苏州河综合整治三期工程任务之一,是要对河中心城区各130多m3的底泥进行疏浚片,积聚在苏州河的底泥由于重金属等毒性物质沉淀,对中心河道底泥进行挖掘时会上冒污染物而影响水质,这是困扰苏州河底泥片的一个瓶颈问题,因为传统的疏浚方式是采用搅拌法会导致污染加剧。 One of the tasks of the Phase III project of comprehensive treatment of Suzhou Creek is to dredge the sediment of more than 130 m3 each in the downtown of the river. When the sediment accumulated in the Suzhou Creek is precipitated from the sediments of the central riverbed because of the sedimentation of toxic substances such as heavy metals, This will be a bottleneck that plagues the Suzhou River mudflats because the conventional dredging method uses agitation to aggravate the pollution.
