Baking-free brick and preparation method thereof
The invention discloses a baking-free brick, which comprises the following raw materials in parts by mass: 10-20 parts of desulfurization slag, 5-8 parts of biochar, 5-12 parts of cement and 1-2.5 parts of an excitant. The desulfurized fly ash is a difficult point of enterprise environmental protection, the baking-free brick is prepared by adopting a curing technology, and a charcoal material formed by converting kitchen garbage and organic pollutants and heavy metal ions in the desulfurized fly ash are cured in a brick body, so that the permeability and dissolution rate of harmful substancesare greatly reduced. The problems of environmental pollution and land occupation of solid waste are solved, resource reutilization is achieved, and the method conforms to the topics of ecological environmental protection and resource saving in the current society.
本发明公开了一种免烧砖，按质量份计算，其原料包括10～20份脱硫渣、5～8份生物炭、5～12份水泥、1～2.5份激发剂。脱硫灰是企业环保的难点，本发明采用固化技术制备免烧砖，将厨余垃圾转化而成的生物炭材料和脱硫灰中的有机污染物、重金属离子固化于砖体内，大幅降低了有害物质的渗透性和溶出率。不仅解决了固体废弃物的环境污染和占用土地问题，还实现了资源化再利用，符合当今社会生态环境保护和资源节约的主题。
