     一、概述

      隨著(zhu)人們對生(sheng)(sheng)活(huo)(huo)的追(zhui)求,經(jing)濟的發展(zhan),環(huan)境的惡化,不(bu)僅(jin)造成(cheng)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)環(huan)境的污(wu)(wu)染(ran),更加劇了水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)資(zi)源的緊(jin)張,許(xu)多(duo)地(di)區出(chu)現了不(bu)同程度的水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)資(zi)源危機(ji),甚至出(chu)現了嚴重缺水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui),使(shi)生(sheng)(sheng)活(huo)(huo)用(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)都(dou)難以滿足。怎樣節(jie)約用(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)呢(ni)?中(zhong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)介于上水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)和下水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)之間,也(ye)叫“再生(sheng)(sheng)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)”,是(shi)指城(cheng)(cheng)市(shi)污(wu)(wu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)或生(sheng)(sheng)活(huo)(huo)污(wu)(wu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)經(jing)處(chu)理達(da)標后,在(zai)一定的范圍內(nei)重復使(shi)用(yong)(yong)的非飲(yin)用(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)。中(zhong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)主要用(yong)(yong)于農(nong)田的澆灌,城(cheng)(cheng)市(shi)的綠化,工業(ye)用(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui),廁所(suo)沖洗,道路保潔。對于淡水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)資(zi)源缺乏,城(cheng)(cheng)市(shi)供水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)嚴重不(bu)足的缺水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)地(di)區,采用(yong)(yong)中(zhong)水(shui)(shui)(shui)(shui)(sh颤介ui)(shui)(shui)(shui)技術既能節(jie)約水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)源,又能使(shi)污(wu)(wu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)無(wu)害化,是(shi)防治水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)污(wu)(wu)染(ran)的重要途徑,也(ye)是(shi)我國目前及將來長時間內(nei)重點推廣的新(xin)技術、新(xin)工藝。因(yin)此中(zhong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)被稱為第二水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)源,達(da)到節(jie)約用(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)的理念。東莞市(shi)高達(da)環(huan)保科技有(you)限公司所(suo)研發生(sheng)(sheng)產的中(zhong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)回用(yong)(yong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)處(chu)理系統,是(shi)將廢(fei)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)中(zhong)的各種有(you)微生(sheng)(sheng)物(wu)和有(you)機(ji)物(wu)吸附去除使(shi)廢(fei)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)得(de)到凈化的高新(xin)環(huan)保產品。

      二、中水回用系統按照其不同的用途可分為幾大類


     靡砌 (1)建(jian)筑(zhu)中(zhong)水系統(tong),在大型建(jian)筑(zhu)或建(jian)筑(zhu)群中(zhong)建(jian)立的系統(tong),

      (2)區(qu)域(yu)中水(shui)系統(tong),在建筑小區(qu)、校(xiao)園內建立(li)的(de)建炫中水(shui)系統(tong);

      (3)城(cheng)(cheng)市(shi)(shi)中水(shui)系(xi)統(tong),又稱為污水(shui)回(hui)用系(xi)統(tong),是在(zai)整個城(cheng)(cheng)市(shi)(shi)規(gui)劃(hua庭离)區建立的(de)中水(shui)回(hui)用系(xi)統(tong)。

      (4)一(yi)種(zhong)是將其處理到飲用(yong)(yong)水的標(biao)準(zhun)而直(zhi)接(jie)回用(yong)(yong)到日常生活中,即實現水資惧笛源(yuan)直(zhi)接(jie)循(xun)環利用(yong)(yong),這(zhe)種(zhong)處理方式適(shi)用(yong)(yong)于(yu)水資源(yuan)極度(du)缺乏的地區,但(dan)投資高,工藝復雜

      (5) 另一(yi)種是將其(qi)處理(li)到非(fei)飲(yin)用(yong)水的(de)標準,主(z停搜hu)要(yao)用(yong)于不與人(ren)體直接接觸的(de)用(yong)水,如便器的(妓小de)沖(chong)洗(xi),地面、汽車(che)清洗(xi),綠化(hua)澆(jiao)灑,消防,工業普通(tong)(tong)用(yong)水等,這是通(tong)(tong)常(chang)的(de)中(zhong)水處理(li)方式。

