用水源地水质安全预警保护措施 环境工程专业VIP专享VIP免费

摘要我国人均水资源极度匮乏，随着社会经济的快速发展，人民生活水平的提高，对淡水资源的需求也越来越大，尤其是对饮用水的水质安全提出了更高的要求。随着近几年饮用水源地事故的频繁发生，群众对水源地水质安全也愈加重视，苏州的饮用水取水口基本都在太湖，如果太湖水质受到污染，整个苏州人民的饮用水都将受到影响。所以，苏州工业园区开辟了阳澄湖水源地，形成“双水源”供水格局，保障园区人民的饮用水安全。本文主要通过近几年对阳澄湖的监测，分析苏州工业园区阳澄湖水源地的水质安全情况，得出通过政府近几年努力，苏州工业园区阳澄湖水源地水质类别总体保持稳定，富营养化指标总体又不显著下降，仍需持续关注。本论文还分析了降水和面源污染对水源地水质的影响，同时结合大气中的氮氧化物，分析了大气中氮沉降对水源地中氨氮的影响。此外还针对上游来水与水源地水质比较分析来水影响。同时对于阳澄湖最近的特殊情况作出了分析。最后针对阳澄湖现状，提出了合适的预警体系，给予保障苏州工业园区阳澄湖水源地水质工作一定的参考。关键词：饮用水源地，水质安全，预警，保护措施IAbstractChina’sfreshwaterresourcespercapitaisextremelyscarce.Withtherapiddevelopmentofsocialeconomy,people’slivingstandardsgraduallyimprove,thedemandforfreshwaterresourceisbecomingmoreandmorebig,especiallyputsforwardhigherrequirementsonthewaterqualitysecurityofdrinkingwater.Asthesourceofdrinkingwaterinrecentyears,accidentsoccurfrequently,thecrowdismoreandmoreattentiononwaterqualitysecurity,basicinTaihuLake,SuzhouwaterintakeifthepollutionofTaihulakewaterquality,thewholeSuzhoupeople'sdrinkingwaterwillbeaffected.So,Suzhouindustrialpark,openedtheYangchengLakewatersource,formapatternofdualwatersupply,thedrinkingwatersafetyofpeopleinthepark.ThispapermainlythroughthemonitoringofYangchengLakeinrecentyears,theanalysisofSuzhouindustrialpark,YangchengLakewatersourcewaterqualitysafetysituation,itisconcludedthatthroughthegovernmenteffortsinrecentyears,Suzhouindustrialpark,YangchengLakewaterqualitycategoriesgenerallystable,eutrophicationindexwithoutasignificantreductioninoverall,stillneedtocontinuetofocuson.Thispaperalsoanalyzedtheprecipitationandtheinfluenceofnon-pointsourcepollutiononwaterquality,atthesametimecombinedwithnitrogenfromtheatmosphere,analyzedtheatmosphericnitrogendepositionontheeffectofammonianitrogeninthewater.Andalsoforinfluenceofcomingwaterfromtheupperstreamcomingwaterandwaterqualityanalysis.AtthesametimemadeananalysisforthespecialcaseofYangchengLakerecently.Finally,inviewofthepresentsituationofYangchengLake,andputsforwardappropriateearlywarningsystem,protectionofSuzhouindustrialpark,yangchenglakewaterqualityreferencework.Keyword:drinkingwatersourcearea,watersecurity,safetywarning,protectionmeasuresII目录摘要............................................................................................................................................IAbstract.....................................................................................................................................II目录..........................................................................................................................................III第一章绪论...............................................................................................................................11.1研究背景及意义..............................................................................................................11.2拟采取的研究方法和技术手段................................................
