疏浚技术在黑臭水体治理中的应用及生态影响

The application and ecological impact of dredging technology in the process of malodorous black river treatment

在黑臭水体的治理中,疏浚技术是解决水体黑臭的一项重要技术,清淤疏浚可以达到对黑臭水体内源污染进行控制的目的,而疏浚装备和疏浚方式的选择至关重要。另外,疏浚过程中会产生潜在的生态影响,必须采取相应对策以保证疏浚后的生态系统重建。本文介绍了疏浚技术与装备,黑臭水体的疏浚方式,疏浚带来的生态影响及对策,并以上海苏州河综合整治为案例,展示了疏浚的过程以及取得的环保效果。

Dredging is an important technology in the process of malodorous black river treatment. It is well known that endogenous pollution can be controlled by using dredging technologies,and the dredging equipment and dredging method are crucial factors. Moreover,the dredging process would lead to potential ecological impact. This paper introduces the dredging technologies and equipments,the dredging method of black and smelly water,the ecological influence brought by dredging and the countermeasures. Taking the comprehensive treatment of Suzhou River in Shanghai as an example,the process of dredging and the environmental protection achieved are demonstrated. To ensure ecosystem reconstruction after dredging process,corresponding measures are also proposed in this paper.
