NOVELTY - Biomembrane automatic aeration vertical underflow type artificial wetland sewage processing device comprises biochemical processing pool (I), automatic aeration pool (II), artificial wetland processing pool (III), and siphoning filter pool (IV). A fiber film material (2) construction is arranged in biochemical processing pool and is planted with emergent aquatic plant. A waterwheel is arranged at upper part of automatic aeration pool. The water output pipe of water pump arranged at bottom of the pool is communicated with water distribution pipe in artificial wetland processing pool.    USE - Biomembrane automatic aeration vertical underflow type artificial wetland sewage processing device for sewage processing and river wastewater processing of towns, outskirts, villages and countries.    ADVANTAGE - The processing device has high contamination load, strong impact resistance, small floor area, high processing efficiency, stable operation and low energy consumption.    DETAILED DESCRIPTION - Biomembrane automatic aeration vertical underflow type artificial wetland sewage processing device comprises biochemical processing pool (I), automatic aeration pool (II), artificial wetland processing pool (III), and siphoning filter pool (IV). A fiber film material (2) construction is arranged in biochemical processing pool and is planted with emergent aquatic plant. A waterwheel is arranged at upper part of automatic aeration pool. The water output pipe of water pump arranged at bottom of the pool is communicated with water distribution pipe in artificial wetland processing pool. The artificial wetland processing pool is combined by compound substrate layers. The clean water outlet is communicated with siphoning filter pool. Filter fillers are arranged in siphoning filter pool. The flow guide funnel on top of siphoning filter pool is communicated with water outlet pipe.
