Method for preparing sintered bricks by compounding modified fly ash with river sludge
The invention relates to the technical field of sintered bricks, and discloses a method for preparing sintered bricks by compounding modified fly ash with river sludge, which comprises the following steps: (1) dehydrating sludge; (2) stacking and fermenting the sludge; (3) sterilizing the sludge; (4) sequentially adding sludge, modified fly ash, bentonite, coal gangue and expanded perlite into a stirrer, uniformly mixing and stirring, adding water, and stirring to obtain mixed slurry; and (5) injecting the mixed slurry into a green brick mold, carrying out compression molding, demolding, drying and firing to obtain a finished product. The fly ash is subjected to resource utilization, the disposal problem of the fly ash is effectively solved, the environment-friendly significance is great, meanwhile, high economic benefits are achieved, meanwhile, multiple components such as the sludge, the modified fly ash, the bentonite, the coal gangue and the expanded perlite serve as components of the sintered brick, and the sintered brick is environmentally friendly. And the performance of the prepared sintered brick is remarkably improved.
本发明涉及烧结砖技术领域，且公开了一种改性粉煤灰复合河道淤泥制烧结砖的方法，包括以下步骤：（1）将淤泥进行脱水处理；（2）淤泥堆放发酵处理；（3）对淤泥进行灭菌处理；（4）淤泥、改性粉煤灰、膨润土、煤矸石、膨胀珍珠岩依次添加到搅拌机中进行混合搅拌均匀，添加水，搅拌，得到混合浆料；（5）将混合浆料注入到砖坯模具中，进行压制成型，再进行脱模干燥，烧制，得到成品；本发明通过对粉煤灰进行资源化利用，有效的解决了粉煤灰的处置问题，不仅环保意义重大，同时，还具有较高的经济效益，同时，本发明通过以淤泥、改性粉煤灰、膨润土、煤矸石、膨胀珍珠岩多种组分作为烧结砖的成分，制成的烧结砖的性能具有显著的改善提高。
