摘要
内源污染是湖体重要污染源。通过环保清淤,清除污染底泥是降低内源污染负荷的重要措施。针对滇池内源污染的问题,昆明滇池环保清淤工程历经20余年,随着技术的进步,滇池底泥脱水工艺历经多次变革,采用了由单纯自然干化到自然干化与人工辅助干化、土工管袋围堰、底泥脱水固结一体化技术逐步相结合的创新工艺。在此基础上,提出精确疏挖技术、高效底泥脱水减容技术或设备以及底泥的资源化利用是湖泊环保清淤工艺技术发展方向,为国内外湖泊环保清淤、底泥脱水干化及固化底泥资源化利用工艺的选取与发展提供参考。
The environmental dredging project of Dianchi Lake in Kunming has been lasting for more than 20 years.With the advancement of technology,the dewatering process of sediment in Dianchi Lake has undergone many changes,from simple natural drying to gradually combined process of natural drying and artificial auxiliary drying,geotextile containment and dewatering consolidation integration technology,and process of integrating mud dewatering and consolidation technology.Based on the systematic analysis and sorting out of the technological innovation practice of the environmental dredging project,we propose the development direction of the environmental dredging technology,dewatering and drying of sediment and utilization of solidified sediments,and provide reference for the selection and development of environmental dredging,dewatering and drying of sediments and the utilization of solidified sediment resources.
