摘要：
Desulfurization sludge is generally characterized by high moisture content and high heavy metal content, leading to difficulty in co-landfilling treatment. This study presents a new type of sludge modification to reduce the moisture content of desulfurization sludge and a new type of curing agent to reduce the leaching concentrations of heavy metals. The moisture content could be reduced to less than 60%. The leaching concentrations of all heavy metals measured by the acetic acid buffer solution method could be reduced less than the standard limits.
