河湖库底泥清除、处置及资源化利用技术研究进展
Research progress of sediment removal,disposal and resource utilization in river,lake and reservoir
摘要
Abstract
There are a large number of river,lake and reservoir in China and their siltation is serious.It is very necessary to dredge the river,lake and reservoir and make use of the dredged silt.This study reviewed the removal,disposal and resource utilization technologies of siltation in river,lake and reservoir by the following four aspects:1)Main methods of dredging including scour,hydraulic dredging,direct excavation,hank suction desilting and grab bucket dredging,etc.And the advantages,disadvantages and scope of application of several methods of dredging were also described.2)Several common treatment technologies of dredged sediment were systematically sorted out,including flocculation-frame filtration technology,geotube dewatering technology,solidification technology,fluidized solidification soil technology and vacuum preloading technology,etc.The classification,mechanism and effect of mud flocculants were introduced in detail.The mechanism,research status,application direction and main construction steps of solidification technology and fluidized solidification soil technology were summarized.3)Types of pollution in sediment and targeted treatment methods were summarized.The main pollution types of sediment are high nutrient salt pollution,heavy metal pollution and organic pollution.4)According to different treatment methods,dredged silt can be used for building and subgrade backfill,mountain landscape,manufacturing free brick,ceramic production garden greening soil and high standard farmland soil.关键词
