2008-2012年广西农村饮用水总硬度监测结果分析

Analysis on Total Hardness of Drinking Water in Guangxi Rural Areas in 2008-2012

摘要

摘要:
目的了解广西农村生活饮用水水质总硬度的含量及其分布状况。
方法对2008-2012年广西农村生活饮用水不同水源类型饮用水的总硬度含量及分布进行描述和分析, 检测结果按照《生活饮用水卫生标准》(GB 5749-2006) 进行评价, 数据资料通过Excel 2010和SPSS 17.0进行汇总分析。
结果广西农村饮用水以极软水和软水为主, CaCO₃浓度低于150mg/L比例高达60.20%;其次为中硬水占36.89%, 硬水、高硬水和超高硬水比例很少。在不同水源类型中, 地表水以软水为主, 地下水则以中硬度水为主。
结论广西农村饮用水总硬度水平较低, 以软水为主, 需加强总硬度对健康影响及相关干预措施的研究。

Abstract:
Objectives To understand the content and distribution of the total hardness of drinking water in Guangxi rural areas.
Methods The content and distribution of total hardness of drinking water in Guangxi rural areas was described and analyzed, and the test Results in 2008-2012 were evaluated according to the Health Standard for Drinking Water (GB 5749-2006), the data were analyzed by Excel 2010 and SPSS 17.0.
Results Most of drinking water in Guangxi was very soft water and soft water. The soft water with a concentration of CaCO₃ below 150 mg/L accounted for 60.20%; mid-level hard water accounted for 36.89%, and the normal-level and high-level as well as super-high level hard water were rare. Surface water was mainly presented as soft water while groundwater was mainly presented as mid-level hard water from different water source in Guangxi.
Conclusions The total hardness of drinking water in Guangxi was quite low, mainly presented as soft water. Research on the effect of water hardness on people's health together with associated interventions should be strengthened.
