<p>PROBLEM TO BE SOLVED: To provide a contaminated water purifier capable of efficiently pumping a liquid containing floating contaminant and purifying it. SOLUTION: This contaminated water purifier 9 consists of a water pumping means 91 for pumping concentrated liquid 811 of oil-contaminant floating on the surface of oil-contaminated water 80 as contaminated water, and a purifying tank 5 for purifying concentrated contaminant liquid pumped by the water pumping means 91. The water pumping means 91 consists of a water pumping hose 2 provided with a water pump 25, an underwater sensor 11 for detecting a relative position of a sucking port 20 of the water pumping hose 2 against a concentrated layer 81 consisting of the concentrated contaminant liquid, and a hose driving means 3 for lifting and lowering the water pumping hose 2 in accordance with a relative position of the sucking port such that the sucking port is positioned at the concentrated layer.</p> |
