Investigation and analysis of water environment characteristics in Taipu River

Taipu River is one of the important river channels of Taihu Lake, and also an important water body in the demonstration zone of green and integrated ecological development of the Yangtze River Delta. In this study, we collect the water quality monitoring data of Taipu River and related research results of Taipu River water quality, and analyze the water environment characteristics of Taipu River by analyzing the water quality status of Taipu River main stream and East Taihu Lake. The results indicate that from 2016 to 2018, the annual mean values of conventional indexes in main sections of the Taipu River main stream were maintained in Class II to III. The incoming water from the Taipu River mainly includes the East Taihu Lake and its tributaries. The water quality of the East Taihu Lake is superior to that of the Taipu River. The water quality of the Jinze section is mainly affected by the inflow from the East Taihu Lake. Increase the discharge under Taipu sluice to supply high-quality water, which can effectively guarantee the water quality of the section. Then we identify the main water environmental problems in Taipu River basin. The results of our analysis can provide support for the water ecological environment protection of Taipu River.
