Study of quickly separating water from tunneling slurry waste by combining vacuum with electro-osmosis

Tunneling slurry waste causes multiple problems, including environmental pollution, and requires transportation and a large landfill space, and therefore, it is important to find a method that can quickly separate water from tunneling slurry waste for metro construction. This paper proposes a practi...

520 |a Tunneling slurry waste causes multiple problems, including environmental pollution, and requires transportation and a large landfill space, and therefore, it is important to find a method that can quickly separate water from tunneling slurry waste for metro construction. This paper proposes a practical method to improve the effect of slurry waste separation by implementing five laboratory tests. The results of these tests reflect that vacuum combined electro-osmosis is a suitable and practical method for treating tunneling slurry waste. The water content after treatment by vacuum combined horizontal electric field electro-osmosis method is not only lower than that after other methods but also close to the liquid limit, which fully meets the requirements of engineering transportation. However, vacuum and filter press dewatering cannot give full play to the drainage effect when the slurry permeability coefficient is too low. This combined technique can improve water separation from the slurry and works well in engineering applications
