| description | The invention discloses a papermaking deposition slag resource recycling process, which comprises the following steps of: 1, sufficiently disintegrating papermaking deposition slag to respectively obtain coarse pulp, heavy impurities and deposition slag tailings; and 2, respectively recovering the crushed coarse pulp, heavy impurities and deposition slag tailings. The process has the beneficial effects that the resource recovery rate of the papermaking deposition slag is greatly increased, no waste pollution is generated in the whole process, and water resources are fully utilized.
本发明公开了一种造纸沉积渣资源化回收工艺，包括以下步骤：一是将造纸沉积渣经过充分碎解后，分别得到粗浆、重杂质和沉积渣尾料；二是分别对碎解后的粗浆、重杂质和沉积渣尾料进行回收处理。本发明的有益效果具体表现在大大提高造纸沉积渣的资源回收率，且整个工艺不产生废物污染，达到水资源的充分利用。 |
