Ecological ditch deep aeration composite artificial wetland system

The utility model discloses a deep aeration composite artificial wetland system for an ecological ditch. The deep aeration composite artificial wetland system consists of an ecological ditch aeration oxygenation system and a subsurface flow artificial wetland system, sewage is subjected to deep oxygenation and aeration treatment through a plurality of ecological ditch aeration oxygenation systems, and then is vertically and uniformly distributed through water distribution holes to enter the composite constructed wetland system, so that the nitrification and denitrification effects of the system are enhanced, the removal efficiency of pollutants in unit area of the constructed wetland is improved, and the comprehensive purification capacity of the constructed wetland system is enhanced in a limited space; and the occupied area of the constructed wetland system is saved. 本实用新型公开了一种生态沟深度曝气复合人工湿地系统，由生态沟曝气增氧系统和潜流人工湿地系统两部分构成。污水经过多条生态沟曝气增氧系统深度增氧曝气处理后，通过布水孔垂直均匀布水进入复合人工湿地系统，强化了系统的硝化与反硝化作用，提高人工湿地单位面积污染物去除效率，在有限的空间内增强人工
