture,the quantity and diversity of agricultural chemicals have increased,which has brought great challenges to the environment.Among them,heavy metal pollution has a great impact on the environment and food,and affects human health.Conventional remediation methods,such as physical remediation,chemical remediation and bioremediation,have some limitations.Biochar is widely used in carbon fixation and environmental remediation because of its strong adsorption performance.In order to improve the efficiency of remediation,biochar and plant combined remediation technology is widely used.This paper briefly describes the characteristics and mechanism of the combined remediation of biochar and plants,and summarizes the mechanism of the combined remediation,in order to provide a theoretical basis for the remediation of heavy metal pollution.
