The invention discloses a method for intensively removing 
heavy metals in 
sludge by using an electroosmosis 
dehydration device. The method for intensively removing 
heavy metals in 
sludge by using an electroosmosis 
dehydration device comprises the following steps of: adding a certain 
mass of inorganic salt or chelating agent into 
sludge, uniformly stirring to obtain mixed sludge, setting electroosmosis 
dehydration process parameters, and dehydrating the mixed sludge by using the electroosmosis dehydration device to remove the 
heavy metals in the mixed sludge, the chelating agent being an 
organic acid containing at least one carboxyl group, and being easy to chelate with heavy metals in the sludge. By adding the inorganic salt or the chelating agent into the sludge, the removal rate of heavymetals in the sludge in the electroosmotic dehydration process can be increased, meanwhile, the 
moisture content of a 
sludge cake of the dehydrated sludge is low, the 
effective volume reduction of the sludge is realized, and the subsequent treatment and utilization of the sludge are facilitated; the added inorganic salt does not cause secondary 
pollution to the sludge, and the added chelating agent is degradable and environment-friendly.
