River silt filter presses are used for river dredging, but they all face the problem of how to deal with the silt. Silt usually contains a large amount of organic matter, pathogenic microorganisms, heavy metals, and nitrogen, phosphorus and other substances, because of its own poor permeability, solidification difficulties, so it is easy to pressure rheology, not easy to transport. Traditional dredging slurry...
