The air inlet pipe is arranged above the partition 6, one end of the air distribution pipe 1 is connected to the air inlet pipe, and the other end of the air distribution pipe 1 is connected to the drainage chamber 51. After the tail gas of the sewage treatment equipment is collected, it enters the contrived wetland with reduced blockage of the present application through the air inlet pipe and passes into the drainage chamber 51 through the air distribution pipe 1. The gas in the drainage chamber 51 rises and provides sufficient oxygen and nutrients to the matrix layer 2, thereby improving the wetland treatment function and reducing the blockage of the wetland. The matrix layer 2 is arranged above the air inlet pipe. The water distribution pipe 3 is arranged above the matrix layer 2.

[0030] Among them, the present application arranges the air intake pipe, the matrix layer 2, the water distribution pipe 3, the drainage pipe 4 and the partition 6 and other accessories in the installation barrel 5, so that the artificial wetland of the present application can be mass-produced from the factory. When installing on site, it is only necessary to install multiple installation barrels 5 on the ground and splice them, and connect the drainage pipes 4 between multiple artificial wetlands through short pipes, so as to achieve large-scale rapid installation on the construction site.
