Summary: | The invention discloses a flood season rainwater treatment method in a subsurface flow constructed wetland system. The method includes the steps: (1) additionally forming rainwater overflow openings in partition walls among subsurface flow constructed wetland cells and braiding channels, enabling the rainwater overflow openings to be higher than surface layers of subsurface flow constructed wetland body filler areas, and determining the number N of the rainwater overflow openings in the cells according to average flood season rainfall P of a subsurface flow constructed wetland building land and monomer areas A of the cells; (2) additionally forming rainwater percolation collection openings in longitudinal partition walls of the cells of two peripheral sides of a subsurface flow constructed wetland and the peripheral partition walls of the braiding channels. The rainwater percolation collection openings comprise percolating tanks and rainwater inlet pipes, the rainwater inlet pipes arearranged at the bottoms o |
