摘要 |
<p>A method for aerobically treating a low solids water-containing oily sludge and other organic wastes which comprises combining said sludge or waste with a biologically inert, non-friable bulking agent characterized by having a substantial component with a density less than water to form a mixture, passing an oxygen-containing gas through said mixture to separate excess water and form a high solids content reaction mixture, reacting said high solids content reaction mixture in the presence of an aerobic biomass under effective aerobic conditions to form a treated sludge and an active biomass-coated bulking agent component having a density less than water in said high solids content reaction mixture, separating said biomass-coated bulking agent component from said treated sludge or waste, and recovering said treated sludge or waste from said reaction mixture has been provided. <IMAGE></p> |