      (6)工業上可以利用中水回用技術將達到外排標準的工業污水進行再處理,一般會加上軟化器,RO,EDI/混床等設備使其達到軟化水,純化水,超純水水平,可以進行工業循環再利用,達到節約資本,保護環境的目的。

      三、中水回用處理方法


      1.生物(wu)(wu)化(hua)(hua)學法(fa)(fa)(fa)(簡稱生化(hua)(hua)法(fa)(fa)(fa))利用自然(ran)界存生的(de)各種細菌微(wei)生物(wu)(wu)的(de)吸附、氧(yang)(yang)化(hua)(hua)分解污水中的(de)有機物(wu)(wu),包易带括(kuo)好氧床捡(yang)(yang)和(he)厭氧(yang)(yang)微(wei)生物(wu)(wu)處(chu)理(li),一般以(yi)好氧(yang)(yang)處(chu)理(li)較多(duo),化(hua)(hua)成無(wu)害物(wu)(wu)質,使廢水得以(yi)凈(jing)化(hua)(hua)。生物(wu)(wu)化(hua)(hua)學法(fa)(fa)(fa)可以(yi)分活性污泥法(fa)(fa)(fa)、生物(wu)(wu)膜(mo)法(fa)(fa)(fa)、生物(wu)(wu)氧(yang)(yang)化(hua)(hua)塔、土地處(chu)理(li)系統、厭氧(yang)(yang)生物(wu)(wu)處(chu)理(li) 法(fa)(fa)(fa)等方法(fa)(fa)(fa)。

      工藝;原水(shui)&ra寞缝rr;格柵→調節池→接觸氧化(hua)池→沉(chen)淀地→過(guo)濾→消毒→出水(shui)

      2.物(wu)理(li)化(hua)學法是指(zhi)由物(wu)理(li)方(fang)法和(he)(he)化(hua)學方(fang)法組(zu鞭莽)成的廢水(shui)處理(li)系統,或指(zhi)包括(kuo)物(wu)理(li)過程和(he)(he)化(hua)學過程的單項處理(li)方(fang)法,如浮選、吹脫(tuo)、結晶、吸(xi)附(fu)、萃取(qu)、電(dian)解、電(dian)滲(shen)析、離子交換、反滲(shen)透等。

      工藝奋杀;原水(shui)→格柵→調節(jie)池→絮(xu)凝沉淀池→超濾膜→消毒→出水(shui)。

      3.膜(mo)生(sheng)物反(fan)應器技術(shu)(shu)(物化生(sheng)化結合法)膜(mo)生(sheng)物反(fan)應器 (簡(jian)稱MBR)是(shi)將生(sheng)物降解作用與(yu)费武膜(mo)的高(gao)(gao)效(xiao)分離技術(shu)(shu)結合而成的一種新(xin)型高(gao)(gao)效(xiao)的污水(shu米同i)處(chu)理與(yu)回用工藝(yi)

      工藝;原水→格柵→調節池→活性污泥池→超濾膜→消毒→出水。(一體式)

