摘　　要：评估了污水处理厂污泥用于生产红砖的可行性。处理污水的过程会产生大量污泥,主要是有机污泥,这些污泥通常被填埋在垃圾填埋场。通过微观结构和物理力学分析,评估了两种不同类型的污泥(从0~10%代替黏土)作为红砖生产的原材料使用。结果表明,污泥的加入降低了砖的表观密度,增加了砖的风化敏感性,这是由于在烧制过程中产生了更高的孔隙率。在生产红砖的黏土混合物中加入6%的污泥是一种可行的、可持续的、低环境影响的回收解决方案。In this paper,the feasibility of recycling sludge from sewage treatment plants for the production of red bricks is evaluated.The process of treating sewage produces large amounts of sludge,mainly organic sludge,which is often landfilled.In this study,two different types of sludge(from 0~10%instead of clay)are evaluated as raw materials for the production of red bricks through microstructural and physicomechanical analysis.The results show that the addition of sludge reduced the apparent density of the bricks and increased the weather⁃ing sensitivity of the bricks,which is due to the higher porosity generated during the firing process.Adding 6%sludge to the clay mixture used to produce red bricks is a viable,sustainable,low-impact recycling solution.
