摘要
矿山重金属污染物主要来自于其固体废物和酸性废水,重金属污染的特点是污染元素种类多,元素价态形式复杂,还附加有选矿药剂的污染;重金属污染过程具有长期性、隐蔽性和累计性;矿山重金属污染的评价方法较多,其中使用最广的是地积累指数法和潜在生态危害指数法;目前矿山重金属污染的修复技术主要有化学性修复和生物修复。
The heavy metal pollution material in the mine is mainly resulted from the solid waste and acid waste water.The heavy metal pollution is characterized by many types of pollution element,complicated element valence state,and the additional pollution of dressing drug.The heavy metal pollution is a long term,cryptic and accumulative problem.There are many assessment methods of heavy metal pollution in mine.The geo-accumulative indices method and potential ecological harm indices method are ones in wide usage.The chemical remediation and biological remediation are the main remediation technology of heavy metal.pollution in mine at present time.