      四、 中水回用的水質標準


      1、目前(qian)我國(guo)還沒有中(zhong)水(shui)(shui)回(hui)用(yong)(yong)的(de)統一(yi)標(biao)(biao)準(zhun)(zhun)(zhun)(zhun),因此在(zai)中(zhong)水(shui)(shui)回(hui)用(yong)(yong)時水(shui)(shui)質標(biao)(biao)準(zhun)(zh窃睛un)(zhun)(zhun)一(yi)般(ban)參考(kao)相(xiang)關的(de)行(xing)業(ye)標(biao)(biao)準(zhun)(zhun)(zhun)(zhun)或地方中(zhong)水(shui)(shui)回(hui)用(yong)(yong)標(biao)(biao)準(zhun)(zhun)(zhun)(zhun),用(yong)(yong)于(yu)(yu)一(yi)般(ban)景(jing)觀生(sheng)(sheng)態用(yong)(yong)水(shui)(shui)應符(fu)合(he)(he)《再(zai)生(sheng)(sheng)水(shui)(shui)回(hui)用(yong)(yong)于(yu)(yu)景(jing)觀水(shui)(shui)體的(de)水(shui)(shui)質標(biao)(biao)準(zhun)(z读畴hun)(zhun)(zhun)》(CJ/T95-2000),用(yong)(yong)于(yu)(yu)生(sheng)(sheng)活雜(za)(za)用(yong)(yong)水(shui)(shui)應符(fu)合(he)(he)建設(she)部(bu)《生(sheng)(sheng)活雜(za)(za)用(yong)(yong)水(shui)(shui)水(shui)(shui)質標(biao)(biao)準(zhun)(zhun)(zhun)(zhun)》(CJ/48-1999),用(yong)(yong)于(yu)(yu)工業(ye)循環冷(leng)卻(que)水(shui)(shui)應符(fu)合(he)(he)《工業(ye)循環水(shui)(shui)冷(leng)卻(que)設(she)計(ji)規范》(GB/T50102-2003)。

      2、我公司響(x挖函iang)應國家節約能(neng)源(yuan)、節能(neng)降耗的要求(qiu)(qiu),憑借雄厚(hou)的技術(shu)實力(li)、豐富的工程經驗(yan)和專有(you)技術(shu)可(ke)承攬各種污廢水(shui)(shui)處理(li)工程,出水(shui)(shui)達到回用(yong)(yong)要求(qiu)(qiu),用(yong)(yong)于(yu)城市景觀和沖洗馬(ma)路、車輛、廁所及綠化,甚至消(xiao)防(fang),實現國家節水(shui)(shui)循(xun)環(huan)利用(yong)(yong)水(shui)(shui)資(zi)源(yuan)的目(mu)標。本公司所擁有(you)的自然循(xun)環(huan)方式(shi)污水(shui)(shui)處理(li)技術(shu)尤其(qi)適(shi)合用(yong)(yong)于(yu)城市小(xiao)區(qu)中水(shui)(shui)回用(yong)(yong),共(gong)同構建節約型環(huan)保社(she)區(qu)。

      五、購買污水處理設備需要注意什么?


      1、了解(jie)設備所用材料

      通常地埋(mai)式設備所(suo)用(yong)(yong)材(cai)料(liao)有玻璃鋼(gang)與碳鋼(gang)兩(liang)種類型(xing),在購買(mai)設備時需(xu)要問(wen)清供(gon铣签g)應商所(suo)用(yong)(yong)材(cai)料(liao),在工藝及其(qi)他(ta)條件相同時,材(cai)料(liao)不同價格將有很大差異。

      2、去供應商成功案例現場觀(guan)看(kan)效(xiao)果

      一切用事(shi)實說話,無(wu)論為你提桑脆供(gong)設(she)備(bei)的(de)(de)供(gong)應(ying)商(shang)如何介紹設(she)備(bei)的(de)(de)優(you)越(yue)性能,都應(ying)該讓供(gong)應(ying)商(shang)提供(gong)以前(qian)的(de)(de)成功案例,然后派人去(qu)實地(di)考察其(qi)現場污水處理效(xiao)果。雖然可能會(hui)耽誤部分時(shi)間(jian),但這確是非常的(de)(de)關鍵(jian)。

      3、約(yue)定出水(shui)執行標準

      很(hen)多單位在購買地埋式污(wu)(wu)水處理(li)設備時(s轴箕hi)對污(wu)(wu)水處理(li)達標標準沒在合同(tong)中注明,在后期環保要求提(ti)高前提(ti)下(xia),會(hui)導(dao)致糾紛。因為處理(li)程度不(bu)同(tong),污(wu)(wu)水處理(li)成本會(hui)有很(hen)大差異。

      4、在購買前多對比、簽訂(ding)合同(tong)并注明付款流程

      多(duo)選擇幾家供應商(shan匠祝g)做參考,然后對(dui)其采用工藝、成功案例、價格等因(yin)素進(jin)行(xing)綜合對(dui)比(bi)。

      支(zhi)付定金前簽訂正式合同(tong)、并約定交貨、調(diao)試(shi)藐断及付款流程。
