Effect of Bio-charcoal on the Trans of Polycyclic Aromatic Hydrocarbons in Soil- Plant System with Composted Sludge Application
生物质炭输入对污泥施用土壤-植物系统中多环芳烃迁移的影响

The effects of bio-charcoal acted as sludge-composting additive on soil characteristics and plant growth were studied.Compared with the treatment of composted sludge without bio-charcoal,soil cation exchange capacity in treatment of composted sludge with bio-charcoal increased over 5% and 10% respectively and soil nitrogen content increased 13% and 18% respectively for two kind soils.The composted sludge with bio-charcoal also resulted in 23% higher enhancement on ryegrass biomass and 8%-10% higher enhancem...
