| 中文摘要 | 含毒性有机物废物直接填埋,对生态环境和人类健康具有危害。试验研究了含苯酚危险废物固化稳定化的效果。进行了固化产物的浸出、长期浸出试验,并分析了微观形貌结构。实验的苯酚质量分数5×10-4,胶结剂为普通硅酸盐水泥(添加质量分数30%和50%),添加剂为粉末活性炭(0~10%)。结果表明:水泥/活性炭固化稳定化可实现苯酚的有效固定;添加少量(质量分数≤3%)活性炭即可显著改善苯酚的固化稳定化效果;28 d养护样品的苯酚累积浸出率远低于7 d养护样品;物理稳定化和化学稳定化协同作用有助于苯酚的固定。; Hazardous wastes containing toxic organic contaminates directly landfilled without solidification and stabilization treatment present risks to the ecology and human health.A leaching test,a long-term leaching test,and micro-structure analyses were used to investigate the effect of cement and activated carbon solidification and stabilization.The initial phenol mass fraction of the synthetic contaminated sand was 5×10-4.Ordinary Portland cement with mass fractions of 30% and 50% was used as the binder,with activated carbon(010%) as the additive.The results show that the phenol is effectively immobilized with very low amounts of activated carbon(mass fraction≤3%) significantly improving the fixation ratios.The cumulative leaching ratios of 28-day cured samples are lower than that of 7-day cured samples with the use of both physical and chemical stabilization fixing the phenol.; 国家“八六三”高技术研究发展计划(2006AA06Z370) |
