摘要
当前地下水有机污染日趋严重,传统的原位修复技术存在反向扩散、修复效率低等缺陷,难以达到预期效果.可控缓释技术可延长反应活性组分的释放速率和释放时间,在地下水有机修复中受到了广泛关注.本文通过大量的文献调研,梳理和总结了可控缓释材料的制备及其应用研究现状,并对其今后的发展方向做出展望,以期为实际的地下水修复工程应用研究提供参考.
At present, the organic pollutions of groundwater is becoming more and more serious. Traditional in-situ remediation technologies can not always reach the expectations for theirs reverse diffusion and low remediation efficiency. Controlled release technology can reduce the release rate and prolong the release time of reactive components, which has attracted extensive attention in the remediation of groundwater organic pollution. In this paper, the preparation and application of controlled-release materials are reviewed and summarized. Meanwhile, expectation of the development directions of controlled-release materials is given in order to provide reference for practical application of groundwater remediation engineering.
