摘要
河道底泥作为长江下游地区的一种复杂固废,需要慎重处置,以避免重金属等有害物质造成二次污染。为实现对长江下游某河道底泥的安全高效综合利用,对回填现场的河道底泥进行了取样、检测、分析,对其固废属性进行判别。经过对该河道底泥的反应性、易燃性、腐蚀性、浸出毒性、毒性物质含量等特征进行详细核查,认定该河道底泥不属于危险废弃物,为Ⅰ类一般工业固体废物,建议按照Ⅰ类一般工业固体废物进行处置。
As a kind of complex solid waste in the lower reaches of the Yangtze River,river sediments need to be carefully disposed of to avoid secondary pollution caused by harmful substances such as heavy metals.In order to realize the safe and efficient comprehensive utilization of the sediment of a certain river in the lower reaches of the Yangtze River,sampling,testing and analysis of the sediment of the river at the backfill site were carried out,and the properties of the solid waste were judged.After detailed verification of the characteristics of the river sediment,such as reactivity,flammability,corrosion,leaching toxicity and toxic material content,it is concluded that the river sediment is not hazardous waste,and it is Class I general industrial solid waste.It is recommended to dispose according to Class Ⅰ general industrial solid waste.
