发布时间：2018-08-16 19:02
【摘要】：本论文通过对临安市范围内城镇共593个农村供水点的水质进行采样检测,了解2011-2102年临安市农村地区生活饮用水水质基本情况及枯水期和丰水期变化情况。希望通过本次研究为制定临安市农村地区生活饮用水相关措施积累数据资料、提供科学依据。 参照GB5749-2006《生活饮用水卫生标准》进行判定,对感官性状和物理指标、毒理学和一般化学指标等15个项目进行检测,结果如下： (1)pH值指标中,2012年枯水期(99.0%)的合格率高于丰水期(96.8%),同样高于2011年枯水期(96.3%),而其大多因为过碱而不合格。 (2)色度指标中,2012年的枯水期(92.7%)的合格率低于丰水期(98.3%),同样低于2011年枯水期(99.7%)。从调查的结果表明,2012年水体中色度的污染高于2011年。 (3)2012年临安生活饮用水的毒理学和一般化学指标在枯水期和丰水期没有差异,且2012年枯水期和2011年枯水期的合格率也没有差异。说明上述这段时间内临安市农村生活饮用水的毒理学和一般化学指标比较稳定。 对研究结果进行评价,得出如下结论： 1、丰水期的pH值指标合格率低于枯水期。 2、2012年枯水期水质污染程度低于2012年丰水期和2011年枯水期。 3、2011年～2012年临安市农村生活饮用水的毒理学和一般化学指标比较稳定。
[Abstract]:In this paper, the basic situation of drinking water quality in rural area of Lin'an city from 2011-2102 and the variation of low and high water supply period were studied by sampling and testing 593 rural water supply points in Linan city. It is hoped that this study will provide scientific basis for the establishment of relevant measures for drinking water in rural areas of Linan. The sensory and physical properties, toxicology and general chemical indexes of 15 items were determined by referring to GB5749-2006 's Sanitary Standards for drinking Water. The results are as follows: (1) in the pH index, the qualified rate in the low water period (99.0%) in 2012 is higher than that in the high water period (96.8%), and also higher than that in the low water period in 2011 (96.3%), but it is mostly unqualified because of excessive alkali. (2) in the chroma index, the low water period in 2012 is also higher than that in the low water period of 2011 (96.3%). The qualified rate (92.7%) was lower than that in the high water period (98.3%), and was also lower than that in the dry season of 2011 (99.7%). The results of investigation showed that the pollution of chroma in 2012 was higher than that in 2011. (3) the toxicological and general chemical indexes of drinking water in Lin'an in 2012 were not different in dry and high water periods. And 2012 dry period and 2011 dry period of qualified rate is no difference. It shows that the toxicology and general chemical indexes of drinking water in rural areas of Linan are stable. To evaluate the results of the study, The conclusions are as follows: 1. The qualified rate of pH index in high water period is lower than that in dry season. 2. The pollution degree of water quality in low water period in 2012 is lower than that in high water period in 2012 and in low water period in 2011. 3. The toxicology and general chemical indexes of drinking water in rural areas are relatively stable.
