The low oxygen concentration causes the oxidation decomposition rate of organic matters in the wetland system to be reduced, the nitration reaction is not thorough, and the removal of nitrogen in the wetland system is limited, and the blockage of the wetland system is mostly caused by the retention and accumulation of suspended matters and organic matters in sewage in the wetland system. Therefore, the key point that the purification capacity of the wetland system can be improved and the service life can be prolonged by sufficiently supplying oxygen is provided.
