新型环保清淤及淤泥无害化处理技术——以常州长荡湖综合治理项目为例

New environmental dredging and sludge harmless treatment technology——Taking Changzhou Changdang Lake comprehensive treatment project as an example

以江苏常州长荡湖综合治理项目为例,研发并采用了新型环保清淤及淤泥无害化处理技术。该技术通过精准抽吸防止沉积污染物扩散造成内源污染。脱水环节以高通量滤袋为工艺主体,通过空泡打碎、高效絮凝、重金属吸附、重力压缩、自然干化、高通量滤袋过滤等作用,实现了淤泥的高效、节能、绿色、环保脱水。干化淤泥泥质较好,无需再进行稳定化、无害化处理,可作资源化处置。

Taking Changdang Lake comprehensive treatment project in Changzhou,Jiangsu as an example,a new environmental dredging and sludge harmless treatment technology were developed and adopted.The technology prevented the deposition of pollutants from spreading and causing endogenous pollution by precise pumping.The dehydration process took the high-flux filter bag as the main body of the process.Through cavitation breaking,efficient flocculation,heavy metal adsorption,gravity compression,natural drying,high-flux filter bag filtration and other functions,the sludge could be dehydrated efficiently,energy-saving,green and environmentally friendly.The dry sludge had better mud quality,no need for stabilization and harmless treatment,and could be used as a resource disposal.
