Alkali-activated regenerated micro-powder-solidified dehydrated sludge/slurry and preparation method thereof
The invention provides alkali-activated regenerated micro-powder-solidified dewatered sludge/slurry and a preparation method thereof. The method comprises the following steps: 1, dehydrating and drying sludge/slurry; preparing regenerated micro-powder by utilizing building solid wastes; determining the composition proportion of SiO2, CaO, Fe2O3 and Al2O3 minerals in the regenerated micro-powder and potential hydration activity; preparing a corresponding alkali activator, and uniformly mixing the alkali activator with the regenerated micro-powder to generate alkali-activated regenerated micro-powder; uniformly mixing the alkali-activated regenerated micro-powder with a proper amount of the dehydrated sludge/slurry to solidify the sludge/slurry; and performing CO2 maintenance treatment on the alkali-activated regenerated micro-powder-solidified dehydrated sludge/slurry. The invention provides the alkali-activated regenerated micro-powder-solidified dehydrated sludge/slurry with high resource utilization rate and environmental friendliness, and the preparation method thereof.
本发明提供一种碱激发再生微粉固化脱水淤泥/泥浆及其制备方法，包括如下步骤，首先，对淤泥/泥浆进行脱水干化处理，再利用建筑固废制备再生微粉，并测定再生微粉中SiO、CaO、FeO、AlO矿物组成比例，以及潜在的水化活性大小，配置对应的碱激发剂与再生微粉混合均匀生成碱激发再生微粉，将其与适量脱水淤泥/泥浆均匀混合，使淤泥/泥浆固化，最后对碱激发再生微粉固化淤泥/泥浆进行CO养护处理，本发明提供了一种资源化利用率高且环保的碱激发再生微粉固化脱水淤泥/泥浆及其制备方法。
