Abstract Three biochar samples were produced by pyrolysis of sewage sludge at the temperatures of 300, 500and 700℃, named as C300, C500and C700, respectively. The C300, C500and C700samples were separately mixed into sewage sludge for aerobic biodegradation, during which the variation of sludge properties was investigated, and the change of heavy metals in the biochars before and after reaction was studied. Results showed that the addition of sludge-derived biochar improved the stability of the products and reduced the bioavailability of heavy metals in the sludges. The most stable product sludge and the lowest bioavailability of heavy metals in the sludge were obtained in the trial with C300, for which the five-day oxygen consumption of the product sludge was 27% lower than that of the control, and the bioavailable contents of Cu, Zn, As and Ni were 24%, 15%, 26% and 19% lower than those of the control, respectively. The contents of water-soluble heavy metals in C300and C500before and after reaction were similar, while the water-soluble Cu, Zn and Ni in C700increased by 16mg/kg, 94mg/kg and 4mg/kg after reaction, respectively. In conclusion, adding C300 to sludge for aerobic biodegradation was recommended.
