<p>A plant for processing organic material (18) which contains liquid and solid phases (19, 20), has a separator (6) for separation of the contaminated liquid and solid phases (19, 20) from one another, the contaminated liquid phase (19) being conducted to a recirculator (52) connected to an anaerobic filter (30) for purification of the contaminated liquid phase (19). In addition to the contaminated liquid phase (19) the recirculator (52) also receives the liquid phase (41) purified in the anaerobic filter (30), so that the contaminated liquid phase (19) and the purified liquid phase (41) are mixed in desired proportions for introduction into the filter (30). The remainder of the purified liquid phase (41) is withdrawn and can be conducted to say a recipient. The contaminated solid phase (20) is conducted from the separator (6) to a biogas reactor and after stabilisation to a thickener/drier for conversion into a sludge (77) which is useful for landfilling, deposi tion, composting, fertilizing and like purposes. The liquid (78) remaining in the thickener/drier is conducted to the recirculator (52) for admixture with the mixture (40). The biogas (45, 73) generated in the anaerobic filter (30) and the biogas reactor, respectively, is collected for use.</p> |
