Sludge solidification agent and sludge solidification method
The invention relates to the technical field of sludge solidification, in particular to a sludge solidification agent, which comprises cement, lime, slag, sodium metasilicate and gypsum. The sludge solidification agent specifically comprises the following components by mass percentage: 1%-30% of cement, 1%-30% of lime, 1%-30% of slag, 1%-20% of sodium metasilicate and the balance gypsum. The sludge solidification method comprises the following steps: 1, removing impurities from sludge; 2, preliminary dehydrating sludge; 3, adding the sludge solidification agent to be mixed with sludge; 4, performing compression molding; and 5, conducting watering and curing to obtain solidified sludge with expected strength. Compared with a traditional sludge solidification technology, the preparation costis reduced, secondary pollution is avoided, waste is treated with waste, and the green and environment-friendly principle is met.
本发明涉及淤泥固化技术领域，具体为一种淤泥固化剂，所述淤泥固化剂包括：水泥、石灰、矿渣、偏硅酸钠和石膏；各组分质量分数为：水泥1％‑30％、石灰1％‑30％、矿渣1％‑30％、偏硅酸钠1％‑20％，余量为石膏。本发明的淤泥固化方法，包括以下步骤：步骤1：淤泥除杂；步骤2：淤泥初步脱水；步骤3：添加淤泥固化剂与淤泥混合；步骤4：压制成型；步骤5：洒水养护得到预期强度的固化淤泥。本发明相比于传统淤泥固化技术降低制备成本，不含二次污染、以废治废，符合绿色环保原则。
