摘要：

overmuch heavy metal is one major restrictive factor for land application of sewage sludge. The environmental behavior of heavy metals depends strongly on their specific chemical fraction or binding state in sludge. The present paper gives an overview of recent researches about the chemical speciation of heavy metals in sludge. A detailed discussion was also made on the various problems associated with the distribution of chemical fractions of heavy metals in sewage sludge, which need to be addressed while exploring more efficient treatment of removing heavy metal.
