<p>PURPOSE:To compact an installation by subjecting waste water to oxidation treatment while discontinuously exerting pressure on suspended microorganisms. CONSTITUTION:Waste water such as living waste water and hotel waste water is heated to 5-40 deg.C and pressurized at 0.1-10kg/cm<2>.G for 1sec-5min in a pressurized reaction tank. Waste water is treated with activated sludge while performing this operation three or more times per 1hr. Thereby treatment capacity can be maintained at a high level for a long period.</p> |
