If through observing, outside suction pump and the sand pump device are opened simultaneously to upper portion sewage transformation limpid back, take out the clear water source of sheltering from piece 33 upper portion transformation through the suction pump, take out the silt particle of gathering in silt particle suction opening 7 department through the sand pump device. If the upper sewage is still in a turbid state through observation, the external sand pumping device is opened, and the silt accumulated at the silt suction port 7 is pumped away through the sand pumping device; and then the isolating sheet is opened through the first driving mechanism 6, so that the turbid water on the upper part is precipitated again, isolated, gathered and sucked until the sewage on the upper part is completely clear.
