ABSTRACT:
In a polluted water purifying method and apparatus, a purification treatment tank is filled with massive purifying members in a purifying region, each massive purifying member including plural opening portions having an equivalent diameter of 1 to 5 cm which are provided on the surface thereof, and plural interconnecting channels which intercommunicate with one another and provided inside of the members, and each opening portions continuously intercommunicating with at least one of the channels. Polluted water containing SS, BOD, etc. is supplied through the purifying region of the tank to be brought into contact with the massive purifying members. At the same time, oxygen-contained gas is jetted as fine bubbles at a predetermined interval from the bottom portion of the purifying region into the polluted water so that the stream of the flowing polluted water flowing in the purifying region, so that the fine bubbles of the oxygen-contained gas are contacted with the polluted water in a substantially perpendicular direction to each other, whereby an aerobic treatment and an anaerobic treatment are rapidly and efficiently performed on the surface of the purifying members and inside of the purifying members respectively.
