Abstract

In practical engineering, electro-osmotic treatment of large-scale silt projects will cause a lot of electricity waste. Some scholars have made an electro-osmotic method to treat silt and combine pile-loading to reduce the energy consumption of electric energy. In this paper, the effects of electro-osmotic treatment combined with pile-loading experiment on the consolidation of municipal sludge and the content of heavy metals in the sludge before and after electro-osmosis are analyzed and the conclusions are drawn.(1)The combination of electro-osmotic method and pile-loading experiment has strong capacity of drainage consolidation.(2)The contents of copper and zinc decreased obviously, and the electro-osmotic method combined with pile-loading method had a certain effect on the treatment of heavy metals in silt.
