Xinhai Phase I constructed wetland is located on the low bank of the right bank between Xinhai Bridge and Dahan Bridge. In 2003, a wetland sewage drainage demonstration site was constructed from the lower bank of Dahan Creek downstream of Xinhai Bridge. every day). The site area was originally designed for 8 hectares, and the total area now reaches 11 hectares. Different treatment sections draw water by gravity, and the sewage begins to flow into the first dense planting area as the solids settled in the primary sedimentation tank, mainly planting Da'an water chestnuts, reeds, and cattails. The nitrifying bacteria are the dominant species in the cultivation, and the nitrification is performed in the open water, and then introduced into the second dense planting area for the denitration. With a residence time of 6 days, the organic matter, suspended solids, and high nitrogen content in the sewage are passed through the three-stage artificial wetland to reduce pollution and improve the water quality of Dahan Creek. In Xinhai Phase I constructed wetland, the average water temperature is between 18.7 and 30.3 degrees Celsius, which is mainly affected by the intensity of sunlight. The pH value of the water quality in the treatment unit area is between 7.8 and 7.9, and the pH value of the water quality in the drainage pool is between 6.7 and 10.3. The dissolved oxygen in the drainage water is in a supersaturated state due to the vigorous photosynthesis of algae and aquatic plants. -- Wikipedia
