ADVANTAGE - The system is environment-friendly, and has high processing efficiency, low cost, simple operation management and steady running.    DETAILED DESCRIPTION - A farm sewage processing system comprises hydrolysis acidification tank (1), upflow anaerobic sludge blanket tank (2), middle sedimentation tank (3), anoxic tank (4), biological contact oxidation tank (5), reaction tank (6), inclined sedimentation tank (7), vertical subsurface flow manual wetland (8), sludge concentration tank (9) and drying tank (10). The hydrolysis acidification tank is provided with composite biological filler (12) and cutting water pump (13) through sewage pipe (11). The anoxic tank and biological contact oxidation tank is set with liquid reflux pump through sewage reflux pipe, air inlet pipe and fan. The sludge concentration tank and hydrolysis acidification tank is set with sewage reflux pump, screw pump and frame filter press. An INDEPENDENT CLAIM is included for processing farm sewage comprising entering sewage into hydrolysis acidification tank, decomposing macromolecular organic matter with anaerobic/facultative anaerobic microorganisms to increase biodegradability, entering into upflow anaerobic sludge blanket tank, anaerobically processing to produce methane and carbon dioxide, entering into middle sedimentation tank, entering sludge sediments into sludge concentration tank through sludge pipe, entering into anoxic tank, removing ammonia and ammonium ion, entering into biological contact oxidation tank, infusing air, entering into reaction tank, adding flocculating agent and dispersant, forming suspension, continuously performing sedimentation, entering into vertical subsurface flow manual wetland, purifying until indexes are reached, circulating, dehydrating and drying sludge.
