文摘

Nutrient beads of immobilized SRB were more effective in transforming heavy metals into the more stable bound phases. Inner cohesive nutrient effectively promoted the stabilization process of heavy metals. The excellent removal efficiencies of Cu, Zn, Pb and Cd were 76.3%, 95.6%, 100% and 91.2%, respectively. Easy to recycle and avoid secondary pollution.
