一． 設(she)備簡介
     中水(shui)(shui)(shui)(shui)回用(yong)，就是(shi)把(ba)生(sheng)活(huo)污(wu)水(shui)(shui)(shui)(shui)(或城市污(wu)水(shui)(shui)(shui)(shui))或工(gong)業廢水(shui)(shui)(shui)(shui)經過深度技術(shu)處(chu)理，去除各種雜質，去除污(wu)染水(shui)(shui)(shui)(shui)體的有(you)毒、有(you)害物質及(ji)某些(xie)重金屬離子(zi)，進而(er)消毒滅菌，其水(shui)(shui)(shui)(shui)體無(wu)色、無(wu)味(wei)、水(shui)(shui)(shui)(shui)質清澈透明，且達(da)到或好(hao)于國家規(gui)定的雜用(yong)水(shui)(shui)(shui)(shui)標(biao)準(或相關規(gui)定)，廣泛(fan)應用(yong)于企業生(sheng)產或居民生(sheng)活(huo)。
中(zhong)水(shui)(shui)(shui)(shui)(shui)處(chu)(chu)理回用(yong)(yong)(yong)是節水(shui)(shui)(shui)(shui)(shui)和(he)治污(wu)的有(you)效雙贏辦法。應用(yong)(yong)(yong)在生活小區(qu)、建筑小區(qu)、賓館、療養院、綜合樓等生活污(wu)水(shui)(shui)(shui)(shui)(shui)及(ji)部分工業污(wu)水(shui)(shui)(shui)(shui)(shui)。處(chu)(chu)理后，中(zhong)水(shui)(shui)(shui)(shui)(shui)可(ke)用(yong)(yong)(yong)于沖刷廁所、汽車、路途綠化、澆灌綠地(di)及(ji)補償鍋爐(lu)用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)。中(zhong)水(shui)(shui)(shui)(shui)(shui)主(zhu)要指城市(shi)污(wu)水(shui)(shui)(shui)(shui)(shui)或生活污(wu)水(shui)(shui)(shui)(shui)(shui)處(chu)(chu)理后達到一(yi)定(ding)的水(shui)(shui)(shui)(shui)(shui)質(zhi)(zhi)標準，可(ke)在一(yi)定(ding)范圍(wei)內(nei)重復使用(yong)(yong)(yong)的非飲用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)(shui)，其水(shui)(shui)(shui)(shui)(shui)質(zhi)(zhi)介于上水(shui)(shui)(shui)(shui)(shui)與下水(shui)(shui)(shui)(shui)(shui)之間，中(zhong)水(shui)(shui)(shui)(shui)(shui)回用(yong)(yong)(yong)則是將(jiang)城市(shi)污(wu)水(shui)(shui)(shui)(shui)(shui)進(jin)行(xing)處(chu)(chu)理后作為再生資源回用(yong)(yong)(yong)。城市(shi)污(wu)水(shui)(shui)(shui)(shui)(shui)由于水(shui)(shui)(shui)(shui)(shui)量(liang)穩(wen)定(ding)，基(ji)建投(tou)資經(jing)濟，許多國家都將(jiang)中(zhong)水(shui)(shui)(shui)(shui)(shui)回用(yong)(yong)(yong)作為解決(jue)缺水(shui)(shui)(shui)(shui)(shui)問題(ti)的優選方案。因(yin)此，開(kai)展(zhan)中(zhong)水(shui)(shui)(shui)(shui)(shui)回用(yong)(yong)(yong)工作，顯示出了開(kai)源和(he)減少污(wu)染的雙重功(gong)效。

二． 處(chu)理方式 
1、按用途分(fen)類
中水因用途不同有三種處理(li)方式
（1）. 一種(zhong)是將其(qi)處理到飲用水的標(biao)準(zhun)而(er)直接(jie)回用到日常生活中，即實現水資(zi)源(yuan)直接(jie)循環利用，這(zhe)種(zhong)處理方式適用于水資(zi)源(yuan)極(ji)度缺(que)乏的地區(qu)，但投資(zi)高，工藝(yi)復雜；
（2）. 另一種(zhong)是將其處(chu)理(li)到非飲用(yong)(yong)水的(de)標準，主要用(yong)(yong)于不與人體(ti)直(zhi)接接觸的(de)用(yong)(yong)水，如便器(qi)的(de)沖洗，地面、汽車清洗，綠化澆灑，消防(fang)，工業(ye)普通用(yong)(yong)水等(deng)，這(zhe)是通常的(de)中水處(chu)理(li)方式。
（3）.工(gong)業(ye)上可(ke)以利用(yong)中水(shui)(shui)回用(yong)技術將達到外(wai)排標(biao)準的工(gong)業(ye)污水(shui)(shui)進行再(zai)處(chu)理，一(yi)般會加上軟(ruan)化(hua)器，RO，EDI/混床等設備使(shi)其達到軟(ruan)化(hua)水(shui)(shui)，純(chun)化(hua)水(shui)(shui)，超純(chun)水(shui)(shui)水(shui)(shui)平，可(ke)以進行工(gong)業(ye)循(xun)環再(zai)利用(yong)，達到節(jie)約資本，保護(hu)環境的目的。
