<p>The plant comprises a fermentation chamber (4), a compensation chamber (6) and a final settling chamber (7) which are preferably joined into a construction assembly and thermically insulated, the fermentation chamber being provided with at least one inlet pipe and the compensation and settling chambers with at least one outlet. The particular shape of the compensation chamber (6) as well as the arrangement of the adjustable edge of the overflow-shoot (32) including the by-pass conduit (23) with gas and floating material separator (26) create the conditions required for further treating floating materials and discharging them. The arrangement of the final settling chamber (7) under, respectively beside, the fermentation chamber (4) generates the high hydrostatic pressure charge required for a better separation of micro-organisms of flowing fermentation residues. The settled outflow is directed to the outside (3) through a siphon pipe (11) provided with an overflow edge (42) in a common collector opened on the gas side to the compensation chamber (6) and having a discharge conduit in the form of a siphon (21) provided with a closure member. The deposited active sludge (micro-organism) is reintroduced at regular intervals from the settling chamber (7) into the fermentation chamber through one or a plurality of siphon conduits (12). According to the raw substrate to be treated, the path of the substrate in the fermentation container (1) is defined by the selection and arrangement of connection and conveying conduits (9, 10, 11, 12, 13). By providing an anaerobic filter (51) in lieu of the siphon (11), an improvement of the purification degree and an easy maintenance of the filter (51) by a washing integrated in the mixing system are obtained.</p> |
