淤泥高效脱水与固化工艺流程研究

Research on silt efficient dehydration and curing technological process

随着经济建设速度加快,在城市排污及地表降雨产沙产污的双重作用下,河湖淤泥淤积速度变得更快、淤积面更大、淤积层更厚,河道湖泊环境受损,蓄水防洪能力下降,必须及时对江湖淤泥进行疏浚处理。本文以广州地区河湖淤泥组分及其基本特性的研究为基础,提出能有效用于该地区淤泥脱水与固化的带格栅杂物预处理功能的淤泥管道搅拌固化技术工艺流程,获得了成功应用。

Silt deposition speed becomes faster, sediment area is larger, and sediment layer is thicker with acceleration of econonfic construction speed under double roles of sand and sediment production due to urban sewage and surface rainfall. River and lake environments are damaged, water accumulation and flood control abilities are reduced, silts in rivers and lakes must be dredged and treated. In the paper, research on sediment composition of rivers and lakes in Guangzhou and their basic features is regarded as foundation for proposing silt pipeline mixing and curing technology process for the efficient dehydration and curing of silt in the region with grille sundry preprocessing function. The technique is applied successfully.
