Harmless treatment method for sludge
The invention provides a sludge harmless treatment method, and belongs to the technical field of sludge treatment, and the sludge harmless treatment method comprises the following steps: S1, dehydrating sludge dug out from a river channel through a soil dehydrator, and screening to remove large-particle impurities to obtain dried sludge; s2, cement, fly ash, quartz sand, dried sludge, modified TiO2, a water reducing agent and mixing water are uniformly mixed, and mixed slurry is obtained. The dredged sludge is used as a raw material, the river channel can be dredged, the water area can be beautified, waste can be turned into wealth, and cyclic utilization of resources is achieved; by modifying the sludge, on one hand, the mechanical property of the charcoal-fired sludge is improved, on the other hand, the gap exposure of the charcoal-fired sludge is reduced, the leaching of harmful components is reduced, and the environment protection is facilitated.
本发明提供了一种淤泥无害化处理方法，属于淤泥处理技术领域，包括如下步骤：S1将从河道内挖出的淤泥通过泥土脱水机进行脱水、筛分除去大颗粒杂质后得到干化淤泥；S2：将水泥、粉煤灰、石英砂、干化淤泥、改性TiO2、减水剂、拌合水混合均匀得到混合浆料。本发明使用疏浚淤泥作为原材料，既能疏通河道、美化水域又可以变废为宝，实现资源的循环利用；通过对淤泥进行改性，一方面提高了炭烧淤泥的力学性能，另一方面减少了炭烧淤泥的空隙暴露，降低了其有害成分的浸出，有利于保护环境。
