| titleOfInvention | A kind of method of sludge biochar resource utilization |
| abstract | The invention discloses a method for resource utilization of sludge biochar. The method includes finely grinding and magnetically separating the biochar prepared from the sludge to obtain ferrous magnetic material and iron-free biochar micropowder; wherein the biochar micropowder is dry premixed with cement and an early strength agent to obtain a premix; Add river sand and mix to obtain a secondary mixture; disperse the water reducing agent and water evenly in a mixer, add the secondary mixture to obtain a third mixture; send it into a mold for pressure molding; place the mold in a steaming box , After steam curing, it is lowered to room temperature, and the mold is removed after the green body is solidified; concrete solid bricks, blocks or thermal insulation materials are obtained by curing at room temperature. The method solidifies harmful heavy metals in sludge, avoids secondary pollution to the environment, and directly prepares solid concrete bricks to realize sludge resource utilization and large-scale treatment, and is especially suitable for biochar obtained by pyrolysis of heavy metal-containing sludge processing. The process is simple, the cost is low, and it has good economic and environmental benefits. |
