包头市是内蒙古自治区实力最强!基础设施条件最好!规模最大的城市;作为 内蒙地区的工业重镇,拥有全区最大的工业基地和商品市场,具有相对雄厚的工业 基础和综合性加工工业基础西部大开发为包头市在新世纪的快速发展提供了良机, 然而,作为制约西部大开发的一个重要因素一水资源短缺,同样会成为包头市今后 发展必须面临和解决的问题 包头市属北方严重缺水城市一方面,城市缺水,另一方面每天都有大量的饮 用水用于冲厕所及城市杂用水,为了充分利用水资源,建立节水型城市,政府决定 对新建大型居住小区进行分质供水,明日星城做为包头市旧城改造和经济适用住房 的样板小区,项目建设规划一期建筑面积45万平方米,二期建筑面积50万平方米, 200余栋建筑,小区人口将超过4万,将小区生活污水排入西郊污水处理厂,利用 处理后的中水回用来冲厕所!小区绿化!洗洒道路及景观用水 5内蒙古自治区包头市水资源调查评价与规划6指出:要坚持水资源开发与保 护!节流并重,保护与节流优先的原则,合理配置包头市水资源,做到水资源的高 效利用,污水的再生回用,从而达到社会!经济和生态效益的统一通过对城市用 水现状分析,认为污水再生回用作为污水资源化的重要体现形式是解决水资源短缺! 实现水资源可持续开发利用的重要途径除了实施水资源保护和节流具体措施外, 一项非常重要的开源工程就是5西郊污水处理厂污水再生回用工程6,该工程除可改 善河流水环境外,还可为污水厂周边的明日星城居住区提供工业!市政杂用,城市 绿化用水及紧邻明日星城居住区的青年路绿化带生态建设的灌溉用水 通过合理开发和利用再生水资源,一方面体现了水的/优质优用,低质低用0原 则;另一方面也有利于提高城市水资源利用的综合效益污水再生利用是解决包头 水资源短缺的重要途径具有十分重要的战略意义 5西郊污水处理厂污水再生回用工程可行性研究6主要的工作内容包括:资料 收集!现场调查,分析包头市城市供水用水现状,研究用水供需平衡分析确定西郊西安建筑科技大学硕士报告 污水厂回用的领域与范围;确定再生水回用于不同领域的水量!水质及工程方案; 确定西郊污水厂污水再生处理系统的工艺方案;进行再生水回用管道系统的方案设 计;完成工程投资估算等 关键词:城市污水;再生利用;水资源;可行性西安建筑科技大学硕士报告 Afcas汤汤灯stodyonwast.即aterreuseen咖ecring ofBaotoucity街iaowaste恤atmentPlant sPccia舫ty二M切山cipalEngineering Graduatcsyudent:You兀aoyan T恤tor:GaoyUFeiProfessor ABSTRACT BaotouCity15thebiggesteityinseaie,themoststro吧eeono而epowerofInner MongoliarAutonomousRegion.AstheAutonomousregion,5eaPitaleity,BaotouCity havetheeomParetivelystrongerindustrybase.DeveloPmeniofWestRegionProvidedthe goodoPPoriUnityforit,sfl巧tdevel叩mentinneween址以however,asanimPo比劝t 几cto几waterresourcesmissing15restrictingthedeveloPmeniofthewestemregion,the same15beeom吨theProblemwehavetofaceandmustberesolvedinthefu奴ire develoPment.
