| 中文摘要: |
| 随着“无废城市”建设工作的推进，粉煤灰造成的土地和环境的污染问题急需解决。粉煤灰由于物理和化学性质特殊，可当作一种潜在的资源，因此如何合理利用粉煤灰成为众多企业的研究重点。介绍了粉煤灰的性质、分类和成分，并探讨了粉煤灰在多个领域的应用。比较了粉煤灰主要利用途径的优缺点和应用前景，并通过分析得出：附加值较高的利用途径，其处理成本也较高，粉煤灰的消纳量较少，存在的问题也较多，而且大多数研究尚处于实验室阶段，还未实现工业化利用。最后，针对如何提高粉煤灰的资源化利用率提出了相应的措施和建议。 |
| 英文摘要: |
| With the advance of “zero-waste city” construction, it was urgent to deal with the land and environment pollution caused by coal fly ash. Meanwhile it was a potential resource in terms of physical and chemical properties of coal fly ash. However, its reasonable utilization has become a research focus for multiple enterprises. The properties, classification, and composition of coal fly ash were introduced firstly. Its various applications were discussed. And their merits and demerits were compared. Their application prospects were proposed. A conclusion was drawn that high value-added utilization of coal fly ash required high treatment cost along with lower consumption. Some problems existed simultaneously. Most of them stayed in a lab scale without industrial applications. Some suggestions and measures for improving resource utilization of coal fly ash have been put forward. |
