Besides, the leaching amount of heavy metals in both materials was very small, and it could meet the corresponding leaching toxicity security standards. Comparatively, expanded shale can solidify heavy metals more efficiently than sintered brick.
结果显示,在相同烧成温度下,与纯污水污泥焚烧相比,污水污泥页岩陶粒和烧结砖的重金属挥发量明显降低;另外,污水污泥页岩陶粒和烧结砖中的重金属浸出浓度都非常低,符合浸出毒性的安全标准;相比而言,陶粒比烧结砖对污水污泥中的重金属有更好的固化能力。
