自來(lai)水常見的異味(wei)原因與處理(li)方法-【眾信管(guan)業】

       現如今人們物質(zhi)文化(hua)生活水(shui)(shui)平(ping)的不斷(duan)提(ti)高的同時(shi)對自(zi)來水(shui)(shui)水(shui)(shui)質(zhi)的要求也越(yue)來越(yue)高，水(shui)(shui)質(zhi)稍有(you)變化(hua)就會向相(xiang)關部門進行投訴。用(yong)戶的水(shui)(shui)質(zhi)投訴中哪些確(que)實是水(shui)(shui)質(zhi)出現了問(wen)題(ti)，又有(you)哪些是正常現象呢(ni)？采用(yong)又能解決(jue)哪些問(wen)題(ti)呢(ni)？ 

       自來水中有藥味 

       家中(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)自(zi)(zi)(zi)來(lai)水(shui)中(zhong)(zhong)(zhong)(zhong)有一股刺鼻的(de)(de)(de)藥味，但燒成(cheng)開水(shui)后就消(xiao)(xiao)失了(le)。 用戶反映的(de)(de)(de)自(zi)(zi)(zi)來(lai)有藥味，其實(shi)不是(shi)藥味，一般是(shi)自(zi)(zi)(zi)來(lai)水(shui)中(zhong)(zhong)(zhong)(zhong)氯(lv)(lv)的(de)(de)(de)味道。實(shi)際(ji)上加氯(lv)(lv)是(shi)自(zi)(zi)(zi)來(lai)水(shui)保持衛生(sheng)所必 需(xu)(xu)的(de)(de)(de)，在(zai)自(zi)(zi)(zi)來(lai)水(shui)處理過程中(zhong)(zhong)(zhong)(zhong)，必 需(xu)(xu)進行加氯(lv)(lv)消(xiao)(xiao)毒來(lai)保證消(xiao)(xiao)毒的(de)(de)(de)效(xiao)果(guo)(guo)。一定量(liang)的(de)(de)(de)余氯(lv)(lv)存在(zai)管(guan)道中(zhong)(zhong)(zhong)(zhong)是(shi)用來(lai)防止(zhi)管(guan)道二次(ci)污染。對(dui)水(shui)中(zhong)(zhong)(zhong)(zhong)余氯(lv)(lv)的(de)(de)(de)存在(zai)是(shi)允許的(de)(de)(de)但不得超過0.4mg/L。如果(guo)(guo)家中(zhong)(zhong)(zhong)(zhong)自(zi)(zi)(zi)來(lai)水(shui)中(zhong)(zhong)(zhong)(zhong)氯(lv)(lv)味較大則可能是(shi)余氯(lv)(lv)超標,需(xu)(xu)要(yao)向供水(shui)部門反映進行檢測。自(zi)(zi)(zi)來(lai)水(shui)中(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)余氯(lv)(lv)添(tian)加是(shi)為了(le)防止(zhi)二次(ci)污染,如果(guo)(guo)二次(ci)污染能解決則不需(xu)(xu)要(yao)余氯(lv)(lv)存在(zai)，增強不銹鋼管(guan)就是(shi)可以(yi)有效(xiao)防止(zhi)二次(ci)污染的(de)(de)(de)自(zi)(zi)(zi)來(lai)水(shui)管(guan)道。

