REAERATION DEVICE AND REAERATION METHOD FOR CONSTRUCTED WETLAND

摘要

A reaeration device for a constructed wetland comprises a reaeration pipe (2) and a windmill (1). The reaeration pipe (2) is of a tubular structure with two ends opened. One end of the reaeration pipe (2) is inserted into a wetland substrate, and the other end of the reaeration pipe (2) is connected to the windmill (1) and is used for receiving and accelerating an air flow. The reaeration pipe (2) can be formed by combining multiple inner pipes (6). The inner pipes (6) of different pipe diameters and lengths are sleeved and stacked coaxially or arranged in parallel. Also provided is a method for performing reaeration of constructed wetland by using the reaeration device. The reaeration effect is good, and the operation efficiency is high.
