土壤重金属污染及修复技术综述

Review of Soil Heavy Metal Pollution and Technology

近几年来,环境污染事件频发,环境污染直接或间接地影响了人们的生活以及健康。人们对环境问题的关注日益增多,其中不少为土壤的重金属污染问题。本文参照了大量的国内外相关文献,阐述了当今世界土壤重金属污染的现状和特点,土壤修复技术的研究进展以及应用情况。本文较详细的综述了重金属土壤修复的技术,其中包括物理、化学以及生物修复技术的介绍、优缺点以及应用范围。最后,本文提出了一些修复技术应用以及土壤污染管理的建议。

In the contemporary society, environmental pollution incidents happened frequently. Environmental pollution directly or indirectly affects people＇s lives and health. People pay more and more attention to environmental problems, and many of them are heavy metal pollution in soil. Referencing to the relevant literature at home and abroad, this paper provides a critical view about the current world soil heavy metal pollution status and characteristics, and summarizes the research progress and application of soil remediation technology. And this paper particularly reviews the technology of heavy metal soil remediation, including introductions, advantages, disadvantages, and application of physical, chemical and bioremediation technology. At the end, the article puts forward some suggestions about the application of the technology and some management to the polluted soil.