2、按(an)處理方法分類
按處理方法(fa)，中水處理工藝一般分為 3 種類型：
（1） 物理(li)處(chu)理(li)法(fa)：
膜濾(lv)法(fa)，適用(yong)于水質變化(hua)大的情況(kuang)。
采用這種流程的特點(dian)是：裝置緊湊，容易操作，以(yi)及受負荷變動的影響小。
膜(mo)(mo)濾(lv)(lv)(lv)法是在外(wai)力的作用下，被分離(li)(li)的溶(rong)液以(yi)一定(ding)的流速沿著濾(lv)(lv)(lv)膜(mo)(mo)表面流動，溶(rong)液中(zhong)溶(rong)劑和(he)低分子量物(wu)(wu)質(zhi)、無機離(li)(li)子從高壓側透過濾(lv)(lv)(lv)膜(mo)(mo)進入(ru)低壓側，并作為濾(lv)(lv)(lv)液而(er)排出；而(er)溶(rong)液中(zhong)高分子物(wu)(wu)質(zhi)、膠體微粒及微生物(wu)(wu)等被超(chao)濾(lv)(lv)(lv)膜(mo)(mo)截(jie)留，溶(rong)液被濃縮并以(yi)濃縮形(xing)式排出。
蒸(zheng)發(fa)熱法：適用于任何水(shui)質。
采用這種(zhong)流(liu)程的特點(dian)是：穩(wen)定性高，易于(yu)維護，使用壽命長，操作簡單，不因水質波動而影響設備運行。
蒸(zheng)發熱法是通過(guo)(guo)加(jia)熱蒸(zheng)發，使溶液在蒸(zheng)發體(ti)內(nei)達(da)(da)到(dao)沸點情(qing)況下(xia)分(fen)離出純水(shui)和(he)鹽類(lei)固體(ti)，純水(shui)通過(guo)(guo)蒸(zheng)汽形態(tai)冷凝為純水(shui)，濃縮液經過(guo)(guo)不斷(duan)循環(huan)蒸(zheng)發形成鹽類(lei)固體(ti)。純水(shui)水(shui)質通過(guo)(guo)一(yi)系列過(guo)(guo)濾等措(cuo)施可以達(da)(da)到(dao)中水(shui)回用。
（2）物理化學法：
適用于污水水質變化較(jiao)大的情(qing)況(kuang)。一般采用的方(fang)法有：砂濾(lv)、活性(xing)炭吸附、浮(fu)選(xuan)、混凝(ning)沉淀等。這種流(liu)程(cheng)的特點是：采用中空纖維超濾(lv)器進行(xing)處理，技(ji)術先進，結(jie)構緊湊，占(zhan)地少，系統間歇運行(xing)，管理簡(jian)單。
（3）生物處理(li)法
適用(yong)于有(you)機物含量(liang)較(jiao)高(gao)的污水。一般采用(yong)活性污泥(ni)法(fa)、接(jie)觸(chu)氧化法(fa)（如圖所(suo)示）、生(sheng)物轉(zhuan)盤等生(sheng)物處(chu)理方(fang)法(fa)。或是(shi)單獨使(shi)用(yong)，或是(shi)幾種生(sheng)物處(chu)理方(fang)法(fa)組合(he)使(shi)用(yong)，如接(jie)觸(chu)氧化 + 生(sheng)物濾池(chi)(chi)；生(sheng)物濾池(chi)(chi) + 活性炭吸附(fu)；轉(zhuan)盤十砂(sha)濾等流(liu)程(cheng)。這(zhe)種流(liu)程(cheng)具有(you)適應水力負荷變動能力強(qiang)、產生(sheng)污泥(ni)量(liang)少、維護管理容易等優點(dian)。
當前，由于一(yi)些(xie)國家和地(di)(di)(di)區(qu)在(zai)過度地(di)(di)(di)、毫無(wu)節制地(di)(di)(di)開(kai)發(fa)水(shui)(shui)(shui)(shui)(shui)(shui)資(zi)源的(de)(de)同時，環境保護意識比較(jiao)差，使地(di)(di)(di)表水(shui)(shui)(shui)(shui)(shui)(shui)和地(di)(di)(di)下(xia)水(shui)(shui)(shui)(shui)(shui)(shui)均受到(dao)了(le)不同程度的(de)(de)污(wu)染，使原本具有良好水(shui)(shui)(shui)(shui)(shui)(shui)質(zhi)(zhi)(zhi)的(de)(de)新鮮水(shui)(shui)(shui)(shui)(shui)(shui)供(gong)應受到(dao)限(xian)制；其次，待開(kai)發(fa)的(de)(de)新鮮水(shui)(shui)(shui)(shui)(shui)(shui)源離(li)(li)集中(zhong)(zhong)供(gong)水(shui)(shui)(shui)(shui)(shui)(shui)點(dian)距離(li)(li)較(jiao)遠，一(yi)次性投(tou)資(zi)費用高昂，這樣一(yi)些(xie)缺水(shui)(shui)(shui)(shui)(shui)(shui)地(di)(di)(di)區(qu)無(wu)力擴(kuo)大(da)供(gong)水(shui)(shui)(shui)(shui)(shui)(shui)能力。理到(dao)非飲用的(de)(de)程度，在(zai)此引出了(le)中(zhong)(zhong)水(shui)(shui)(shui)(shui)(shui)(shui)概念。