A first look at groundwater heavy metal pollution remediation technology
The problem of groundwater pollution,especially heavy metal pollution,has always been highly valued by ex-perts at home and abroad.Through in-depth analysis of the main pathways and causes of heavy metal pollution in groundwa-ter,understanding the research progress of heavy metal pollution treatment in groundwater,and exploring the new technologies and methods for remediation of heavy metal pollution in groundwater.The results are considered:Common heavy metal con-tamination factors in groundwater include anthropogenic and natural causes.Anthropogenic factors are an important cause of heavy metal contamination of groundwater,mainly caused by industry,agriculture and life.Currently,groundwater heavy met-al pollution management methods are mainly two major parts:ex situ and in situ restoration methods.With the increasingly in-depth research on remediation engineering technologies,various remediation engineering technologies have been matured and applied to the comprehensive management of groundwater environmental pollution.In view of the fact that many kinds of heavy metal substances are insoluble and highly toxic,can accumulate in living organisms and have a complex distribution in groundwater,it is necessary to continue to strengthen the research on remediation technologies for heavy metal pollution,so as to make maximum use of and give full play to the effects of remediation technologies for heavy metal pollution and improve the quality of groundwater.
