NOVELTY - Sludge compost system comprises sludge dewatering device, two fermentation cabins (1), and internal ferment sludge delivery mechanism (2). The fermentation cabin is set with air outlet (12) with sludge separating frame (3). The sludge separating frame for fermentation storehouse is divided into fermentation cavity and discharging cavity. The discharge cavity side wall is set with air inlet (11). The air outlet of first fermentation chamber through air inlet port is connected to second fermentation chamber. An air pump (4) is connected to air outlet pipe.    USE - Sludge compost system.    ADVANTAGE - The system reduces sludge treatment time and cost, reduces composting times and increases quality.    DETAILED DESCRIPTION - Sludge compost system comprises sludge dewatering device, two fermentation cabins (1), and internal ferment sludge delivery mechanism (2). The fermentation cabin is set with air outlet (12) with sludge separating frame (3). The sludge separating frame for fermentation storehouse is divided into fermentation cavity and discharging cavity. The discharge cavity side wall is set with air inlet (11). The air outlet of first fermentation chamber through air inlet port is connected to second fermentation chamber. The second fermentation chamber through air inlet port is connected to first fermentation chamber. An air pump (4) is connected to air outlet pipe. The sludge separating frame comprises supporting rotating shafts which rotates in fermentation cabin from left side to right side horizontally. The shaft is provided with support bracket. The support rotate shaft is set with interaction gear and gear mesh. The first root support rotating shaft through transmission mechanism is connected with driving motor.
