電池(chi)行業制(zhi)備超水的(de)工藝：

1、采用離子(zi)交換方式，其流程如下(xia)： 

原(yuan)水(shui)→原(yuan)水(shui)加(jia)壓泵(beng)→多介質過(guo)濾器(qi)(qi)→活性炭過(guo)濾器(qi)(qi)→軟水(shui)器(qi)(qi)→精密過(guo)濾器(qi)(qi)→陽(yang)樹(shu)(shu)(shu)脂過(guo)濾床→陰(yin)(yin)樹(shu)(shu)(shu)脂過(guo)濾床→陰(yin)(yin)陽(yang)樹(shu)(shu)(shu)脂混床→微孔過(guo)濾器(qi)(qi)→用(yong)水(shui)點(dian)

2、采用兩級反滲(shen)透方式，其流程如下： 

原水(shui)→原水(shui)加壓(ya)泵(beng)→多介質(zhi)過(guo)濾(lv)(lv)器(qi)→活性炭過(guo)濾(lv)(lv)器(qi)→軟水(shui)器(qi)→精密過(guo)濾(lv)(lv)器(qi)→一級反(fan)滲(shen)透(tou) →PH調節→中間水(shui)箱→二級反(fan)滲(shen)透(tou)（反(fan)滲(shen)透(tou)膜表(biao)面帶(dai)正電荷）→純(chun)化水(shui)箱→純(chun)水(shui)泵(beng)→微孔過(guo)濾(lv)(lv)器(qi)→用水(shui)點

3、采(cai)用(yong)EDI方式，其流(liu)程如下： 

原水(shui)→原水(shui)加壓泵(beng)→多介質過濾(lv)器→活性炭(tan)過濾(lv)器→軟水(shui)器→精密過濾(lv)器→一級反(fan)滲(shen)透機(ji)→中間(jian)水(shui)箱→中間(jian)水(shui)泵(beng)→EDI系統→微(wei)孔過濾(lv)器→用(yong)水(shui)點 

工藝簡介：

    反滲透技術(shu)是一(yi)種高效率、低(di)能(neng)耗能(neng)、無污染的(de)(de)先(xian)進(jin)技術(shu)，主要應用于純水制備與海水淡(dan)化。反滲透技術(shu)是利(li)用壓(ya)力差為動(dong)力的(de)(de)膜分(fen)離(li)過(guo)濾技術(shu)，通過(guo)壓(ya)力差將(jiang)H2O與源水中(zhong)的(de)(de)無機(ji)鹽、重金屬離(li)子、有機(ji)物(wu)、膠體、細菌(jun)、病毒等(deng)雜(za)質嚴格(ge)分(fen)離(li)。

    EDI是一種電滲析技(ji)術和離(li)子(zi)(zi)交(jiao)(jiao)換(huan)技(ji)術相融合(he)的(de)先進技(ji)術，系統能夠通過(guo)電磁場通過(guo)陰(yin)、陽離(li)子(zi)(zi)交(jiao)(jiao)換(huan)膜對(dui)陰(yin)、陽離(li)子(zi)(zi)的(de)選擇性透過(guo)作(zuo)用(yong)與離(li)子(zi)(zi)交(jiao)(jiao)換(huan)樹脂對(dui)離(li)子(zi)(zi)的(de)交(jiao)(jiao)換(huan)作(zuo)用(yong)，在直流電場的(de)作(zuo)用(yong)下實現離(li)子(zi)(zi)的(de)定向(xiang)遷移(yi)，從(cong)而完(wan)成(cheng)水的(de)深(shen)度(du)除鹽，系統能夠完(wan)成(cheng)樹脂連續不斷的(de)自動再(zai)生，無需(xu)停機(ji)使用(yong)酸堿再(zai)生樹脂，從(cong)而能連續制(zhi)取(qu)高(gao)品質純水。

    離子交(jiao)換是用(yong)于(yu)制(zhi)取(qu)超純水(shui)的(de)一種傳統技術。離子交(jiao)換的(de)原(yuan)理是在一定條件下，依靠離子交(jiao)換劑（樹脂）本身所(suo)具有的(de)某(mou)種離子和待(dai)處理水(shui)中(zhong)同電(dian)性(xing)的(de)離子相互交(jiao)換而達到軟(ruan)化、除堿(jian)、除鹽等功能。用(yong)于(yu)深度(du)脫鹽處理，產水(shui)電(dian)阻率動態(tai)可(ke)達到18MΩ.cm。

純水處理(li)工藝之離子(zi)交換(huan)法 

    雙級反(fan)滲(shen)(shen)(shen)透(tou)(tou)是將兩套反(fan)滲(shen)(shen)(shen)透(tou)(tou)裝置串聯，一級反(fan)滲(shen)(shen)(shen)透(tou)(tou)的產(chan)水(shui)作為二級反(fan)滲(shen)(shen)(shen)透(tou)(tou)的入(ru)水(shui)。由于(yu)一級反(fan)滲(shen)(shen)(shen)透(tou)(tou)的產(chan)水(shui)水(shui)質遠遠好于(yu)自來水(shui)，所以二級反(fan)滲(shen)(shen)(shen)透(tou)(tou)產(chan)水(shui)的水(shui)質較(jiao)單(dan)級RO系統產(chan)水(shui)水(shui)質更(geng)佳(jia)，離子(zi)、有機(ji)物和熱源(yuan)含(han)量更(geng)低(di)。
