近日，一则“北京最会喝水家庭”的新闻，使北京市自来水成为人们关注的焦点。一对长年从事水质研究的夫妻称，北京市自来水中硝酸盐含量的指标已接近国家标准，且20年不喝自来水。

recently,a"The most will drink family in Beijing"The news,The tap water in Beijing has become the focus of people.A married couple years engaged in the study of water quality,Beijing index of nitrate content in water has been close to the national standard,And 20 years do not drink tap water.

　　“水专家”不喝自来水，这引起了北京市不少市民的担忧。

"Water experts"Do not drink tap water,This caused concern about a Beijing a lot of people.

　　1月7日，北京市自来水集团新闻发言人梁丽称，北京市自来水符合国家106项标准，是安全的水，请市民放心饮用。

出厂水达到国家标准 The factory water reached the national standard

　　当天，北京市自来水集团公布了2012年第四季度的检测数据。数据显示，北京市自来水的浊度、硝酸盐含量、硬度和消毒副产物等106项指标全部达到或优于国家标准。

On the day,Beijing municipal tap water group released in the fourth quarter of 2012 testing data.Data showed that,Beijing municipal tap water turbidity/Nitrate content/Hardness and disinfection by-products such as all 106 indexes reach or exceed national standards.

　　对于此次引发关注的硝酸盐含量，北京市自来水集团水质监测中心主任林爱武说，国家标准规定，地表水的硝酸盐含量要小于10毫克/升，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，都按照10毫克/升来控制。

For this cause the nitrate content of attention,Beijing municipal tap water group love WuShui Lin, director of the center for water quality monitoring,National standard,Surface water nitrate content of less than 10 mg/l,If the use of underground water,Can stretch to 20 mg/l.Beijing 60% are using surface water,Only 40% of the use of underground water,All control according to 10 mg/l.

　　梁丽介绍，自来水集团已建立了从源头到龙头全过程水质监测控制体系。首先在源头处设置了生物监测原水系统，对原水进行预处理。“在用户龙头我们也是按国家标准设置了用户终端采样点。去年是243个监测点。从今年1月1日开始，监测点的数量达到302个。”林爱武说。

LiangLi introduced,Tap water group has established the whole process from the source to the tap water quality monitoring and control system.First in a setting source the raw water biological monitoring system,Pretreatment of raw water."The user tap we also set up a user terminal sample point according to the national standards.Last year was 243 monitoring stations.Start from this year on January 1,,Up to 302 the number of monitoring stations."Lin love WuShui.

　北京自来水为何“硬” Tap water in Beijing"hard"

　　家住北京南城的王女士反映，南城水质普遍不好，烧水觉得水碱重，不好喝。网友甚至调侃说“城墙砖儿，电线杆儿，自来水儿，北京三硬！不硬不要钱！”尽管北京市自来水符合国家标准，“硬”和碱味儿重却让不少市民感到困扰。

ShuiEr,Beijing three hard!No hard don't money!"Despite the Beijing municipal tap water conforms to the national standard,"hard"And alkali flavor son have let many people feel troubled.

　　“北京的地下水是碳酸盐型的，钙、镁的含量比较多，所以它烧开以后大家会感觉到有水碱。”林爱武解释说，水碱由钙镁离子构成，对人体没有害处。

"Beijing groundwater is carbonate type,calcium/The content of magnesium is more,So it bring to a boil after everyone will feel scale."LinAiWu explained,Scale composed of calcium and magnesium ions,There is no harm to human body.

　　硬度国家标准规定是450毫克每升。梁丽介绍，北京自来水集团生产的自来水硬度控制在380毫克/升以下。“为了降低硬度，自来水集团还采取使用地下水与地表水勾兑，以降低硬度。这样可以部分解决一些市民反映的口感问题。”

Hardness national standard is 450 mg per litre.LiangLi introduced,Beijing water group production of tap water hardness control below 380 mg/l."In order to reduce the hardness,Tap water group also take use of groundwater and surface water blending,In order to reduce the hardness.This part can solve the problem of some citizens reflect the taste of."

水质可上网查询 Water quality can surf the Internet inquires

For people concerned about the living environment quality,In the future they can not only inquires into the air quality monitoring data,Tap water quality information will be open to the public.

　　北京市自来水集团宣布，从今年1月15日起，该集团将首次通过门户网站向社会公布供水水质信息。水质信息每季度公布一次，每季度第一个月的15日前，公布上一季度的水质检测结果。每年1月15日之前，还将公布上年度出厂水的全部106项指标的检测结果。公布的范围将涵盖自来水集团市区供水范围内及南口、门头沟、怀柔、密云、延庆、房山、大兴、通州、长辛店9个郊区县的管网水水质和出厂水水质信息。

Beijing municipal tap water group announced,From this year January 15,The group will be announced through the portal for the first time to the water quality information.Water quality information published quarterly,Every quarter for the first months of the 15 th,Announced the first quarter of the water quality test results.Before 15 January each year,Will also be announced last factory water test results of all 106 indicators.Published will cover the scope of the tap water group within the scope of the urban water supply and nankou/vallely/huairou/A cloud/yanqing/Well as the/daxing/tongzhou/Long xin shop 9 JiaoOuXian pipeline network of water quality and effluent water quality information.

　　管网水水质的公布内容包括浑浊度、色度、臭和味、消毒剂余量、菌落总数、总大肠菌群、耗氧量7项指标的最大值、最小值。出厂水质的公布内容为《生活饮用水卫生标准》中42项常规指标每季度检测结果的最大值、最小值。

Network consists of turbidity water quality/chroma/Smell and taste/Disinfectant allowance/Total number of colonies/Total coliform bacteria/The maximum oxygen consumption 7 indexes/The minimum.The factory water quality for the published content[Drinking water hygiene standards]The testing results of conventional index quarterly 42 items in maximum/The minimum.
