摘要
伴随着我国经济的迅猛发展和现代工业的快速增长,产生的重金属废渣越来越多,成分也越来越复杂,对环境和人群健康造成了极大的危害。本文着重介绍了对环境污染最为严重的五种复合重金属废渣:铬铁渣、铜铬铁渣、复合砷渣、铅锌渣以及复合汞渣的物化特性,并从该特性出发,探讨了这几种典型的复合重金属污染废渣资源化利用的途径,旨在为我国可持续发展道路指明方向。
With the economic development and the rapid growth of modem industry in our country, more and more waste residues of heavy metals produce, and its composition is becoming more and more complex, which will do great harm to the environment and human health. The physicochemical properties of five kinds of composite heavy metal-containing waste residues which produce the most serious pollution to the environment are introduced, inclu- ding chromium iron slag, copper chromite slag, composite arsenic slag, lead and zinc slag and composite mercury slag. Based on physicochemical properties of above-mentioned slags, the ways for resources utilization of these typical compound heavy metal-containing waste residues are discussed to give directions for sustainable development in China.
