FIELD: waste disposal. SUBSTANCE: invention relates to anaerobically treating drains and processing carbon- and nitrogen-containing solid domestic wastes accompanied with production of methane in individual dwellings remote from centralized heat and power-supply networks. Plant contains vertical casing with horizontal partitions defining compartments for acid, neutral, alkali, and methane fermentation; shaft of stirrer with drive and blades. Compartments communicates with one another from loading unit to discharge unit. Plant is further provided with hydraulic gate and branch pipe for delivering methane to consumer. Settling section for solid constituent of postfermentation residue also has discharge pipe. Compartments are provided with perforated bottoms, wherein perforation size decreases in direction of substrate displacement from acid to methane fermentation compartment, and blades placed beneath bottoms are spiral-shaped to clean bottoms when stirring. When stirring is terminated, blades occupy upright position. EFFECT: improved structure. 2 dwg |
