Sewage sludge pyrolysis carbonization
Web15 Feb 2024 · Sewage sludge is commonly dewatered or anaerobically digested before its final disposal, and the most common disposal options are landfilling, land spreading, and … WebMost PAHs (> 89%) are distributed in bio-oil. Compared with those of raw sludge, the total/leachable contents and toxic equivalent quantity (TEQ) of PAHs in biochar are all reduced, suggesting a lower environmental risk for biochar in view of PAH hazard. Notably, the total contents of PAHs in bio-oil reach 55.0–106.6 mg/kg, with high TEQ ...
