摘要
河流、湖泊等水体底泥污染问题已引起全世界的广泛关注,尤其重金属污染问题。目前国内对河流、湖泊底泥重金属的研究偏重于重金属的分布、污染特征以及重金属对生物、生态的影响,对底泥重金属的治理研究相对较少。分析了底泥中重金属的释放机理,简单介绍治理底泥重金属的一些生物技术,着重讨论当今处理底泥重金属的化学方法。
The pollution of sediment of rivers and lakes became a global problem, especially heavy metal pollution. At present,most of researches of heavy metals in sediment fasten on distribution,pollution characteristics, influencing of biological and ecological in China, treatment of sediment＇s heavy metal research was relatively few. This study analyzed the theory which heavy metal discharge from sediment, and illustrated treatments of sediment＇s heavy metal by using biotechnology and chemical technology at this moment.
