摘要
阐述了当今污染底泥修复技术方法,以及污染底泥资源化利用途径。目前主要有疏浚、掩蔽和引水等物理修复方法,化学修复和生物修复方法。物理修复效果明显,但投入大;生物修复投入低,修复面积大,但速度慢。底泥资源化利用途径有土地利用,填方材料,建筑材料,污水处理材料等。对各种修复技术和资源化利用途径进行了比较探讨,分析了各种技术方法的优点与不足。
Remediation techniques and resource utilization of polluted sediment are discussed in this paper. The remediation techniques include physical treatments, such as dredging, capping, water diversion, and bioremediation; chemical remediation and bioremedi- ation. Physical treatments can obviously control contaminated sediment, but cost too much, while bioremediation is lust reversed. The resource utilization of polluted sediment is to use sediment as a resource, such as land reclamation, filling material, construction material and waste water material and so on. Advantages and disadvantages of each remediation technique, and resource utilization approaches are analyzed and compared.
