| Abstract: | Objective] The research aimed to study leaching effect of the heavy metal in sludge by A.niger.Method] By using batch shaking culture,influences of the leaching time,sludge content,inoculum concentration,initial pH and carbon concentration on removal rate of the heavy metal in sludge were studied.Result] A.niger was cultivated under the conditions of temperature of 30 ℃,carbon concentration of 8%,inoculum concentration of 2×106 spores/L,and sludge content of 1.0% for 12 d.Result showed that removal rates of the Zn,Cd,Cu and Pb in sludge by A.niger were respectively 83.6%,87.8%,70.4% and 75.6%.Conclusion] Bio-leaching by A.niger could effectively remove heavy metal in sludge. |
