A water treatment system and a vortex sedimentation device therefor, the vortex sedimentation device (200) comprising a housing and a vortex generator arranged at an inner bottom portion of the housing, the vortex generator producing a vortex at the bottom portion of the housing, heavy solid particulate impurities in the water gathering towards the centre of the bottom portion in a spiral shape under the effect of the vortex. The vortex sedimentation device (200) uses a driving unit to drive rotary blades to rotate and produce the vortex, so that the heavy solid particulate impurities in the water gather towards the centre of the bottom portion in a spiral shape under the effect of the vortex, and the impurities are discharged via a waste pipe. Compared to filter core-type filtration devices in the prior art, the present invention does not require frequent replacement of a cleaning filter core and is simple to operate. The problem that remaining impurities breed bacteria at a filter core and thereby pollute water to be purified does not occur, said problem being caused by the filter core not being replaced in a timely manner. |
