摘要: Soil pollution caused by petroleum pollutants from production trade activities in petroleum-related factories contributes serious threat to the environment and human health. Composting is technically-feasible and cost-effective in the biodegradation of heavy oil pollutants. This composting experiment was developed with four rice husk biochar (RHB) concentrations of 0 wt% (CK), 5 wt% (S1), 10 wt% (S2) and 15 wt% (S3) for the degradation of heavy oil. The results showed that RHB amendment could strengthen the degradation perfor-mance of heavy oil, and the degradation efficiencies for CK, S1, S2 and S3 were 59.67%, 65.00%, 73.29% and 74.82%, respectively. Microbial community succession process was investigated through high-throughput sequencing technology, and the RHB addition regulated bacterial community succession and further effec-tively facilitated the biodegradation of heavy oil in composting. This study substantiated that biochar materials -amended aerobic composting would be a promising strategy for the biodegradation of petroleum pollutants.
