Abstract

A water-blocking air-permeable modular constructed wetland capable of aerating intermittently includes an aerobic reaction zone, an anoxic reaction zone, a soil plant zone and an aeration pipe; and the aerobic reaction zone, the anoxic reaction zone and the soil plant zone are communicated in turn along a bottom-up water discharging direction, the aerobic reaction zone includes an air-permeable water-blocking layer and an air-insulating layer that are arranged at interval from inside to outside, and an aeration port of the aeration pipe is located in a cavity, enclosed by the air-permeable water-blocking layer and the air-insulating layer.
