中水回用處理

中(zhong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)回(hui)用(yong)，是(shi)解決城(cheng)市水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)資源(yuan)危機(ji)的(de)(de)(de)(de)重要途徑，也是(shi)協調城(cheng)市水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)資源(yuan)與水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)環境(jing)的(de)(de)(de)(de)根本(ben)出(chu)路，生活(huo)污(wu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)處(chu)理(li)(li)回(hui)用(yong)，既(ji)能減小對地下水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)的(de)(de)(de)(de)開采，又能給我們帶來(lai)一定的(de)(de)(de)(de)經濟效益。中(zhong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)是(shi)指各種排水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)經處(chu)理(li)(li)后，達到(dao)規定的(de)(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)質(zhi)標(biao)(biao)準(zhun)，可在生活(huo)、市政、環境(jing)等范圍內雜用(yong)的(de)(de)(de)(de)非飲用(yong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)。因(yin)為它的(de)(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)質(zhi)指標(biao)(biao)低于生活(huo)飲用(yong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)的(de)(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)質(zhi)標(biao)(biao)準(zhun)，但又高于允許排放的(de)(de)(de)(de)污(wu)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)的(de)(de)(de)(de)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)質(zhi)標(biao)(biao)準(zhun)，處(chu)于二者之間，所以叫做“中(zhong)水(shui)(shui)(shui)(shui)(shui)(shui)(shui)(shui)”。

由于“水(shui)(shui)(shui)(shui)危(wei)機”的困(kun)擾，許(xu)多(duo)國家和地(di)區積極著(zhu)手鞏固和加強節(jie)水(shui)(shui)(shui)(shui)意識(shi)以(yi)及研究城(cheng)市(shi)(shi)廢(fei)水(shui)(shui)(shui)(shui)再(zai)生(sheng)與回(hui)(hui)用(yong)(yong)(yong)工(gong)作(zuo)。城(cheng)市(shi)(shi)污(wu)(wu)(wu)水(shui)(shui)(shui)(shui)回(hui)(hui)用(yong)(yong)(yong)就(jiu)是(shi)將(jiang)城(cheng)市(shi)(shi)居民(min)生(sheng)活(huo)(huo)及生(sheng)產中(zhong)使(shi)用(yong)(yong)(yong)過的水(shui)(shui)(shui)(shui)經過處理(li)后(hou)回(hui)(hui)用(yong)(yong)(yong)。有兩種(zhong)不(bu)(bu)同程(cheng)度的回(hui)(hui)用(yong)(yong)(yong)：一種(zhong)是(shi)將(jiang)污(wu)(wu)(wu)水(shui)(shui)(shui)(shui)處理(li)到(dao)可飲(yin)用(yong)(yong)(yong)的程(cheng)度，而另(ling)一種(zhong)則是(shi)將(jiang)污(wu)(wu)(wu)水(shui)(shui)(shui)(shui)處理(li)到(dao)非飲(yin)用(yong)(yong)(yong)的程(cheng)度。對于前(qian)一種(zhong)，因(yin)其(qi)投資較高(gao)、工(gong)藝復(fu)雜，非特缺水(shui)(shui)(shui)(shui)地(di)區一般不(bu)(bu)常(chang)采用(yong)(yong)(yong)。多(duo)數(shu)國家則是(shi)將(jiang)污(wu)(wu)(wu)水(shui)(shui)(shui)(shui)處理(li)到(dao)非飲(yin)用(yong)(yong)(yong)的程(cheng)度，在此(ci)引出(chu)了中(zhong)水(shui)(shui)(shui)(shui)概念。中(zhong)水(shui)(shui)(shui)(shui)也就(jiu)是(shi)將(jiang)人們在生(sheng)活(huo)(huo)和生(sheng)產中(zhong)用(yong)(yong)(yong)過的優質雜排水(shui)(shui)(shui)(shui)(不(bu)(bu)含糞便和廚房排水(shui)(shui)(shui)(shui))、雜排水(shui)(shui)(shui)(shui)(不(bu)(bu)含糞便污(wu)(wu)(wu)水(shui)(shui)(shui)(shui))以(yi)及生(sheng)活(huo)(huo)污(wu)(wu)(wu)(廢(fei))水(shui)(shui)(shui)(shui)經集流再(zai)生(sheng)處理(li)后(hou)回(hui)(hui)用(yong)(yong)(yong)，充(chong)當地(di)面清潔、澆花(hua)、洗車、空調冷(leng)卻、沖(chong)洗便器、消防等不(bu)(bu)與人體直接接觸的雜用(yong)(yong)(yong)水(shui)(shui)(shui)(shui)。
