Environment-friendly sludge baking-free brick prepared from municipal sludge and multi-component coal-based solid waste and preparation method of environment-friendly sludge baking-free brick
The invention discloses an environment-friendly sludge baking-free brick prepared from municipal sludge and multi-component coal-based solid waste and a preparation method of the environment-friendly sludge baking-free brick, belongs to the field of solid waste treatment and resource utilization, and aims to solve the problem of high cost in the drying process of the municipal sludge. The environment-friendly sludge baking-free brick comprises the following components in parts by mass: 30-50 parts of municipal sludge, 15-25 parts of carbide slag, 35-45 parts of fly ash, 1-5 parts of desulfurized gypsum and 10-15 parts of standard sand. With the environment-friendly sludge baking-free brick and the preparation method thereof adopted, the municipal sludge can be digested and degraded to a great extent, a large amount of solid waste can be comprehensively utilized, and the economic concept of low-carbon cycle development is met; and sludge with a certain water content and a non-burning process are utilized, so that energy consumption and environmental problems caused by the burning process are reduced, and the requirements of energy conservation and emission reduction are met. The prepared environment-friendly sludge baking-free brick is high in compressive strength and good in durability.
一种利用市政污泥和多组分煤基固废制备环保污泥免烧砖及其制备方法，属于固体废弃物处理与资源化利用领域，属于固体废弃物处理与资源化利用领域，可解决市政污泥在干化过程中高成本的问题，包括如下质量份数的组分：市政污泥30‑50份、电石渣15‑25份、粉煤灰35‑45份、脱硫石膏1‑5份、标准砂10‑15份。本发明不仅可以极大程度上消化降解市政污泥，而且可以对‘大宗固废’进行综合利用，符合低碳循环发展的经济理念；本发明的利用一定含水率污泥及免烧工艺，有利于降低能耗以及烧制工艺所带来的环境问题，符合节能减排的要求；本专利所制环保污泥免烧砖抗压强度高、耐久性好。
