摘要
[目的]了解聊城市农村集中式供水工程的饮用水水质情况,为实施农村饮水安全工程提供依据。[方法]2008年,在聊城市所辖8个县(市、区)随机抽取113个供水监测点进行感官指标和一般化学指标、毒理学指标、微生物学指标检测。113处监测点均为地下水,水源为深井水的占83.18%,均未进行消毒处理。[结果]枯水期、丰水期各检测出厂水、末梢水113份,水样合格率枯水期为22.12%,丰水期为20.35%(P>0.05)。检测项目中,总大肠菌群、粪大肠菌群和细菌总数合格率,出厂水、末梢水均为枯水期高于丰水期(P<0.05);氟化物合格率浅井水高于深井水(P<0.05)。[结论]聊城市农村生活饮用水水质较差,微生物指标超标是影响水质的主要原因。
[Objective]To master drinking water quality of rural drinking water projects in Liaocheng city, and develop project planning for the safety of drinking water. [Methods] 113 monitoring sites, which distributing in 8 counties of Liaocheng city,were randomly chosen to investigate drinking water quality including sensory indexes, the general chemical index, toxicologieal index and microorganism index in 2008. All the samples were underground water,83. 18 % of which are deep layer underground water, and were not disinfected. [Results] 113 samples from effluent and tap water in dry season and rainy season were detected, whose eligible rate is 22. 12 % and 20.35 %, respectively（ P 〉0.05 ）. Among all the index being detected, the eligible rates of total coliforms, fecal coliforms and bacteria count were higher in dry season than in rain season（ P〈0.05）,and the eligible rate of fluoride was higher in shallow layer ground water than in deep layer ground water. [Conclusion]The drinking water quality in the rural area of Liaocheng city is at lower level and microorganism contamination is the major factor.
