Sintered brick raw material containing antimony-polluted clay and preparation method of sintered brick raw material
The invention discloses a sintered brick raw material containing antimony-polluted clay and a preparation method, and belongs to the technical field of antimony-polluted soil remediation treatment andresource utilization. The sintered brick raw material comprise antimony-polluted clay, clean clay, pulverized coal and quick lime. The antimony-polluted clay is used for replacing or partially replacing a clay material in a traditional sintered brick, and the addition of the pulverized coal and the quick lime can adjust the cohesiveness, the toughness and the heat of green bricks. During preparation, the sintered brick raw material is subjected to uniform mixing, crushing, aging, blank making and high-temperature sintering, and a sintered brick is obtained. According to the method, antimony can be solidified in the brick and fired into a building material red brick meeting the national standard, the leaching toxicity of antimony in the brick can be reduced by 99% or above, and the environmental risk is effectively reduced.
本发明公开了一种含锑污染粘土的烧结砖原料及制备方法，属于锑污染土壤修复治理与资源化利用技术领域；烧结砖原料包括锑污染粘土、洁净粘土、煤粉和生石灰；本发明使用锑污染粘土替代或部分替代传统烧结砖中粘土材料，煤粉和生石灰的加入可调节砖坯的粘结性、韧性和热量；制备时，烧结砖原料通过混合均匀、破碎、陈化、制坯、高温烧结，得到烧结砖；其可将锑固结在砖块中，烧制成符合国家标准的建筑材料红砖，砖块中锑浸出毒性降低可达到99％以上，有效降低环境风险。
