摘要
通过对南宁市两个水源点2007—2009年监测数据的统计分析,得出邕江水源的自然水质特征和污染指标表现情况。结果表明,邕江原水的自然水质特征主要表现为浊度受季候水期影响较大,水的酸碱度为中性略偏弱碱,硬度适中;粪大肠菌群指标对邕江水源水质状况影响最大,近年来邕江水源的水质总体上保持稳定,未出现劣变的趋势。
The natural water quality and contamination index data of the Yongjiang River source water were obtained by statistic analysis of the data from two monitoring points in Nanning City from 2007 to 2009. The result indicated that seasonal phonological periods had more influence on turbidity of the water of the Yongjiang River with a weak alkali mild hardness. The index of fecal coliform had great impact on source water quality. In recent years, the water quality in Yongjiang River kept stable and there was no tendency of deterioration.
