Abstract:
     Going through such technological steps as collecting waste water, separation of solid from liquid, anaerobic fermentation, generation of marsh gas, sewage exhaust, dewatering solid excrement and mud, addition of compost ferment, stirring, addition of materials, breaking and packing, an organic fertilizer is obtained. the marsh gas is passed via control unit and carburetor to engine that drives an electric generator. Aerobic digestion and mud dewatering machine are unnecessary. The compost ferment can accelerate the decomposition of NH3-N, so not having adour.
