我(wo)國有(you)著非常遼闊(kuo)的(de)(de)(de)(de)土地資源(yuan)，但是(shi)(shi)水(shui)(shui)(shui)資源(yuan)卻相對較為貧乏。在這(zhe)種(zhong)趨勢(shi)下(xia)，污水(shui)(shui)(shui)處(chu)(chu)(chu)(chu)理和污水(shui)(shui)(shui)的(de)(de)(de)(de)回用(yong)(yong)(yong)(yong)技(ji)(ji)術(shu)(shu)，就成了解決目前水(shui)(shui)(shui)資源(yuan)緊缺的(de)(de)(de)(de)一個重要(yao)的(de)(de)(de)(de)手段(duan)。污水(shui)(shui)(shui)回用(yong)(yong)(yong)(yong)的(de)(de)(de)(de)技(ji)(ji)術(shu)(shu)在我(wo)國城市污水(shui)(shui)(shui)處(chu)(chu)(chu)(chu)理中所(suo)用(yong)(yong)(yong)(yong)到的(de)(de)(de)(de)工(gong)藝(yi)，對水(shui)(shui)(shui)進行(xing)了更(geng)(geng)深層次的(de)(de)(de)(de)處(chu)(chu)(chu)(chu)理。在實際(ji)的(de)(de)(de)(de)應用(yong)(yong)(yong)(yong)中會(hui)(hui)比飲用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)處(chu)(chu)(chu)(chu)理技(ji)(ji)術(shu)(shu)更(geng)(geng)有(you)優勢(shi)，而且其(qi)所(suo)使(shi)用(yong)(yong)(yong)(yong)的(de)(de)(de)(de)工(gong)藝(yi)流(liu)程(cheng)也更(geng)(geng)加(jia)專業(ye)。從實際(ji)的(de)(de)(de)(de)應用(yong)(yong)(yong)(yong)中會(hui)(hui)比飲用(yong)(yong)(yong)(yong)水(shui)(shui)(shui) 處(chu)(chu)(chu)(chu)理技(ji)(ji)術(shu)(shu)更(geng)(geng)有(you)優勢(shi)，而且其(qi)所(suo)使(shi)用(yong)(yong)(yong)(yong)的(de)(de)(de)(de)工(gong)藝(yi)流(liu)程(cheng)也更(geng)(geng)加(jia)的(de)(de)(de)(de)專業(ye)。從現(xian)階段(duan)來看(kan)，污水(shui)(shui)(shui)回用(yong)(yong)(yong)(yong)主要(yao)是(shi)(shi)對生活用(yong)(yong)(yong)(yong)水(shui)(shui)(shui)以及工(gong)業(ye)廢(fei)水(shui)(shui)(shui)的(de)(de)(de)(de)處(chu)(chu)(chu)(chu)理。這(zhe)項技(ji)(ji)術(shu)(shu)應用(yong)(yong)(yong)(yong)的(de)(de)(de)(de)主要(yao)目的(de)(de)(de)(de)就是(shi)(shi)使(shi)廢(fei)水(shui)(shui)(shui)能(neng)夠(gou)循壞利(li)用(yong)(yong)(yong)(yong)的(de)(de)(de)(de)效果，這(zhe)也是(shi)(shi)污水(shui)(shui)(shui)回用(yong)(yong)(yong)(yong)技(ji)(ji)術(shu)(shu)的(de)(de)(de)(de)主要(yao)階段(duan)。
在(zai)進行城(cheng)(cheng)市(shi)污(wu)(wu)水(shui)治理(li)的(de)(de)過程中(zhong)，我們首先需(xu)要根據城(cheng)(cheng)市(shi)中(zhong)污(wu)(wu)水(shui)的(de)(de)特征來選擇(ze)對應的(de)(de)回用(yong)技(ji)術(shu)，現(xian)(xian)階段(duan)城(cheng)(cheng)市(shi)管網中(zhong)的(de)(de)污(wu)(wu)水(shui)，其主要污(wu)(wu)染物(wu)為有(you)機物(wu)，因此在(zai)處(chu)理(li)時可以采用(yong)微生(sheng)物(wu)的(de)(de)方式。而現(xian)(xian)階段(duan)，微生(sheng)物(wu)處(chu)理(li)技(ji)術(shu)手(shou)段(duan)，這項(xiang)技(ji)術(shu)能夠利(li)用(yong)微生(sheng)物(wu)將污(wu)(wu)水(shui)中(zhong)的(de)(de)有(you)機物(wu)進行轉化，使其成(cheng)為一種無害的(de)(de)細菌，進而實(shi)現(xian)(xian)污(wu)(wu)水(shui)處(chu)理(li)的(de)(de)最終目(mu)的(de)(de)。
