Research Of Water Environment Improvement Scheme On Hilly Region Along The Changjiang River

Based on the planning of water environmental protection in hilly region along the Changjiang River, this paper mainly studies on the calculation methods of water environmental capacity and projects of water quality improvement.This paper takes Pukou City as an example. Near by the Changjiang River, this district has topography of high in the middle and low in south and north.This paper establishes hydraulics and water quality numerical models of Pukou area .Using the model of river network, the environmental capacity of inland waterway is calculated,and this dissertation focuses on the deep research of the two projects of water quality improvement. Using the model of Changjiang River,the environmental capacity of Changjiang River in Pukou is calculater and the tail water from the effluent plant is analysised.This research provide reasons for the planning of water environmental protection in Pukou.
