| Abstract: | To study filter bed would be silting is the key point concerning the expectancy service life of the filter project. The paper expound 3 mechanisms how the filter bed be silted. The 3 mechanics are physical silt by deposition, adsorption of suspension and hydrodynamic force, chemical silt by corrosion and mass reproductive microbe. It puts forward some main factors that influences the silt, which are structure characteristics of the filter bed, water quality of river, the condition of water force and the technology of water to be get. |
