| Abstract: | By designing of the bioleaching experiment,the removal rate of heavy metals from sludge was discussed under various conditions,and they were evaluated by the potential ecological risk index(PERI) of Hakanson method.The study shows that the bioleaching of Cu,Pb,Zn,Cr and Ni obviously depends on the concentration of sulphur powder and sulphuric acid.After 14 days of bioleaching,the removal rate of Cu,Pb,Zn,Cr and Ni adding sulfur in sewage sludge were 96.8%,53.2%,94.2%,97.5% and 103.0%,respectively.The result... |
