Abstract:

The stabilizing treatment,safe disposal and resource utilization of sludge has become a key problem needing emphatic solution. It is found that bioleaching technology can effectively remove heavy metals from sludge,improve dewatering capacity of sludge,eliminate pathogenic bacteria,and control sludge effluviums. It has wide application prospect for the treatment and disposal of sludge,and important meaning to the safe disposal and resource utilization of sludge. The mechanism,influential factors,reactor and process flow of bioleaching technology for removing heavy metals from sludge are introduced in detail. Furthermore,the problems existing in the research and application of sludge bioleaching technology,and its development direction are discussed.

Key words: bioleaching, heavy metals, sludge treatment
