The process of dredging reservoirs serves the purpose of preserving water storage capacity and ensuring the functionality of navigational channels. Additionally, it has the potential to mitigate the presence of pollutants and chemicals that pose risks to both the environment and human well-being. This review article examines the many ways of disposal and treatment of dredged sediment, as well as the ecological and economic advantages associated with these approaches. Algae and reed-based treatment methods have the potential to effectively and economically remediate and sustainably manage dredged sediments. Landfills and ocean dumping are widely utilized methods for the disposal of excavated materials. However, other approaches such as land reclamation, the use of fill material, and the preservation of wetlands can offer cost-effective solutions while also contributing to environmental conservation. The implementation of sediment cleaning, stabilization, and solidification techniques has the potential to effectively mitigate waste and improve the quality of sediment, hence facilitating its reuse. Algae and reed-based treatment systems have been found to effectively mitigate disposal costs and contribute to environmental enhancement. Additionally, the practice of reusing dredged sediments has been recognized as a valuable strategy in promoting a circular economy.
疏浚水库的过程旨在保持水库的蓄水能力,确保航道的正常使用。此外,它还有助于减少对环境和人类健康构成威胁的污染物和化学物质的存在。本文综述了疏浚沉积物的多种处理和处置方法,以及这些方法所带来的生态和经济效益。藻类和芦苇处理方法具有有效且经济地修复和可持续管理疏浚沉积物的潜力。垃圾填埋场和海洋倾倒是广泛使用的挖掘材料处置方法。然而,其他方法,如土地开垦、填方材料的利用和湿地保护,可以提供具有成本效益的解决方案,同时也有助于环境保护。采用沉积物清洗、稳定和固化技术可以有效减少浪费并提高沉积物的质量,从而促进其再利用。藻类和芦苇处理系统已被证明可以有效降低处置成本并有助于环境改善。此外,再利用疏浚沉积物已被视为促进循环经济的一种有价值的策略。
