Aiming at the characteristics of poor permeability, high water content and low bearing capacity of waste slurry exhibits, electro-osmosis thermal consolidation was proposed to be used for its reduction utilization, and different temperature conditions was explored to discuss the consolidation effects. The EKG electrode plate was selected as the electrode. The tendency of some parameters, such as displacement, water discharge rate, temperature and current during the consolidation process of the waste slurry at three different heating temperatures, including 40 ℃, 60 ℃ and 80 ℃ were analyzed to compare the physical and mechanical properties before and after electro-osmosis thermal consolidation. The results show that electro-osmosis thermal consolidation can effectively promote the drainage, improve consolidation efficiency, significantly reduce the water content, and enhance the bearing capacity and shear strength of the solidified waste slurry. However, when the slurry was heated to a certain degree, the crack progresses too fast, the conductivity of the slurry is weakened, and the heating efficiency is reduced. And with the higher heating temperature, the heating efficiency is lower. The electro-osmosis thermal consolidation has certain effectiveness and feasibility for the reduction utilization of waste slurry, and this research study will provide reference for practical engineering application.
