摘要
现如今,重金属已经成为河道污染的主要污染物。在重金属污染河道底泥的处理过程中,稳定化固化技术是一种最重要且有效的方法。我国河道底泥中的重金属污染物来源于生产废水、土壤冲刷、大气降水以及固体废弃物等几个方面。随着我国相关科学技术的发展,稳定化固化处理技术中的水泥、火山灰质混合材料以及化学药剂等也在河道底泥重金属元素处理中发挥了十分重要的作用,可以在吸附、沉淀各类重金属元素的基础上,提高水体质量。
Nowadays,heavy metals have become the main pollutants of river pollution.Stabilization and solidification technology is one of the most important and effective methods in the treatment of heavy metal polluted river sediment.Heavy metal pollutants in river sediment in China come from production wastewater,soil erosion,atmospheric precipitation and solid waste.With the development of relevant science and technology in China,cement,volcanic ash mixed materials and chemical agents in the stabilization and solidification treatment technology also play a very important role in the treatment of heavy metal elements in river sediment,which can improve water quality on the basis of adsorption and precipitation of all kinds of heavy metal elements.
