The presence of the elevated concentration of heavy metals, however, represents a serious constraint to implementation of this practice. Microbiological leaching for heavy metal removal from sludge is used for this reason. The principle, efficiency and effect factors of this method are discussed. Fig 2, Tab 1, Ref展开更多
