Abstract— The main purpose of the electro-osmosis method in engineering is to reinforce the foundation. The electro-osmosis method has a lot of research on the foundation reinforcement. The most application is the experiment of electro-osmotic combined loading. The experiment on treatment of heavy metals in municipal sludge by electro-osmotic method is still in a blank state. In this paper, the changes of basic physical properties of sludge before and after electro-osmosis and the changes of heavy metals in sludge before and after electro-osmosis were analyzed. The feasibility of electro-osmotic treatment of heavy metals in sludge was verified by comparing the content of heavy metals in the sludge with the standard value of soil environmental quality after electro-osmotic treatment.
Keywords— Electro-osmotic method, Physical properties of sludge, Heavy metal, Experimental research.
