| 摘 要： | 环保清淤是为改善水质和水生态环境而进行的清淤,也是黑臭河道综合治理中的重要环节.本文总结了在珠三角感潮河道底泥环保清淤的工程实践中,较常采用的两个方案:抓斗式挖泥船+泥驳运输方案、绞吸式挖泥船+输泥管输送方案,并由此形成的管道搅拌脱水固结一体化技术、带式机脱水固结一体化技术、板框机脱水固化一体化技术等系列的成熟技术,在环保清淤的处理处置过程中不造成"二次污染",并实现了退水达标排放、固化淤泥资源化利用的目标.

| Abstract: | Environmental protection dredging aims at improving water quality and water ecological environment.It is also an important link of treating black smelly rivers comprehensively.In the paper, two commonly-used plans in engineering practice of sediment environmental protection dredging in Pearl River Delta tidal waterways are summarized: grab dredgers+ dredger pontoon transportation plan and cutter suction dredger + mud pipe transportation plan.Pipeline mixing dewatering consolidation integration technology, belt machine dehydration consolidation integration technology, plate and frame machine dehydration curing integration technology and other mature technologies are formed accordingly."Secondary pollution" is not produced during treatment and disposal of environmental protection dredging.Water-break emission on standard is realized, and solidified sludge is utilized as resources. |
