广西城市供水水质饮用特征的流域地域分布与差异

Watershed and geographical distribution of drinking water quality characteristics and differences in the cities of Guangxi

广西城市水源水的水质特征决定了供水水质的饮用特征,通过对广西主要城市供水水质的饮用特征性指标的全年表现和不同流域地域的比较研究,得到广西城市供水水质的流域地域饮用特征主要呈现为:西江水系流域城市酸碱度偏碱,桂南和沿海诸河流域城市酸碱度偏酸;硬度和溶解性总固体在不同流域地域城市中存在明显的差异性,西江流域城市稍高,桂南和沿海诸河流域城市略低;硫酸盐、氯化物指标在各流域地域城市中保持了较低的水平。结果表明,广西城市供水的饮用特征继承了原水水质中良好的天然特性,其饮用品质和口感俱佳,是广西城市成为宜居城市的基础性条件,值得倍加珍惜和维护。

Drinking water quality characteristics were determined by watershed and geographical characteristics in the cities of Guangxi through the annual performance indicators of drinking water quality characteristics in the major cities of Guangxi and comparative study of different watershed area, the drinking water quality characteristics of the watershed area in the cities of Guangxi were mainly characterized. The cities in Xijiang River system showed alkaline pH, and the cities in Guinan and coastal river basins showed acidic pH. The hardness and total dissolved solids existed obvious differences in different watershed and geographic cities. The Xijiang River cities were higher, and Guinan and coastal rivers basin cities were lower. The sulfate and chloride indicators maintained a lower level in various watershed cities. It indicated that the characteristics of drinking water supply in Guangxi inherited good natural characteristics of source water quality, the quality and taste were better. It is the basic condition that the cities of Guangxi becomes livable. It is worthy to cherish and maintain.
