| 摘 要： | 对于As浸出率超标的硫酸废水处理系统污泥,应用固化处理可以有效降低砷浸出率。文章用水泥及粉煤灰固化冶炼厂硫酸废水中和污泥,以As的浸出率为控制指标,从时间、物料配比、pH值等方面考虑对固化块浸出率的影响,寻找粉煤灰最佳掺入量,有效降低处理成本,并尽量减少固体废物对环境的有害影响。与水泥固化相对比,采用粉煤灰固化具有更好的固化效果和明显经济效益。

| Abstract: | Solidification of sludge in sulphuric acid wastewater treatment system with fly ash and cement was studied. The affecting factors including time, additives, proportion of materials, caring condition and pH were analyzed. Comparing with cement solidification, fly ash solidification was much more economical. |
