| 摘 要： | 综述污染底泥的修复技术,探讨其发展状况及存在的问题。目前主要有疏浚、掩蔽等物理修复技术和生物修复技术。物理修复效果明显,但工程量大,投入大;生物修复具有投入低,处理量大,但速度慢,且难以达标。从经费投入和处理效果来看,底泥修复应发展疏浚和生物处理相结合,实现底泥的资源化再利用。在做好污染底泥处理的同时,关键要控制污染源的排放。

| Abstract: | Remediation techniques for polluted sediment are discussed in this paper. The remediation techniques contain physical treatment, such as dredging, capping, and bioremediation. Physical treatment can control contaminated sediment relatively easily, but cost too much, while bioremediation is just reversed. To access legal criterion and reduce cost, various techniques must be applied to treat the contaminated sediments according to their properties. Break down products were suggested to be reused after biodegradation. |
