Why is My Water Brown? Your water may be brown because of sediment, minerals or rust that have built up in the water mains over time. These sediments can break loose and enter your home’s water supply, causing the water to appear brown or discolored. By far the most common cause of brown water coming out of residential plumbing systems is a recent pipe replacement in the home or from broken water pipes. When rust slips off the pipes and into your water supply, your water turns brown. During repairs, there’s a change in water pressure which often dislodges loose deposits from the piping.

"We saw almost a near record use of open hydrants and water flow. Probably the highest use that we've seen in at least a decade, if not more. It can cause brown water issues if you disturb some of the sediments because you're not using the right tools and opening it correctly. So that's another thing that we're concerned about.

你自己看看那谣言,有点常识也知道不对啊
这位是有病吧?臭就是粪水吗
主要是没基本常识的人太多,他这个谣言,别说当地人,这版上也一大堆人相信。。
挺好, 造谣传谣杀人于无形, 改用重典
夏天有时候就这样。老家的海水浴场,我去年回去看到每天用推土机在沙滩上清理那些绿藻
不仅仅是不同的系统,不可能相联
而且下水系统没啥压力,而自来水管是有很大水压的。。 所以哪怕两个系统真的联起来,也必然是自来水管的干净水,被水压压到下水系统里,而不可能反过来。。
赤裸裸地造谣太狠了,上水管道和下水管道 人为接在一起 这种瞎编都能张口说。自己都跑了,也算做好心理准备了!
疑似粪水这种还能说得过去,本来就像粪水的颜色,疑似也没啥大问题。
对啊,所以说没常识,下水管道加这么大压力,马桶搞不好成了喷泉。
本版有些人根本不在乎啥真相,只要能喷国内就好
绿藻归绿藻,这种似粪水,不是绿藻能解释的,自来水厂水源被严重污染了,管理确实有严重问题,也确实要彻底调查!
对,是屎一样的巧克力,绝对不能说是巧克力一样的屎
尼玛你说是下水道反渗到上水管里也行啊,接驳13处粪水排污管是电诈集团专门测试筛选弱智的吗?高压的上水管接低压排污管还能让粪水进入上水管,这个技术难度有点高
大概率就是因为某些原因,水管内部水压变化,导致水管里多年的build up被冲下来了。。

水源就算是接的粪水也好藻类污染的水也好,筛子的过滤和初步的coagulation混凝、絮化和沉淀过程一定会有,大大小小的固体物质会被从水里消除掉。
再说了,水质有异味有颜色成了那样,这符合哪门子的水处理质检,是怎么进入供水管网的?
对了,想起甘肃的铅污食品,其实自来水对于防止铅污染也是考虑,如果知道本地有铅污染危险,水厂就会调节自来水酸碱度,不让铅污染物溶解在自来水里。

冲出来的大多是水管里的水垢,自然会有固体物质。。
整体顺序差不多是:水源污染=》水臭=》换水源=》水管压力变化 =》水管里的水垢被大量冲出。。。
所以水臭和水中的异物,其实是两个不同的来源。。 前者来自于水源地,后者是水管内部多年build up
真有问题的人不该解决吗?川大总统也忙着解决有问题的人呢,不少啊 :)
让他活在这个世上 是天朝最大的恩惠... 你看看多少海外那些混的穷酸样的人 在他所在地压抑老实的像个猫! 只有黑中国的时候像打了鸡血 这样的人我见多了
我学医的 现在也教微生物学 从来没有听说过有这样的algae “ 藻类厌氧降解产生的硫醚类物质” 难道发现了新的微生物 全世界其他国家都不知道?
不是糞水
應該是
糞 風味 水
應該是 硫醇 不是 硫醚
我以前實驗做過 12 14 16 硫醇 那個鮮香啊...
硫醇類化合物,尤其是低級硫醇,常被形容為有糞便或腐爛的氣味,這與它們在自然界中的來源和代謝途徑有關。 許多硫醇類化合物,如甲硫醇和丁硫醇,都是由生物分解產生的,並且在動物的排泄物,如糞便,中含量較高。
硫醚通常具有不愉快的氣味,特別是揮發性的硫醚,其氣味多被描述為腐爛、臭味或類似於腐爛的蔬菜、臭雞蛋的味道。
只能说,中国造谣的人多得很。
不是第一次了, 前后杭州出水事故已经三次了
说粪水是不是造谣,和本楼说的事好像没半点关系吧?
本楼的事很简单 - 那个“警情通告”是不是邵某编的?
居民一开始抱怨的明明是水有臭味 有人造谣是粪水进了水管,所以是粪臭,
然后你用微生物不会有粪臭去论证 你这老师的逻辑思维能力不太好呀
