Leaching Technology in Remediation of Contaminated Soil Research and Application
The situation of soil pollution prevention and control in China is grim,the trend of regional or regional soil pollution is still prominent,the risk of soil pollution is increasing,and the quality and safety of agricultural products,the safety of human settlements and the ecological environment are still under great threat.This paper mainly analyzed the current research status and progress of chemical clap remediation technology in contaminated soil in our country,focusing on the effects of the factors such as the type,pH,time and dosage of clap remediation on the effect of clap remediation.At the same time,on the basis of conventional leaching technology,this paper also analyzed the research progress of physical and chemical enhanced leaching technology,such as ultrasonic enhancement,microwave enhancement,chemical oxidation/reduction enhancement,and made a further review for the research of soil leaching technology,and finally made a series of prospects for the remediation technology of contaminated soil leaching.
