桶装水还能喝吗?看看放几天就长绿藻!!
据了解,人的一生要喝60吨的水,可饮水的健康却不是一件小事。近日,杭州市民张女士向笔者反映,办公室开封了一桶某品牌的矿泉水,过了三四天,发现剩下的桶装水内已长了很多青苔。一位同事饮用的杯子剩下一些水,第二天上班时,看到杯子里也长了“绿毛”。甚至有同事喝了这桶水后拉肚子。
It is understood that a person's life should drink 60 tons of water, but the health of drinking water is not a small matter. Recently, the Hangzhou citizen Zhang told me that the office opened a bucket of mineral water of a brand. After three or four days, it found that many of the remaining bottled water had grown many moss. A colleague drinking a cup of water left, second days to work, see the cup is also long "green hair." Even a colleague drank the bucket of water and pulled his stomach.
桶装水长绿藻水质存放不当等为诱因
The reason for the improper storage of the water quality of the barreled green algae
张女士遇到的情况很多人也遇到过,据知情人士介绍,住在杭州市富阳市凤浦路的汪大姐也遭遇了桶装水“长绿藻”的情况。汪大姐说:“夏天,家里的矿泉水放上几天就会长出绿藻,现在我家连矿泉水都是烧开后再喝的。”汪大姐一开始以为是牌子问题,但是一连换了几家桶装水牌子都会出现这样的情况,汪大姐都对水的质量产生了怀疑。
Many people have met with Ms. Zhang. According to people familiar with the matter, Wang Dali, who lives in Fengpu Road, Fuyang, Hangzhou, has also encountered the situation of "long green algae" in barreled water. "In summer, the mineral water in the family will grow out of green algae in a few days, and now my mine is even a drink after the burning of the mineral water." Wang Da Jie initially thought it was a brand problem, but there were several barrelled water brands that would happen in a row. Wang sister had doubts about the quality of the water.
某品牌桶装水供应商王先生表示,“出现这个情况是正常的,因为矿泉水里面有很多天然的矿物质,一经阳光照晒,就可能长出绿藻”。王先生还介绍,还有可能是因为饮水机长久没清洗,里面的细菌污染了水桶,所以才长了绿藻。
A brand bottled water supplier, Mr. Wang said, "this is normal, because mineral water contains many natural minerals. Once it is exposed to sunlight, it will grow green algae." Mr. Wang also said that it may be because the water dispenser has not been cleaned for a long time, and the bacteria in it pollute the bucket, so the green algae have been grown.
笔者从杭州市区食品检测中心沈莉副主任了解到,出现绿藻可能是由以下几方面原因:1、由于气温的升高,同时空气比较潮湿,我们居住环境的空气中有微量的藻类孢子。一旦这些孢子随空气进入开封后的桶内,只要有阳光的照射就会发生光合作用,生成藻类。藻类在阳光的照射下迅速繁殖,桶内就出现了绿藻。此外,长时间没有饮用完的话也可能会导致菌落超标,助长出现长绿藻的现象;2、矿泉水本身含有一部分的藻类孢子,矿泉水生产设备能过滤一定粒径以上的藻类物质,低于设备过滤粒径以下的少量藻类将无法过滤。由于矿泉水所含矿物质和营养成分比较充足,在阳光直射下也会产生光合作用,时间过长就出现长绿藻的现象;3、生产过程中矿泉水桶的清洗不彻底、消费者使用的饮水机质量不好以及清洗周期过长或清洗不彻底,这些也都是长出绿藻的因素。
The author learned from Shen Li, deputy director of food inspection center of Hangzhou urban area that the emergence of green algae may be caused by the following reasons: 1. Due to the increase of air temperature and the humid air, there are microalgae spores in the air of our living environment. Once the spores come into the open barrel with the air, as long as there is sunlight, photosynthesis will occur and algae are generated. Algae grow rapidly under the sunlight, and green algae appear in the bucket. In addition, long time without drinking enough may also lead to encourage long green algae colony exceed the standard, the phenomenon; 2, mineral water containing algae spores itself part of the mineral water production equipment can filter certain particle size above the algae, lower than the particle size below a small amount of filtering equipment will not be able to filter algae. The mineral water contains minerals and nutrients are abundant, in direct sunlight will produce photosynthesis, long time is long green phenomenon; 3, in the production process of cleaning barrel of mineral water is not complete, the quality of drinking water machine for consumer use is not good and the cleaning cycle is too long or not thorough cleaning, these are also long green factor.
水长时间储存容易二次污染
Long time storage of water is easy to pollute two times
据了解,有一部分家庭遭遇了桶装水长绿藻的事后,家里已经安装了净水器,觉得净水器净化的水比饮水机的水安全。
It is understood that some families suffered from barreled water and long green algae. The water purifier was installed at home, and the water purified by the water purifier was safer than the water of the water dispenser.
笔者据相关部门了解,现阶段没有净水器国家标准,当前国内绝大部分净水器企业是采用外购配件进行改装生产的中小企业,机械化程度低、手工作坊式的多,产品质量参差不齐。所以购买净水器时请选择有信赖保证的品牌。
According to the relevant departments, I don't know that there are no national standards for water purifier at present. Most of the domestic water purifier enterprises are small and medium-sized enterprises which are refitted and manufactured by outsourced parts. The degree of mechanization is low, manual workshops are numerous, and the quality of products is uneven. So when you buy a water purifier, please choose a brand with a trust guarantee.
