Effect of Biochar on Nitrate Removal in a Pilot-Scale Denitrifying Bioreactor.

abstract：:Heavy metal pollution of soil has been recognized as a major factor impeding soil microbial processes. From this perspective, we studied responses of the soil biological activities to metal stress simulated by soil amendment with Zn, Pb, and Cd chlorides. The amounts of heavy metal salts added to five metal-polluted s...
