中新网陕西神木10月3日电题:从黑色枷锁到绿色建材煤基固废上演"变形记" "传统煤基固废的处理方式主要是堆放填埋,就像给大地套上了一层沉重的黑色枷锁。实际上这些看似 无用的废弃物,富含硅、铝、钙等元素,蕴含着巨大的再生潜力。"西安建筑科技大学粉体工程研究所 所长程福安向中新网记者说。 据介绍,每开采燃烧一吨煤,就会产生数百公斤固体废弃物。全国每年新增煤基固废约15亿吨,是目前 存量最大的工业固体废弃物。 记者关注到,位于陕西韩城的煤矸石绿色无害化综合处置示范线每天能"吞食"100吨煤矸石,年产90万 平方米微晶玉石,把原本无人问津的煤矸石变成了价值不菲的建筑材料。"这些项目不仅展示了环保与 经济效益可以同时实现,也让我们看到了固废资源化的广阔市场。"程福安说。 从黑色煤渣到绿色建材,煤基固废"变形记"背后,是污染治理走向资源再生的变革,背后则是技术不断 创新。 历时十余年产学研合作,程福安教授团队已研发出具有自主知识产权的煤基固废制备低碳建筑材料系列 关键技术并应用于产业实践,现在已建成三条工业示范线。 "神木粉煤灰制备云砼石项目年消纳固废60万吨,产出60万立方云砼石,是名副其实的'固废消化器'。 它就像一 ...
