| 摘 要： | 疏浚底泥是陆源性入海污染物的主要蓄积场所, 也是海洋污染的潜在污染源。在疏浚和海洋倾倒过程中, 这些疏浚底泥中的污染物会重新释放出来进入水体, 危害海洋环境, 因此对疏浚底泥进行无害或者减害化处理, 对于实施疏浚底泥海洋倾倒的科学管理、有效保护海洋环境具有重要意义。本文综述了6种主要的疏浚底泥处理方法, 介绍和评述了各方法的原理、影响因素以及优缺点, 并展望了物化和生物等方法联合在去除疏浚底泥污染应用中的前景。

| Abstract: | Dredged sediment is the main accumulative site of terrigenous pollutants going into the sea and main potential source of marine pollution. During the course of dredging and marine dumping, these pollutants in the dredged sediment can be released into the sea again, which can harm the marine environment. Therefore, treatment to turn the contaminated dredged sediment into harmless material has significant importance to the scientific management of marine dumping and the effective protection of the sea. The aim of this study is to review six main dredged sediment decontamination and treatment technologies, such as chemical and biosurfactant leaching, thermal treatment, electrodialytic method, ultrasound method, flotation method and bioremediation. The authors discuss the mechanisms of these technologies, effective factors, advantages and deficiencies. Combining several of treatment techniques such as physical, chemical and biological processes is a potentially effective way to treat the polluted dredged sediment in the near future. |
