1. 食(shi)品及(ji)飲料類水質標準

   原則上(shang)，一般采用(yong)生活(huo)飲(yin)用(yong)水(shui)(shui)(shui)水(shui)(shui)(shui)質(zhi)標(biao)(biao)準。但近(jin)年隨著人民生活(huo)水(shui)(shui)(shui)平的(de)提(ti)高，對水(shui)(shui)(shui)質(zhi)的(de)要求越來越高，出現(xian)了(le)小區、罐(guan)裝(zhuang)水(shui)(shui)(shui)（桶裝(zhuang)水(shui)(shui)(shui)、瓶裝(zhuang)水(shui)(shui)(shui)）等各種(zhong)高質(zhi)飲(yin)水(shui)(shui)(shui)。這些飲(yin)水(shui)(shui)(shui)的(de)水(shui)(shui)(shui)質(zhi)標(biao)(biao)準在(zai)生活(huo)飲(yin)用(yong)水(shui)(shui)(shui)水(shui)(shui)(shui)質(zhi)標(biao)(biao)準的(de)基礎上(shang)，又有所提(ti)高。

2.城市雜用水(shui)水(shui)質標準

城市雜用(yong)水(shui)(shui)(shui)是(shi)城市和人們日常生(sheng)活所經常涉及(ji)的(de)一類用(yong)水(shui)(shui)(shui)，主要(yao)包括廁(ce)所便器(qi)沖洗、城市綠化、洗車、掃(sao)除(chu)、建筑施工及(ji)有同樣水(shui)(shui)(shui)質(zhi)要(yao)求的(de)其他用(yong)途(tu)的(de)水(shui)(shui)(shui)。

過去傳統上采用(yong)(yong)(yong)城(cheng)(cheng)市管網(wang)水(shui)(shui)(shui)作為(wei)城(cheng)(cheng)市雜(za)(za)用(yong)(yong)(yong)水(shui)(shui)(shui)，對(dui)(dui)水(shui)(shui)(shui)質不做特(te)殊(shu)規(gui)定(ding)。隨著人(ren)們(men)對(dui)(dui)水(shui)(shui)(shui)危機的(de)憂患意識增強，節水(shui)(shui)(shui)措施逐步得到落(luo)實(shi)(shi)，污(wu)(wu)(wu)水(shui)(shui)(shui)資(zi)源化的(de)興起，人(ren)們(men)越來越多的(de)以城(cheng)(cheng)市污(wu)(wu)(wu)水(shui)(shui)(shui)再生回用(yong)(yong)(yong)、雨水(shui)(shui)(shui)、海水(shui)(shui)(shui)或(huo)按水(shui)(shui)(shui)質要(yao)求(qiu)的(de)不同將城(cheng)(cheng)市管網(wang)水(shui)(shui)(shui)實(shi)(shi)行循(xun)序利用(yong)(yong)(yong)，作為(wei)城(cheng)(cheng)市雜(za)(za)用(yong)(yong)(yong)水(shui)(shui)(shui)。雖然城(cheng)(cheng)市雜(za)(za)用(yong)(yong)(yong)水(shui)(shui)(shui)的(de)水(shui)(shui)(shui)質要(yao)求(qiu)沒有飲用(yong)(yong)(yong)水(shui)(shui)(shui)那樣高，但是也應滿足(zu)使(shi)用(yong)(yong)(yong)中(zhong)的(de)一定(ding)要(yao)求(qiu)，做到既利用(yong)(yong)(yong)污(wu)(wu)(wu)水(shui)(shui)(shui)、雨水(shui)(shui)(shui)等資(zi)源，又能(neng)切實(shi)(shi)保證安全與適用(yong)(yong)(yong)。為(wei)此，我國制定(ding)了(le) 《城市雜用水水質標準》GB/T 18920—2002。

3. 游泳池用水水質標準(zhun)

游泳(yong)(yong)池用水(shui)(shui)與人(ren)體(ti)直接(jie)接(jie)觸，也關系(xi)到人(ren)的(de)身體(ti)健康。我國的(de)相應標準規定游泳(yong)(yong)池補充水(shui)(shui)應符合(he)生活飲用水(shui)(shui)水(shui)(shui)質標準，同時根據(ju)游泳(yong)(yong)池用水(shui)(shui)的(de)特殊情況，對于池內水(shui)(shui)質有一些補充規定。

4.水(shui)質標(biao)準

工業(ye)種類繁多(duo)，對(dui)用水的(de)要(yao)(yao)求(qiu)也不(bu)盡相問(wen)，例如(ru)電子工業(ye)對(dui)水質要(yao)(yao)求(qiu)極為嚴(yan)格。要(yao)(yao)求(qiu)使用純水、超純水；而一般工業(ye)冷卻用水對(dui)水質要(yao)(yao)求(qiu)則十(shi)分(fen)寬松。容許(xu)渾(hun)濁度達到50~100NTU。 因此各從保證產(chan)品(pin)質(zhi)量(liang)和(he)保障(zhang)生產(chan)正(zheng)常運行的(de)角度，制(zhi)定(ding)相應(ying)的(de)水質(zhi)標準。
