摘 要：As the development of city economy,Zhongdong River in Hangzhou was seriously polluted,with the worst water *** order to obtain the effect of water diversion and distribution from Qiantang River on the water quality of Zhongdong River,7-year continuous monitoring was conducted,which was at the fixed stations before and after the water diversion and *** the water diversion project,the dissolved oxygen concentration of the river water was one to two times higher than before,and the ammonia nitrogen and total phosphorus decreased by 60%and 65%,*** increased the amount of water diversion,the dissolved oxygen concentration of the river water elevated by 13%,and the ammonia nitrogen,total phosphorus and potassium permanganate index decreased by 8%,3%and 14%,*** reason for the river water pollution was contributed to the combined sewer system and riverway sludge,especially during the rainfall,the dissolved oxygen concentration of Zhongdong River sharply declined by 95%,while the ammonia nitrogen and total phosphorus increased by 90%and 87%,*** research results could provide theoretic basis for sustainable improvement of Zhongdong River water quality and river management department making the related regulations and policies.
