[0028] When in use, first pour the printing and dyeing sludge into the drying device 5, drive the large drum 505 to rotate through the stepper motor 503 to spin out most of the water in the sludge, then fully dry the sludge through the drying box 509, then add the straw into the mixing barrel 401 through the feeding port 403, turn on the servo motor 404 to drive the mixing blade 406 to rotate, so that the straw and the dried sludge are fully mixed, and the sludge after mixing is transported to the pyrolysis carbonization device 1 through the first conveying pipe 6.

The exhausted gas enters the purification box 301, and is discharged into the air after being filtered through the first filter plate 303, the second filter plate 304 and the activated carbon filter plate 305. After the carbonization is completed, the generated biochar enters the activation box 9, and oxygen-containing gases such as water vapor and flue gas are used as activators.

In addition, the heavy metal ions in the sludge are combined with the solidified carbon with stable chemical bonds, and the heavy metal ions are transformed from the original extractable state to the stable state, which is difficult to separate from the carbon, so that it cannot be leached in the environment, and no secondary pollution will be generated, thereby achieving the harmlessness of the sludge. Through the setting of the purification mechanism 3, the gas generated by the cracking can be effectively filtered, and the purpose of harmless emission can be achieved.
