湖州市太湖饮用水水源水质特征分析

Water quality evaluation is very important for the design and operation of water treatment and the water supply security. Based on the continuous monitoring and data analysis of the new drinking water source in Huzhou from 2014 to 2015, the pollution characteristics and temporal-spatial trends of Tai Lake source were investigated. The results showed that the representative water quality indexes of Tai Lake source met the standards of Class III for surface water in China, except for total nitrogen, phosphorus and iron. The water quality of five sampling sites which have different distance from the lakeshore had the similar temporal trends. The farther the distance from the lakeshore was, the more stable the water quality was. More attention should be paied to water eutrophication and seasonal accidental risk.
