What brings 5 billion cubic meters of water from south to south Henan branch network — people’s net-海思k3v2

What 5 billion cubic meters of water? – Henan – people.com.cn original title: what 5 billion cubic meters of water? South to North Water Diversion Project water since the 600 days, water 50 billion cubic meters, for Beijing Tianjin Hebei Henan 4000 million residents. With a drink of water, the day before from the water source of middle line of 30 representatives of the masses into Beijing, water saving and water masses, experts talk about "water, water". Through the past two years, along the south to North Water Diversion Project to bring what? The water quality is better, safer water supply water right now "!" In Hexi area Blue Water Park District, Cui Xiufang Boyle told delegates: "before a strange Tianjin, tap water pickled vegetables. When eating water, bitter and astringent, even the tea can not rush." "Little water!" Live in Beijing Fengtai District Jianxinyuan Si Li resident Liu Suxiang, who took the kettle: "look, this pot a month without brush, no scale." South hydrolysis thirst, receiving the people feel the most direct is the quality is good, the scale less. Data show that the water quality of Danjiangkou reservoir for many years to reach the second class of stable source. According to the monitoring of Beijing city tap water group, use water, tap water hardness by 380 milligrams per liter to 120 mg – 130. "Danjiangkou Water of low hardness, weak alkaline, good taste than water." Guogongzhuang water technical personnel. The change in water supply pattern. "The Beijing bid farewell to a single water predicament, center city water supply safety coefficient increased from 1 to 1.2." Beijing South Office Director Sun Guosheng introduction, the current urban water supply more than 70% on the south, directly benefit residents reached 11 million. By 2020, Beijing will achieve the Miyun reservoir, underground water and water diversion "Sanshui FBI, water is mainly used for city life, provide water for 20 cities and Metro city center tap water plant, water covered area of Beijing plain, the benefit of a population of 20 million. Tianjin Municipal Water Affairs Bureau deputy inspector Liu Changping said, as of now, Tianjin added 1 billion 60 million cubic meters of water, more than half of city residents eat water, from the "single Yinluan" into a "double water protection", equivalent to an increase of a water lifeline, city water supply dependence, single and vulnerability "contradictions be resolved effectively. Water conservation, water conservation priority is not "capricious" water receiving water adhere to the water conservation priority not easily won, and the water is not willful". Sun Guosheng introduction, Beijing, volume of water line to drink, deposit and compensation "principle, to the tune of 1 billion 580 million cubic meters of water, to meet the" drink ", 70% tap water supply plant for city living water; in addition to" save ", the 200 million cubic meters of water to the Miyun reservoir, Huairou reservoir, Ming Dynasty Tombs and Daning storage reservoir reservoir, an important role in the allocation of water resources in Beijing; and the" fill "for groundwater recharge. Beijing strict water pipe, tighten the tap, the city last year with 78 thousand sets of water-saving appliances. Use of recycled water, more than 70% of Beijing lake and river water from recycled water, recycled water accounted for 14 of the total water last year, become stable)

50亿立方米南水带来什么?–河南分网–人民网 原标题:50亿立方米南水带来什么?   南水北调中线一期工程通水以来,600多天,调水50亿立方米,惠及京津冀豫4000多万居民。同饮一江水,日前来自中线水源地的30名群众代表走进京津,与受水区群众、专家共话“调水、用水、节水”。   通水近两年,南水北调给沿线带来了什么?   水质变好了,供水安全更有保障   “现在的水好了!”在天津市河西区蓝水园小区,崔秀芳大妈对代表们说:“以前天津一大怪,自来水腌咸菜。小时候吃的水呀,又苦又涩,连茶都没法冲。”   “水碱少了!”家住北京丰台区建欣苑四里的居民刘素香,拿出烧水壶现身说法:“看,这壶一个月没刷了,也没啥水垢。”   南水解“渴”,受水区百姓最直接的感受是水质好了、水垢少了。数据显示,源头丹江口水库水质连续多年稳定达到Ⅱ类。据北京市自来水集团监测,使用南水后,自来水硬度由每升380毫克降至120―130毫克。“丹江水硬度低、偏弱碱性,口感要比地下水好。”郭公庄水厂技术人员介绍。   供水格局也在改变。“北京由此告别单一水源困境,中心城区供水安全系数由1.0提升至1.2。”北京市南水北调办主任孙国升介绍,目前城区供水超过70%用上南水,直接受益居民达1100万人。   到2020年,北京市将实现密云水库、地下水源与外调水源“三水联调”,南水主要用于城市生活,为中心城和新城20座自来水厂提供水源,供水范围基本覆盖北京平原地区,惠及人口2000万。   天津市水务局副巡视员刘长平说,截至目前,天津新增水量10.6亿立方米,一半以上城市居民吃上南水,从“单一引滦”变为“双水源保障”,相当于增加一条输水生命线,城市供水“依赖性、单一性、脆弱性”矛盾得到有效化解。   用水节约了,节水优先不“任性”   南水来之不易,受水区坚持节水优先,用水不“任性”。   孙国升介绍,北京量水而行,坚持“喝、存、补”原则,调来的15.8亿立方米南水,先满足“喝”,70%供给自来水厂,用于城市生活用水;另外要“存”,目前2亿立方米水存到密云水库、怀柔水库、十三陵水库和大宁调蓄水库,对北京水资源调配起到重要作用;还要“补”,进行地下水回补。   北京严格管水,拧紧“水龙头”,去年全市换装7.8万套高效节水器具。多用再生水,北京七成以上河湖补水来自再生水,去年再生水占到用水总量的1 4,成为稳定的“第二水源”。“十二五”期间,北京年均节水1亿立方米,相当于每年省出一个大型水库。   天津精打细算,把水细分为5种:地表水、地下水、外调水、再生水和淡化海水,实现了差别定价、优水优用,工业用水重复利用率达到92%,再生水利用率达到30%以上。   节水正成为共识。在受水区的一个个节水型小区,淘米水先洗菜、再浇花,洗衣水用来冲厕所,“一水多用”成为许多市民的生活习惯。天津建成节水型企业1056家,节水型小区476个,覆盖率分别达到44.9%和18.2%。北京建成雨洪利用工程1178处,去年城镇雨水综合利用量达1.62亿立方米。   生态受益了,地下水水位逐步回升   有了地表水,严控地下水,生态效益渐显。得益于南水补充,北京压采地下水1.14亿立方米。同时,向密云、怀柔、顺义水源地试验性补水0.84亿立方米,使区域地下水位明显上升,局部最大升幅达8米。监测显示,今年7月底,北京平原地区地下水平均埋深,较去年同期回升62厘米。   补生态欠账,北京利用南水,向城市河湖补水1.74亿立方米,与现有再生水联合调度,使城市水生态环境得到改善,水质接近地表水Ⅲ类。曾经干涸的卢沟晓月湖重现波光粼粼,83岁的居民徐大妈感慨:“真想不到,还能再看到20年前的场景。”   天津重新划定地下水禁采区和限采区,提出到2020年底,全市深层地下水年开采量控制在0.9亿立方米以内。近两年来,共有80余个用水单位完成水源转换,减少地下水许可采水量1010万立方米,回填机井110余眼。   天津市南水北调办综合处处长董树龙说,天津变生态应急补水为常态化补水,累计向景观河道补水5.2亿立方米,为“美丽天津”建设提供了有力支撑。   “随着南水北调供水常态化,地下水压采目标逐步实现,天津地下水位将会逐步回升。”董树龙说。 (责编:杨晓娜、王佩)相关的主题文章:
