style="text-indent:25px">硬水軟化硬水的軟化需使用離子交換法，它的目的是利用陽離子交換樹脂以鈉離子來交換硬水中的鈣與鎂離子，以此來降低水源內(nèi)之鈣鎂離子的濃度。其軟化的反應(yīng)式如下：Ca2++2Na-EX→Ca-EX2+2Na+1Mg2++2Na-EX→Mg-EX2+2Na+1title式中的EX表示離子交換樹脂，這些離子交換樹脂結(jié)合了Ca2+及Mg2+之後，將原本含在其內(nèi)的Na+離子釋放出來。樹脂基質(zhì)（resin matrix）內(nèi)藏氯化鈉，在硬水軟化的過程中，鈉離子會逐漸被使用耗盡，則交換樹脂的軟化效果也會逐漸降低，這時需要作還原（regeneration）的工作，也就是每隔固定時間加入特定濃度的鹽水，一般是10%，其反應(yīng)方式如下：Ca-EX2+2Na+ （濃鹽水）→ 2Na-EX+Ca2+Mg-EX2+2Na+ （濃鹽水）→ 2Na-EX+Mg2+衢州鋼結(jié)構(gòu)可拆裝水處理廠家一級水處理是它通過機(jī)械處理，如格柵、沉淀或氣浮，去除污水中所含的石塊、鐵離子、錳離子、油脂等。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">廢水集水池的作用是匯集、儲存和均衡廢水的水質(zhì)水量。各個車間的生產(chǎn)廢水，其排出的廢水水量和水質(zhì)一般來說是不均衡的，生產(chǎn)時有廢水，不生產(chǎn)時就沒有廢水，甚至在一日之內(nèi)或班產(chǎn)之間都可能有很大的變化，特別是精細(xì)化工行業(yè)的廢水，如果清濁廢水不分流，則工藝濃廢水與輕污染廢水的水質(zhì)水量變化很大，這種變化對廢水處理設(shè)施設(shè)備的正常操作及處理效果是很不利的，甚至是有害的。因此廢水在進(jìn)入主要污水處理系統(tǒng)前，都要設(shè)置一個有一定容積的廢水集水池，將廢水儲存起來并使其均質(zhì)均量，以保證廢水處理設(shè)備和設(shè)施的正常運(yùn)行。</p><p style="text-indent:25px">去離子法去離子法的目的是將溶解於水中的無機(jī)離子排除，與硬水軟化器一樣，也是利用離子交換樹脂的原理。在這使用兩種樹脂-陽離子交換樹脂與陰離子交換樹脂。陽離子交換樹脂利用氫離子（H+）來交換陽離子；而陰離子交換樹脂則利用氫氧根離子（OH-）來交換陰離子，氫離子與氫氧根離子互相結(jié)合成中性水，其反應(yīng)方程式如下：M+x+xH-Re→M-M-Rex+xH+1A-z+zOH-Re→A-Rez+zOH-1上式中的的M+x表陽離子，x表電價數(shù)，M+x陽離子與陽離子樹脂上H-Re的氫離子交換，A-z則表陰離子，z表電價數(shù)，A-z與陰離子交換樹脂結(jié)合後，釋放出OH-離子。H+離子與OH-離子結(jié)合後即成中性的水。這些樹脂之吸附能力耗盡之後也需要再還原，陽離子交換樹脂需要強(qiáng)酸來還原；相反的，陰離子則需要強(qiáng)堿來還原。陽離子交換樹脂對各種陽離子的吸附力有所差異，它們的強(qiáng)弱程度及相對關(guān)系如下：Ba2+>Pb2+>Sr2+>Ca2+>Ni2+>Cd2+>CU2+>Co2+>Zn2+>Mg2+>Ag1+>Cs1+>K1+>NH41+>Na1+>H1+水處理通過物理的、化學(xué)的手段，去除水中一些對生產(chǎn)、生活不需要的物質(zhì)，以達(dá)到國家規(guī)定的水質(zhì)標(biāo)準(zhǔn)的過程。</p><div
