土壤重金属污染与修复技术研究

Study on heavy metal pollution and remediation technology in soil

由于我国工业化不断的发展、矿产资源的不合理开发利用、农药的不合理利用、污水浇灌农田等,加剧了土壤污染。至今,污水灌溉的占地面积达到135万hm2左右,重金属污染则达到该面积的64%左右。土壤重金属污染引发的农产品质量安全问题等群体性事件逐年增多,严重危及到人民群众的健康安全,如不及时采取防治措施,将严重影响社会稳定和经济发展。面临此现象,我们主要采取工程、物理-化学以及生物修复技术去解决,从而为土壤重金属污染修复治理提供科学依据。

Due to the continuous development of industrialization, the unreasonable development and utilization of mineral resources,the unreasonable utilization of pesticides, and the sewage irrigation of farmland,the soil pollution is intensified. Up to now, sewage irrigation covers an area of about 1.35 million Hm2,and heavy metal pollution accounts for about 64% of the area.The quality and safety problems of agricultural products caused by heavy metal pollution are increasing year by year, which seriously endangers the health and safety of the people.If the prevention and control measures are not taken in time,it will seriously affect social stability and economic development.Facing this phenomenon, we mainly adopt engineering, physical-chemical and bioremediation technology to solve it,so as to provide scientific basis for remediation of heavy metal pollution in soil.
