2016-2017年广州市农村生活饮用水pH值等指标分析
|
摘要
目的了解2016-2017年广州市农村饮(改)水点pH值、浑浊度、总硬度、氯化物和溶解性总固体的含量,并探讨各指标之间的相关性。方法 2016和2017年分别选取广州市农村饮(改)水点57和49个,在每年的丰水期和枯水期采集出厂水,检测以上5个指标,按照《生活饮用水卫生标准》(GB 5749-2006)进行评价。结果 pH值、浑浊度、总硬度、氯化物和溶解性总固体指标的合格率分别为76. 06%、77. 93%、100. 00%、100. 00%和100. 00%。PY、NS和ZC三区pH值的合格率分别为10. 00%、33. 33%和56. 00%; ZC、CH、HD三区浑浊度的合格率分别为44. 00%、64. 00%和98. 00%。pH值与总硬度、溶解性总固体的相关系数分别为0. 270、-0. 325,总硬度与浑浊度、氯化物和溶解性总固体的相关系数分别为-0. 362、0. 536和0. 268,浑浊度与氯化物、溶解性总固体的相关系数分别为-0. 500、0. 370。结论广州市农村饮(改)水点pH值和浑浊度的合格率较低,相关指标之间存在相关关系,各区应结合实际情况加强农村饮水安全卫生管理。
Objective To detect the pH value,turbidity,total hardness,chloride,and total dissolved solids content of rural drinking( changing) water in Guangzhou from 2016 to 2017,and to explore the correlation between those indices. Methods A total of 57 and 49 rural drinking water point were selected respectively in 2016 and 2017. Chlorinated water was collected in annual wet season and dry season,and the above five indicators were tested according to the Hygienic Standard for Drinking Water( GB 5749-2006). Results The qualified rates of pH value,turbidity,total hardness,chloride,and total dissolved solids were 76. 06%,77. 93%,100. 00%,100. 00%,100. 00% respectively. The qualified rates of pH value in PY,NS,ZC were10. 00%,33. 33%,56. 00%,while the qualified rates of turbidity in ZC,CH,HD were 44. 00%,64. 00%,98. 00%. The correlation coefficient between pH value and total hardness,total dissolved solids were 0. 270,-0. 325 respectively. The correlation coefficient between total hardness and turbidity,chloride,total dissolved solids were-0. 362,0. 536 and 0. 268. The correlation coefficient between turbidity and chloride,total dissolved solids were-0. 500,0. 370. Conclusion The qualified rates of pH value and turbidity in Guangzhou rural drinking water point were low,and there is a correlation between relevant indicators. All districts should enhance the hygienic management of rural drinking water according to local situation.