中(zhong)(zhong)水(shui)(shui)(shui)(shui)(shui)(shui)也就是將人(ren)們(men)在(zai)生(sheng)(sheng)活和生(sheng)(sheng)產中(zhong)(zhong)用過的(de)(de)優(you)質(zhi)(zhi)(zhi)雜排(pai)(pai)水(shui)(shui)(shui)(shui)(shui)(shui)(不含糞便和廚(chu)房排(pai)(pai)水(shui)(shui)(shui)(shui)(shui)(shui))、雜排(pai)(pai)水(shui)(shui)(shui)(shui)(shui)(shui)(不含糞便污(wu)水(shui)(shui)(shui)(shui)(shui)(shui))以及生(sheng)(sheng)活污(wu)(廢)水(shui)(shui)(shui)(shui)(shui)(shui)經集流(liu)再生(sheng)(sheng)處理后回(hui)用，充(chong)當地(di)(di)(di)面清潔(jie)、澆花、洗車(che)、空調(diao)冷卻、沖洗便器、消防等不與人(ren)體直接接觸的(de)(de)雜用水(shui)(shui)(shui)(shui)(shui)(shui)。因其水(shui)(shui)(shui)(shui)(shui)(shui)質(zhi)(zhi)(zhi)指標(biao)(biao)低于城市(shi)給水(shui)(shui)(shui)(shui)(shui)(shui)中(zhong)(zhong)飲用水(shui)(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)(shui)質(zhi)(zhi)(zhi)標(biao)(biao)準(zhun)(zhun)，但又高于污(wu)水(shui)(shui)(shui)(shui)(shui)(shui)允(yun)許排(pai)(pai)入(ru)地(di)(di)(di)面水(shui)(shui)(shui)(shui)(shui)(shui)體排(pai)(pai)放(fang)標(biao)(biao)準(zhun)(zhun)，亦即其水(shui)(shui)(shui)(shui)(shui)(shui)質(zhi)(zhi)(zhi)居(ju)于生(sheng)(sheng)活飲用水(shui)(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)(shui)質(zhi)(zhi)(zhi)和允(yun)許排(pai)(pai)放(fang)污(wu)水(shui)(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)(shui)質(zhi)(zhi)(zhi)標(biao)(biao)準(zhun)(zhun)之間，故取名為“中(zhong)(zhong)水(shui)(shui)(shui)(shui)(shui)(shui)”。
中水(shui)(shui)開發與(yu)回(hui)用(yong)(yong)(yong)技(ji)術得(de)到了(le)迅速發展，在美國(guo)(guo)(guo)(guo)、日本(ben)(ben)、印(yin)度、英國(guo)(guo)(guo)(guo)等國(guo)(guo)(guo)(guo)家(jia)(尤以(yi)日本(ben)(ben)為突出)得(de)到了(le)廣(guang)泛的(de)應(ying)用(yong)(yong)(yong)。這些(xie)國(guo)(guo)(guo)(guo)家(jia)均(jun)以(yi)本(ben)(ben)國(guo)(guo)(guo)(guo)度、區域(yu)的(de)特點(dian)確定出適合(he)其(qi)國(guo)(guo)(guo)(guo)情國(guo)(guo)(guo)(guo)力(li)的(de)中水(shui)(shui)回(hui)用(yong)(yong)(yong)技(ji)術，使(shi)中水(shui)(shui)回(hui)用(yong)(yong)(yong)技(ji)術越來(lai)越臻于完(wan)善(shan)。在中國(guo)(guo)(guo)(guo)，這一技(ji)術已受(shou)到各級政府及(ji)有關部門重(zhong)視并對建筑中水(shui)(shui)回(hui)用(yong)(yong)(yong)做了(le)大量理論研(yan)究和(he)實踐(jian)工(gong)作，在全國(guo)(guo)(guo)(guo)許多(duo)城(cheng)市如深圳、北京、青島、天津、太原等開展了(le)中水(shui)(shui)工(gong)程(cheng)的(de)運行并取得(de)了(le)顯著(zhu)的(de)效(xiao)果。我國(guo)(guo)(guo)(guo)的(de)國(guo)(guo)(guo)(guo)有工(gong)業企業和(he)部分民企，比如污染嚴(yan)重(zhong)和(he)水(shui)(shui)資源利(li)用(yong)(yong)(yong)較多(duo)的(de)企業都建成了(le)中水(shui)(shui)回(hui)用(yong)(yong)(yong)項(xiang)目(mu)，為低碳生產(chan)和(he)節能減(jian)排的(de)國(guo)(guo)(guo)(guo)家(jia)級號召(zhao)做出了(le)貢獻(xian)。
