FIELD: waste processing. SUBSTANCE: invention is aimed at anaerobically purifying waste water and processing carbon- nitrogen-containing household wastes with production of methane at individual farms being far-off from centralized heat and power supply systems and sewer systems. Biocultivator has a vertical frame with partitions of chambers for acidic, alkaline, and methane fermentation, and a stirring means positioned between charge and discharge fittings. A cylindrical-body dispergator is mounted before acidic fermentation chamber. A drive shaft with helical blades is placed along dispergator axis, the blades interacting with helical prominences fastened to inner side wall of dispergator body at an angle to helical blades. Frame bottom is perforated and connected with acidic fermentation chamber, whereas methane fermentation chamber is connected with section of biomethane/water separation made in the form of body with inclined partitions, which also has a water drain in its bottom part, explosive valve, and a biomethane discharge pipe with hydraulic gate in its upper part. EFFECT: improved design. |
