河道底泥重金属的修复技术

Remediation Technology of Heavy Metals in River Sediment

河道底泥是河道水环境的重要组成部分,一旦底泥受到污染,整个河流水环境都会受影响。针对重金属污染的底泥,介绍了底泥重金属的影响因素及危害,并全面综述了目前国内外对底泥重金属的修复技术包括物理、化学和生物修复等,同时也对这些修复技术的原理、动态和优缺点进行了分析,为河道底泥重金属的修复提供科学依据和技术支持。

River sediment is an important part of river water environment. Once the sediment is polluted, the whole river water environment will be affected. Aiming at the sediment polluted by heavy metals, the influencing factors and hazards of heavy metals in sediment were introduced, the current remediation technologies of heavy metals in sediment at home and abroad were comprehensively summarized, including physical, chemical and biological remediation, and the principle, dynamics, advantages and disadvantages of these remediation technologies were analyzed, so as to provide scientific basis and technical support for the remediation of heavy metals in river sediment.
