中新网北京1月7日电 (记者 尹力)日前，一则“北京一对夫妇已20年不喝自来水”的新闻引发了网友热议，不少北京民众因此“谈水色变”。北京市自来水集团发言人梁丽7日表示，该集团供应的自来水是安全的水，民众可放心饮用。

Beijing Beijing, jan. 7, (The reporter YinLi)Prior to the,a"Beijing a couple already 20 years do not drink tap water"The news caused a netizen hot debate,So many Beijing residents"Talk about color change".Beijing municipal tap water group spokesman said LiangLi 7,The supply of tap water is safe water,People can rest assured to drink.

　　日前有媒体报道，北京一对夫妇常年与饮用水打交道。丈夫在国家发改委公众营养与发展中心饮用水产业委员会工作，妻子则是北京保护健康协会健康饮用水专业委员会负责人。由于担心北京自来水水质逐渐变差，他们已经20年不喝自来水，只喝矿泉水，更自诩为“北京市最会喝水的家庭”。

Recently there are media reports,Beijing a couple year deal with drinking water.Her husband in the national development and reform commission public nutrition and development center drinking water industry committee work,Wife is Beijing health protection association of professional committee of the healthy drinking water.For fear of tap water in Beijing gradually deteriorated water quality,They have 20 years do not drink tap water,Only drink mineral water,More so-called"Beijing's drinking water will family".

　　针对民众对目前北京供水水质状况的关心，梁丽明确表示，北京的饮用水及水源地是中国内地最好的水，集团供水均符合国家106项标准。

In view of the public concern for the current water quality in Beijing,LiangLi made it clear that,Beijing's drinking water and water is the best water in mainland China,Group of water supply are in line with national standards for 106.

　　在北京城区，每天有200多万立方米自来水，通过8800公里的管线送到居民家中。如果采用地下水作为原水，那么生产自来水简单又安全。问题是北京从2000年以来连续12年干旱，水资源极度紧张，不得不以地表水作为主要原水。目前，市自来水集团使用的密云水库等本地水水源和河北水库水多达22处，2014年还将采用上千公里外的丹江口水源。这在全国乃至全世界都十分罕见，这对自来水集团供水调度、水处理工艺、水质监测等工作提出了更高的挑战。

In Beijing city,There are more than 200 cubic meters of water a day,Through a 8800 km pipeline to the inhabitants of home.If the groundwater as a raw water,So water is simple and safe production.The problem is Beijing for 12 years drought since 2000,Water extremely nervous,Have to surface water as the main raw water.At present,,Municipal tap water group use the miyun reservoir local water, such as water and hebei reservoir water up to 22,2014 will also be the danjiangkou water for thousands of kilometers away.This in the country and the world is very rare,The tap water supply scheduling group/Water treatment process/Water quality monitoring work put forward higher challenge.

　　梁丽谈到，为保证北京的供水安全，自来水集团建立了全过程的水质监控体系，对水源水、出厂水、管网水、用户终端水进行全过程的水质监控，保证自来水水质达到国家标准。如利用在线监测仪、定期取样化验等方式，对水源的水质进行监控；通过水厂运转班组、水厂化验室、水质监测中心三级水质检测，确保出厂水符合106项国家饮用水卫生标准；在供水管网和用户终端建立了243个水质监测点，对管网水、用户龙头水进行全过程的质量监控。

LiangLi talked about,In order to ensure the safety of the water supply in Beijing,Tap water group set up the whole process of water quality monitoring system,To the water/The factory water/Pipeline network of water/The user terminal water for the whole process of water quality monitoring,Ensure water water quality reached the national standard.Such as using online monitoring instrument/Regular sampling test, etc,For monitoring the water quality of water;Through the waterworks operation team/Water laboratory/Water quality monitoring center 3 water quality inspection,Ensure that water conforms to the 106 national sanitary standard for drinking water;Established in water supply network and user terminals 243 water quality monitoring stations,The pipeline network of water/The user tap water for the whole process of quality control.

　　相关报道提出，随着北京地下水位的下降，地下水的“硬度”明显增加。北京自来水集团水质监测中心主任林爱武解释称，所谓“硬度”，就是水中的碳酸钙含量，烧开会形成水碱。国家标准规定自来水硬度不超过450毫克/升，而北京自来水集团采取使用地下水与地表水勾兑，以降低硬度，将其控制在380毫克/升以下，在此范围内的硬度对民众健康有益而无害。

Related reports,As the underground water level drop in Beijing,Of groundwater"hardness"A significant increase in.Beijing water group director of the center for water quality monitoring LinAiWu explanation says,The so-called"hardness",Is the water content of calcium carbonate,And the formation of scale of the meeting.National standard of tap water hardness is not more than 450 mg/l,And tap water in Beijing group take the use of groundwater and surface water blending,In order to reduce the hardness,The control below 380 mg/l,In the range of hardness on people's health and harmless.

　　据林爱武介绍，根据去年四季度的检测，北京地下水的硝酸盐最高只有9.7毫克/升。国家标准地表水小于10毫克/升，但如果使用地下水源，可以放宽到20毫克/升。北京60%都是使用地表水源，只有40%使用地下水源。但即便国家标准放宽到20毫克/升，北京也是按10毫克/升控制。

Introduce according to LinAiWu,According to the fourth quarter of last year,Beijing top of nitrate in groundwater is only 9.7 mg/l.National standard of surface water less than 10 mg/l,But if you use the underground water,Can stretch to 20 mg/l.Beijing 60% are using surface water,Only 40% of the use of underground water.But even the national standard to 20 mg/l,Beijing is also controlled by 10 mg/l.

　　林爱武谈到，自2007年新饮用水国家标准实施后，自来水集团对于消毒副产物要求更严格，多年来采取先进的处理工艺，使消毒副产物得到控制。以其中一项三氯甲烷为例，1997年第九水厂该项平均值为0.019毫克/升，国标为0.060毫克/升。2012年该项平均值为0.011毫克/升，通过数字可以表明，这么多年虽然在水源多样化、水质复杂化的情况下，通过处理工艺，该项指标得到了很好控制。

LinAiWu talked about,Since 2007, after the implementation of the new national standard of drinking water,Tap water group for more strict disinfection by-products,Adopt the advanced treatment technology for many years,The disinfection by-products under control.In the case of one of chloroform,9 waterworks in 1997 the average was 0.019 mg/l,Gb is 0.060 mg/l.In 2012, the average is 0.011 mg/l,Through the digital can show,So many years even though in water resources diversification/Under the condition of complicated water quality,Through the process,The index has been very good control.

　　北京市水务局曾于2012年12月27日发布信息称，2013年1月15日开始，北京公共供水企业将通过网络等渠道公布其供水水质信息，主要包括管网水水质和出厂水水质两大组成部分。其中，出厂水水质每季度将公布42项常规指标。每年1月15日前，将公布上年度出厂水的全部106项指标的检测结果。届时，民众可通过相关网站查询有关供水水质信息。(完)
