Abstract:

In order to protect the water environmental quality of Huaihua City and provide scientific basis for the construction of ecological livable city of Huaihua, the author made a field investigation and monitoring of water quality of Taiping River of Huaihua City, which was divided into mean and dry water periods. The author also made a comprehensive evaluation of water quality with the monitoring data of the past years of Taiping River. The results showed that the content of TP and NH3-N of each section was high, which all exceeded the state V water quality standard. The content of DO in water was low. Some section did not reach IV water quality standard and some even did not reach V water quality standard. Wantan section had a higher content of TP and NH3-N than Chenjia section, which explained the pollution of Taiping River had a certain effect on the water quality of Wushui River. Combined with the monitoring data of the past years of Taiping River, the author found that the content of DO in water decreased continuously, and the content of TP increased continuously. The water pollution was increasingly serious. Therefore, further management of Taiping River is very important to the protection of Wushui River and the construction of ecological livable city of Huaihua.
