Analysis of Influence of Estuary Artificial Wetland on Water Environmental Capacity

Abstract:

The model of artificial wetland is designed using the data of hydrology and water quality, to analyze influence of estuary wetland on water environmental capacity in Yangguan-river. The change of concentration of COD and TN is simulated by inputting the model to FEFLOW software. Environmental capacity is calculated on condition that sewage plant is discharging upstream. The result shows that, water quality and environmental capacity are improved by wetland. Environmental capacity of COD can meet the water quality target, but TN cant meet the target because of the high background concentration. This conclusion can be used to formulate or modify the environmental protection and plan.
