PURPOSE: A pressurized floatation type polluted water treating method with a micro-bubble unit and a slanted plate structure is provided to minimize the installing area of a polluted water treating facility and to stably operate the facility without malfunction. CONSTITUTION: A floatation separating bath(20), a scum eliminating unit(40), a slanted plate(30), a hopper, a sludge transferring pump, a treated water bath(50), a pressurization dissolving bath(60), and a micro-bubble adjusting nozzle(70). The flotation separating bath is divided into a front part and a rear part based on a partition. The scum eliminating unit discharges floated materials at the upper side of the front part to outside. The slanted plate increases the area of water between the front part and the partition. The hopper and the sludge transferring pump discharges precipitates to outside. |
