Different from the currently commonly used sludge disposal processes such as landfill, composting, and incineration, this project adopts sludge pyrolysis and carbonization technology: a The processing speed is fast, the cycle is short, and the processing volume is large; b. The reduction is thorough, and the carbon does not contain water; c Thorough harmlessness, after pyrolysis and carbonization treatment, 100% of all harmful pathogens can be killed; d Completely eliminate antibiotic residues, and completely decompose and harmlessly remove the residual antibiotics that cannot be completely removed by composting technology; e. The stabilization of heavy metals makes the existence of heavy metals more stable; f The amount of pollutants produced is low, and the emissions of CO2 and NOX are greatly reduced, there is no fly ash pollution, and the pollutant control link is simple.
