摘要
城市内河由于长期承纳污染物导致其底泥受到污染,特别是重金属污染严重。为达到资源再利用要求,研究了3种不同配方的固化剂对其固化的效果。结果表明,随着固化时间的延长,固化淤泥的含水率降低,无侧限抗压强度(UCS)升高。重金属得到很好的固定化处理,重金属的浸出量、浸出率均有明显降低而且达到标准要求。
The Urban River has received pollutants for a long time, especially for heavy metals. In order to meet the requirement of contaminated sediment reutilization, three different formulations of stabilizer was used liar treating the sediment. The results show that the moisture content of the solidified sediment decreased and the unconfined compressive strength （UCS） increased with solidification time. The heavy metals are well stabilized, and their leaching amount and leaching ratio obviously decrease and meet the requirements.
