Study on Water Environment Capacity and Ecological Restoration in Lake Honghu of Hubei Province, China

The maximum COD
_Mn
, TN and TP inlet permits under different water quality target were calculated and simulated, based on Honghu wetland protection and ecological restoration planning. The current pollution load and water environment capacity of the Lake Honghu was analyzed. The target reduction amounts in different planning periods were determined based on the current pollution load. It provided technical guidance to the water pollution control for the lake valley. Finally, such countermeasures as the wetland ecological restoration and water network amend were presented to improve the water environment capacity of Lake Honghu.
