摘要
为了考察汉中市区饮用水水源地水质状况,从汉中市区的三大饮用水水源地随机抽取15个居民饮用水点进行取样检测,通过研究水质的感官指标、有机物污染指标、溶解性总固体、酸碱度以及金属元素含量,并结合相关的问卷调查及样点环境特点进行水源地水质分析评价。分析结果表明,汉中市区三大水源地所取样品的全部检测指标合格率为86.7%,不合格项目主要集中在p H值、BOD5和TDS 3个指标上,所有区域样品在测重金属含量符合限值标准。这个结果能够为汉中市区饮用水水源地安全改造提供实践依据。
The15residents drinking water sites was randomly sampled from three major water sources in Hanzhong city,by analyzing the sensory index of water quality,organic matters pollution index,total soluble solids(TDS)?pH and heavy metal contents,and combining with relevant questionnaire survey and sample environment charac-teristics to conduct the water quality evaluation of drinking water sources.The results showed that the qualified rate of all the tested samples was86.7%,and the unqualified projects were mainly concentrated in three indexes of pH,B0D5and TDS.All the samples meet the limit values of heavy metals content.These can provide a practi-cal basis for safety transformation of drinking water sources in urban area of Hanzhong city.
