淤泥固化/稳定化技术是一种解决大量淤泥处理难题的有效方法,同时也是进行环境疏浚的配套技术。通过在衡阳平湖对2万m3淤泥的固化处理和工程应用实践,探讨了环境疏浚的基本工艺并重点验证固化/稳定化技术对污染淤泥处理的效果。另外,淤泥固化/稳定化技术可以快速稳定淤泥中重金属等污染物,进而用于填筑用土,解决了淤泥的堆放占地和环境污染问题,为我国湖泊污染淤泥的治理提供了一个有效的处理技术。
Sediment solidification/stabilization technology is not only an effective method for great deal of sediment treatment but also a matching technology for environment dredging.Basic process of environment dredging was discussed,and the sediment treatment effect by solidification/stabilization technology was also verified by the engineering practice of 20,000m3 of sediment in Ping Lake,Hengyang City,Hunan Province.The sediment solidification/stabilization technology can fast stabilize pollutants including heavy metal in the sediment and the solidified sediment can be used for backfilling which solves the problem of sediment stacking and environmental pollution.It is proved as a technology that can effectively treat polluted sediment for the lakes in China.
