[0034] The present invention will be further explained below in conjunction with the drawings: Figure 1-3 As shown, an ecological slope protection type sewage land infiltration system includes a grid pool 2, an anaerobic hydrolysis pool 4, and a stepped land infiltration unit arranged in order from top to bottom along the slope of the slope. The grid pool 2 Connected to the ditch 1, the stepped land infiltration unit includes a multi-stage slope protection infiltration bed 5, the slope protection infiltration bed 5 is filled with a filter material 7, and a wet plant community 9 is cultivated on the slope protection infiltration bed 5, adjacent Between the slope protection infiltration beds 5, a modal conversion component 6 for controlling the infiltration rate, hydraulic retention time, the environment in the filter layer, and the water outlet mode is arranged.
[0035] The modal conversion assembly 6 includes an inverted T-shaped tube 11, an interface at the lower end of the in...
