为了解定西市安定区城乡居民生活饮用水质量,确保饮用水安全、卫生达标,对定西市安定区部分地方的生活饮用水进行水质常规分析项目的测定。从检测的12个水质指标可以看出,安定区城乡居民饮用水的色度、浊度、嗅和味、肉眼可见物均符合标准,合格率为100%;pH值在6.5-8.5之间,显弱碱性,亦符合饮用水水质要求;电导率、总硬度、碱度均有不同程度的偏高。城镇居民饮用水检测结果显示,水中氯化物含量以及化学耗氧量偏高;农村居民饮用水检测结果显示,水中氯化物含量以及化学耗氧量完全符合饮用水水质要求。
In order to understand the quality of drinking water in urban and rural areas of Anding District in Dingxi City and ensure the safety of drinking water and sanitary standards, the routine water quality analysis of drinking water in some areas of Anding District in Dingxi City was conducted. It can be seen from the detected 12 water quality indicators that the colorimetric, turbidity, smell and taste of the drinking water of urban and rural residents in Anding District are all in conformity with the standards, with a pass rate of 100%; the pH value is between 6.5 and 8.5, Significantly weak alkaline, also meet drinking water quality requirements; conductivity, total hardness, alkalinity have different levels of high. The test results of drinking water of urban residents showed that chloride content in water and chemical oxygen consumption were high. Drinking water test results of rural residents showed that the chloride content and chemical oxygen demand in water fully met the drinking water quality requirements.