       自來水(shui)中的(de)腥、臭味

       自(zi)來水(shui)中(zhong)的臭味主要(yao)是(shi)由管(guan)(guan)道(dao)中(zhong)陳(chen)水(shui)引(yin)起的，即(ji)自(zi)來水(shui)在管(guan)(guan)道(dao)中(zhong)留(liu)存時間過(guo)長，以(yi)(yi)至(zhi)于微生(sheng)物(wu)滋生(sheng)而產生(sheng)臭味。腥(xing)味的主要(yao)來源是(shi)藻(zao)類繁(fan)殖，水(shui)中(zhong)存在鐵、泥等物(wu)質時，水(shui)中(zhong)也會出現腥(xing)味。針對水(shui)中(zhong)的腥(xing)、臭味，需要(yao)定期將管(guan)(guan)道(dao)末端中(zhong)的陳(chen)水(shui)排盡(jin)，即(ji)管(guan)(guan)道(dao)清洗(xi)。對于藻(zao)類一旦生(sheng)成，目(mu)前的傳統凈水(shui)工藝是(shi)很(hen)難徹(che) 底(di)解決的，除非使用深(shen)度處(chu)理(li)工藝。在沒有深(shen)度處(chu)理(li)工藝的水(shui)廠，唯 一的辦法進行(xing)管(guan)(guan)網改造，采用不(bu)生(sheng)銹不(bu)結污垢不(bu)滋生(sheng)微生(sheng)物(wu)的增(zeng)強(qiang)不(bu)銹鋼管(guan)(guan)作為(wei)輸水(shui)管(guan)(guan)道(dao)。增(zeng)強(qiang)不(bu)銹鋼管(guan)(guan)表(biao)面光滑不(bu)生(sheng)銹不(bu)結污垢所以(yi)(yi)微生(sheng)物(wu)無法駐足滋生(sheng)，是(shi)目(mu)前最(zui) 為(wei)理(li)想的供水(shui)管(guan)(guan)材。

       自來水(shui)中的其(qi)他(ta)異味(wei) 

       自來水(shui)(shui)(shui)(shui)(shui)(shui)中有(you)油(you)漆味(wei)、汽油(you)味(wei)、塑料味(wei)等(deng)化學類(lei)(lei)的(de)異味(wei)的(de)話。一(yi)是(shi)自來水(shui)(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)(shui)源(yuan)受(shou)到污(wu)染，水(shui)(shui)(shui)(shui)(shui)(shui)源(yuan)中的(de)水(shui)(shui)(shui)(shui)(shui)(shui)溶解了(le)有(you)機(ji)污(wu)染物諸如苯酚類(lei)(lei)化合物、油(you)類(lei)(lei)等(deng)無法被(bei)的(de)凈水(shui)(shui)(shui)(shui)(shui)(shui)工(gong)藝去除。二(er)是(shi)供水(shui)(shui)(shui)(shui)(shui)(shui)設施(shi)(shi)管道(dao)等(deng)維(wei)修(xiu)(xiu)造成的(de)。這種情況要(yao)立即向(xiang)自來水(shui)(shui)(shui)(shui)(shui)(shui)公司反(fan)應以(yi)便查明原因盡快(kuai)回復正常供水(shui)(shui)(shui)(shui)(shui)(shui)。水(shui)(shui)(shui)(shui)(shui)(shui)源(yuan)受(shou)到污(wu)染，一(yi)般(ban)在取(qu)水(shui)(shui)(shui)(shui)(shui)(shui)口投加粉末(mo)活性炭，吸附原水(shui)(shui)(shui)(shui)(shui)(shui)中的(de)污(wu)染物。但(dan)是(shi)從(cong)長遠(yuan)目(mu)光來看必(bi) 須要(yao)加強水(shui)(shui)(shui)(shui)(shui)(shui)源(yuan)地保(bao)護。如果是(shi)供水(shui)(shui)(shui)(shui)(shui)(shui)設施(shi)(shi)的(de)維(wei)修(xiu)(xiu)造成的(de)則需要(yao)對維(wei)修(xiu)(xiu)設備進(jin)行(xing)沖洗干(gan)凈后恢復供水(shui)(shui)(shui)(shui)(shui)(shui)。可(ke)以(yi)有(you)效(xiao)降低漏損減(jian)少使用(yong)過程中的(de)維(wei)修(xiu)(xiu)，服(fu)役中幾乎零維(wei)護。

       用(yong)戶對水質問題(ti)的投訴多而雜，凡是用(yong)戶提出(chu)問題(ti)，都(dou)是用(yong)戶認(ren)為自(zi)(zi)來水可(ke)能出(chu)現問題(ti)了，擔(dan)心(xin)是飲用(yong)的危害，自(zi)(zi)來水公(gong)司(si)需認(ren)真對待。
