Physical remediation and chemical remediation and bioremediation are the important methods for solving heavy metal pollution in soil, combined remediation is raised as the research continues. The sources and current situation of soil heavy metal contamination in our country and its repair mechanism, advantages and disadvantages, the standards and evaluation methods after remediation and research progresses both in domestic and abroad are discussed carefully in the text, on this basis, the author comes up with some issues in the future research and looks forward to the future, in order to have contributions to subsequent researches. |
