A Research Of Water Environment Protective Planning Of Zhangjiagang City

Recent years, the economy in Zhangjiagang city has got a rapid progress, following with the speedly development of industry, agriculture and city-planning construction, irrational collocation of water resource has deteriorated the water quality of river-network. Together with the feature of tidal river-network that water is shallow, velocity is slow and flow direction is indefinite, the problem of aquatic environment pollution has tended to be more serious,which strongly impacts on the daily life of riverains residents.In order to improve the aquatic environment of Zhangjiagang city, we should advanced sewage disposed rate to control contamination. On the other hand, consider with the advantage that the city abuts on Yangze River, we make research for different ways of improving the aquatic environment by piloting water. To improve the aquatic environment and increase the environmental capacity, this dissertation focuses on the deep research of the method of piloting water and also a quantitative analysis of the way of obstructing contamination. Based on the content mentioned above, the dissertation puts forward the direction of disposal and the detailed scheme of hydraulic engineering construction and attemperation. This research has great significance that it provides the theoretical fundament for solving the problem of aquatic environment of Zhangjiagang City.
