摘要

Microbial leaching using Thiobacillus thiooxidans was investigated to solubilize heavy metals (HMs) from domestic sludge at different concentrations. Results obtained showed that 100% Cr was solubilized with 50 ml sludge when the bioleached sludge was digested with 50% (v/v) H₂SO₄, while 90% Cr was also solubilized with the same amount of sludge when the bioleached sludge could not be digested with H₂SO₄. However, 3.0% Cd was the metal least solubilized overall with 100 ml sludge when the bioleached sludge could not be digested with H₂SO₄. For high HM extraction efficiency, digestion using H₂SO₄ must be performed after bioleaching of sludge.
