| 成果简介 | NOVELTY - Invention relates to treatment of sewage sludge, particularly sludge-lignin of pulp and paper industry. Sludge-lignin is dehydrated by flotation. Current with density less than or equal to 0.01 A/cm2 is supplied to sludge-lignin, which is sufficient for destruction of part of hydrate layers on surface of sludge-lignin and formation of hydrophobic sections on them. Then, aeration is performed with oversludge water saturated with air or air. USE - Chemistry. ADVANTAGE - Dehydration of sludge-lignin without use of reagents with reduction of power consumption. 4 cl, 3 ex |
