一种利用生活垃圾焚烧灰渣污泥制备的陶粒及其制备方法
摘要：
本发明公开了一种利用生活垃圾焚烧灰渣污泥制备的陶粒及其制备方法。该陶粒主要由以下质量百分数的固体原料所制成：生活垃圾焚烧灰渣污泥60％～75％，粉煤灰10～15％，粘土10％～30％，膨胀珍珠岩5～10％；除上述固体原料外，还加入占上述固体原料总质量20％～40％的水。本发明的陶粒主要由生活垃圾焚烧灰渣污泥制备而成，实现变废为宝，化废料为资源；制备的陶粒符合轻集料及其试验方法的标准要求，强度大，密度小；同时本发明的制备方法简单方便，成本低，原料来源广泛，成品周期短。
摘要（英）：

The invention discloses a ceramsite prepared by utilizing municipal waste incineration ash residue sludge and a preparation method thereof. The ceramsite is mainly prepared from the following solid raw materials in percentage by mass: 60 to 75% of municipal waste incineration ash residue sludge, 10 to 15% of fly ash, 10 to 30 parts of clay and 5 to 10% of expanded perlite. Besides the solid raw materials, water which accounts for 20 to 40% of the total mass of the solid raw materials is also added. The ceramsite disclosed by the invention is mainly prepared from the municipal waste incineration ash residue sludge, so that the wastes are turned into treasures and are used as resources. The prepared ceramsite meets a standard requirement on a lightweight aggregate and a testing method of the lightweight aggregate, is high in strength and is small in density; meanwhile, the preparation method disclosed by the invention is simple and convenient, the cost is low, the sources of raw materials are wide, and the period of a finished product is short.
