PURIFICATION OF EFFLUENTS AND INSTALLATION TO THIS END |
摘要 |
FIELD: process engineering.SUBSTANCE: set of inventions relates to treatment of effluents. Effluents are purified by anaerobic processing of primary sediment (PS) in tank for wastes (5) and separate processing of pasty excess sludge ("?"S). Said pasty excess sludge ("?"S) is pre-separated from primary sediment (PS) and fed to reactor of hydrolysis (8) wherein it is loosened and liquefied by thermal and/or chemical hydrolysis. Produced hydrolysed excess sludge ("?"S) is subjected to anaerobic processing irrespective of primary sediment (PS) in anaerobic reactor (14) communicated directly or indirectly with outlet of hydrolysis reactor (8). Pipeline (2) for feed of heat carrier fluid is arranged between hydrolysis reactor (8), preferably decompression tank (11) and purification tank (1) for primary sediment (PS).EFFECT: higher yield of biogas and methane.23 cl, 4 dwg |
