PURPOSE:To provide the objective apparatus efficiently performing the cleaning work of a road culvert or sewer pipe. CONSTITUTION:A sand sedimentation tank 1 separating earth and sand of polluted water taken out of a road culvert or sewer pipe, a screen filter device 2 roughly filtering supernatant water of the sand sedimentation tank 1, a flocculation reaction tank 3 flocculating a contaminant in roughly filtered water, a sedimentation tank 4 sedimenting the flocculated contaminant, a rotary drum type continuous filter device 5 finely filtering supernatant water of the sedimentation tank 4 and using a part of the obtained purified water to collect conc. water of the contaminant and a concn. water storage tank 5 sending conc. water to the sedimentation tank 4 by a pump 59 are provided on the bed of a truck 8. Further, a sedimented matter flocculation reaction device 6 flocculating the sedimented matter of the sedimentation tank 4, a fabric running type dehydration device 7 dehydrating the flocculated sedimented matter to take out the same as a cake and a waste water storage tank 75 sending waste water squeezed but by dehydration to the sedimentation tank 4 by a pump 76, etc., are mounted on the bed of the truck 8. |
