基于污泥固化稳定化处理技术的重金属污染河道底泥处置路线

Disposal Route of River Sediments Polluted by Heavy Metals Based on Sludge Solidification and Stabilization Technology

重金属污染河道底泥处理是城市黑臭河道治理中无法回避的问题。针对城市河道底泥的特性,以及对固化稳定化技术在重金属污染底泥处置中适用性及优势的分析和工程运用中影响因素的研究,最终提出基于固化稳定化技术对城市重金属污染河道底泥处置的全流程技术路线,实现底泥处置减量化、无害化、稳定化、资源化,为环境可持续发展提供一种可行性技术模式。

The treatment of the river sediments polluted by heavy metals is an unavoidable problem in the treatment of urban black-odorous rivers. Aiming at the characteristics of urban river sediment, according to the analysis of applicability and advantages of the solidification and stabilization technology in the disposal of river sediments polluted by heavy metals and the study of the influence factors in the engineering application, the whole process technical route of treating the urban river sediments polluted by heavy metals based on the solidification and stabilization technology is finally proposed to realize the minimization, harmlessness,stabilization and reclamation of the sediment disposal, which provide a feasible technical mode for the sustainable environmental development.
