Said re-aeration device includes re-aeration pipe and windmill. Said re-aeration pipe has a tubular structure with openings at both ends; one end inserts the wetland substrate, and the other end connects with the windmill for receiving and accelerating airflow. The re-aeration pipe may also contain several telescoped or parallel arranged pipes with openings at both ends as well as with different pipe diameters and lengths, which connects with windmill to form said re-aeration device. This invention also provides a method of re-aeration for constructed wetlands by using above-mentioned device. The re-aeration device provided by this invention has features of simple structure, environmental material, and low-cost. The re-aeration method provided is characterised as simple, practicable, energy-efficient, environmental, low-cost, widely applicable, and has good effect, high performance on re-aeration.6/6 1 1 4-1- 4-2 6-1 2 6 5 6 E [] ED E: EOl - -l - jC Figure 7
