Intermittent aeration in constructed wetlands helps remove nitrogen and phosphorus from polluted water. By adding air to the water, the wetlands can clean the water better. The study used shale and T. latifolia plants in the wetlands to treat polluted water from the Jin River. Aeration improved the removal of ammonia-nitrogen, total nitrogen, soluble reactive phosphorus, and total phosphorus. However, it did not help with nitrate-nitrogen removal. The plants in the wetlands absorbed more nitrogen and phosphorus when aeration was used. Overall, intermittent aeration can enhance the efficiency of wetlands in cleaning up polluted water.
