摘要
近年来,我国河湖底泥中有机污染问题日益突出,底泥中存在大量的有机污染物,如氯酚类、多环芳烃类以及多氯联苯类等,若不及时处理,释放到上覆水环境中会对生态环境、人体健康和社会经济的可持续发展产生严重危害。目前,针对河湖底泥有机污染的修复技术已成为环境治理领域的重要研究方向。当前底泥有机污染的治理技术包括原位修复技术和异位修复技术,而原位修复技术已成为治理河湖底泥有机污染的主要技术手段。主要介绍了底泥原位修复技术中的活性覆盖技术、生物修复技术、化学修复技术以及联合修复技术及其研究进展,并对各种原位修复技术的发展和应用前景提出了展望,以期为后续对原位修复底泥技术的研究与应用提供参考。
In recent years,the sediment organic pollution problems in rivers and lakes are increasingly prominent in China,and there are various organic pollutants in sediment,such as chlorine phenolic,polycyclic aromatic hydrocarbons,and polychlorinated biphenyls,etc.,posing threat to the ecological environment,human health.Recently,in-situ remediation technology for river and lake sediments emerged as a significant research direction in environmental governance.At present,the remediation technology of organic pollution sediment includes in situ remediation and ectopic remediation,and in situ remediation technology has become the main technical means of treating pollution of the river and lake sediment.In this article,the research progress of active covering technology,bioremediation technology,chemical remediation technology and combined remediation technology in in-situ remediation technology is introduced,and the development and application of insitu remediation technology are also proposed,hoping to provide guidance for the follow-up research and application of in-situ remediation technology for sediment.
