PURPOSE:To efficiently purify the waste water generated from an automobile washing machine in a gas station, etc., and to reuse the purified water without waste by using the title device capable of successively settling, flocculating, filtering, deodorizing, and sterilizing the waste water. CONSTITUTION:The solid matter in the waste automobile washing water generated from an automobile washing machine is settled and separated in a settling tank 1. A flocculant is added into the liq. sent from the settling tank 1 from injectors 19 and 20, the org. matter in the liq. is flocculated in a flocculation tank 2, and the org. matter flocculated and floated in a flotation tank 3 is removed by a remover 25. The water sent from the flotation tank 3 is passed through a filter 5, filtered, and then supplied to a deodorizing and sterilizing device 6. The water is irradiated by the UV rays from the UV sterilizer to oxidize the filtered water with ozone, deodorized, sterilized, and reused. |
