【摘要】:本論文通過對臨安市范圍內(nèi)城鎮(zhèn)共593個(gè)農(nóng)村供水點(diǎn)的水質(zhì)進(jìn)行采樣檢測,了解2011-2102年臨安市農(nóng)村地區(qū)生活飲用水水質(zhì)基本情況及枯水期和豐水期變化情況。希望通過本次研究為制定臨安市農(nóng)村地區(qū)生活飲用水相關(guān)措施積累數(shù)據(jù)資料、提供科學(xué)依據(jù)。 參照GB5749-2006《生活飲用水衛(wèi)生標(biāo)準(zhǔn)》進(jìn)行判定,對感官性狀和物理指標(biāo)、毒理學(xué)和一般化學(xué)指標(biāo)等15個(gè)項(xiàng)目進(jìn)行檢測,結(jié)果如下: (1)pH值指標(biāo)中,2012年枯水期(99.0%)的合格率高于豐水期(96.8%),同樣高于2011年枯水期(96.3%),而其大多因?yàn)檫^堿而不合格。 (2)色度指標(biāo)中,2012年的枯水期(92.7%)的合格率低于豐水期(98.3%),同樣低于2011年枯水期(99.7%)。從調(diào)查的結(jié)果表明,2012年水體中色度的污染高于2011年。 (3)2012年臨安生活飲用水的毒理學(xué)和一般化學(xué)指標(biāo)在枯水期和豐水期沒有差異,且2012年枯水期和2011年枯水期的合格率也沒有差異。說明上述這段時(shí)間內(nèi)臨安市農(nóng)村生活飲用水的毒理學(xué)和一般化學(xué)指標(biāo)比較穩(wěn)定。 對研究結(jié)果進(jìn)行評價(jià),得出如下結(jié)論: 1、豐水期的pH值指標(biāo)合格率低于枯水期。 2、2012年枯水期水質(zhì)污染程度低于2012年豐水期和2011年枯水期。 3、2011年~2012年臨安市農(nóng)村生活飲用水的毒理學(xué)和一般化學(xué)指標(biāo)比較穩(wěn)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.
