摘要
污染湖库环保疏浚过程中产生的大量污染底泥堆放在底泥堆场,污染底泥含水率高,在自然条件下难以快速脱水干化,尤其是在雨水充足的地区,会长时间占用堆场土地资源,不利于疏浚底泥后续的处理和资源化利用,并由此导致湖库底泥环保疏浚工作难以大规模地开展。该文在总结分析国内外环保疏浚底泥脱水干化技术的基础上,系统地介绍了不同底泥干化技术及其应用现状,并分析了各自存在的问题,探讨了今后大规模环保疏浚工程中底泥脱水干化技术的发展方向。
During the processes of lakes＇ and reserviors＇ sediment dredging, there exists a large quantities of contaminated sedi- ment produced and discharged in the sediment yard, which has a high water content, and it is difficult to be dewatered rapidly in the natural conditions, especially in rain-rich areas. The contaminated sediment occupies the land resources for a long time, and it will increase the cost of environmental dredging engineering. Based on the domestic and international sediment dewatering technologies, the paper systematically introduced the different sediment drying technology, their application status and their existing problems, which will be the developing trend in the future.
