Research Progress on the Dewatering Technologies for Environmental Dredge Sediment

环保疏浚过程中产生的大量污染底泥堆放在底泥堆场,不能快速脱水干化,尤其是在雨水丰富的地区,长时间占用土地资源,增加工程投资。本文在总结分析国内外环保疏浚底泥干化技术的基础上,系统地介绍不同底泥干化技术及其应用现状,并分析存在的问题,探讨了今后的发展趋势。

During environmental dredging, a lot of contaminated sediments were produced and discharged in the confined disposal area as dredged materials. The realization of the sediment dewatering was very difficult, especially in rainfall abundance area. Occupying a lot of land for a long time would increase the cost of environmental dredging engineering. Based on the summarizing and analyzing the sediment dewatering technologies for environmental dredge, this paper systemly presented the current status and application of different dewatering technologies and existing problems, and discussed the developing trend in future.
