  • 自来水污染有多严重!
  • 本站编辑:浙江金鸣环境科技有限公司发布日期:2019-09-21 14:04 浏览次数:

自来水中致癌物质多达25种,另外还有12种结石物质,污染严重的自来水最多的有害物质高达700多种。

尿结石、胆结石这些结石疾病有90%是因为饮用了不健康的自来水造成的,城市的自来水消毒基本采用的都是余氯消毒,虽然在一定程度上对水中的细菌和病毒去除作用,但长期饮用含有余氯的水对人体也有不同程度的危害。

现在仍有很多人认为自来水是最好的水,这其实是不对的,因为自来水它不能对人体起到平衡酸碱度的作用,而且自来水在生产过程中最主要的消毒剂是漂白粉,即氯离子。

更为重要的是因为自来水是经过处理后再通过管道送到我们家中的,所以存在严重的金属管道重金属超标等二次污染,会对人体产生极大的影响。

自来水对人体的危害是很大的,可是人们的生活是离不开水的,比如用它来洗脸、刷牙、做饭、洗衣服等等,是大家在日常生中不可或缺的东西,可是随着很多的重工业、农业、化工产品等对于河流的污染,对于自来水也说也是受到了影响了,所以要喝自来水的时候一定要记住,要喝烧开了的水,不能喝生水,不然那些有害物质会直接进入你的身体的。

自来水中究竟有多少你看不见的有害物质

1、铁锈、铅、砷等重金属污染

自来水厂流出来的自来水在处理不彻底的情况下,通过密密麻麻的市政管道,特别是年代较久的,日积月累管道锈蚀,很容易造成重金属等二次污染,有些铜制龙头由于生产工艺上的局限性,也会产生铅污染。

饮用受到这样污染的水,会使身体的肝脏遭受损害。

2、自来水管渗漏与污染

但在管道输送过程中,由于各分支管道有大量的水泵抽水,常常造成管内负压,地下的污水完全有可能渗入管道,污染到管内自来水。

如果损坏的水管周围有医院、养殖场、垃圾堆、污水池等等,污水渗入管内是不可避免的事。除此之外,部分城市的管网设计不科学,天然气管道、自来水管道、生活污水管道等错综交叉,容易发生泄漏和污染。

3、微生物胶体、细菌等污染

因为有些校区楼层较高,自来水无法达到高层,只得在楼顶建设水箱,再采用增压泵向水箱供水,而很多高层建筑的储水箱长时间未有效清洁也容易滋生细菌、生红虫,尤其在天热、咸潮季节时,问题更严重。

There are as many as 25 carcinogens in the tap water, and another 12 kinds of stone substances.

Urine stone, gallstone these calculous disease have 90% because drank unhealthy tap water to cause, city tap water is disinfected basically those who use is residual chlorine disinfect, although be opposite on certain level the bacterium of water and virus purify action, but long-term drinkable the water that contains residual chlorine also has different level harm to human body.

Many people still think that tap water is the best water, but this is not true, because tap water does not balance the ph of the human body, and the main disinfectant in the production process of tap water is bleach, namely chlorine ion.

What is more important is that tap water is delivered to our homes through pipes after treatment. Therefore, there are serious secondary pollution such as excessive heavy metal in metal pipes, which will have a great impact on human body.

Tap water to human body harm is very big, but the life of people is inseparable from the water, such as to use it to wash my face, brush your teeth, cooking, washing clothes and so on, is everyone indispensable things in daily life, but with a lot of heavy industry, agriculture, chemical products, such as for river pollution, also said to tap water is also affected, so remember to drink tap water, drink boiling water, cannot drink water, or those harmful substances will directly to your body.

How many harmful substances are there in tap water that you can't see

1. Heavy metal pollution such as rust, lead and arsenic

Under the condition that the tap water flowing from the water plant is not completely processed, it will pass through the dense municipal pipelines, especially the old ones, which will be corroded over time. It is easy to cause the secondary pollution of heavy metals, etc. Some copper faucets will also produce lead pollution due to the limitations of the production process.

Drinking such polluted water can damage the body's liver.

2. Water pipe leakage and pollution

But in the pipeline transmission process, because each branch pipe has a large number of pumps pumping water, often cause negative pressure inside the pipe, underground sewage is likely to infiltrate into the pipe, pollution to the tap water inside the pipe.

If there are hospitals, farms, garbage dumps, sewage ponds, etc. around the broken pipes, it is inevitable that sewage will seep into the pipes. In addition, the pipe network design of some cities is not scientific, natural gas pipeline, tap water pipeline, sewage pipe and other complex, easy to leak and pollution.

3, microbial colloid, bacteria and other pollution

Because some campus floor is high, tap water can not reach the high-rise, had to build water tank on the roof, and then use booster pump to water tank, and a lot of high-rise buildings storage tank for a long time not effective clean is easy to breed bacteria, red insects, especially in the hot, salty season, the problem is more serious.
