摘要：文(wen)中(zhong)(zhong)在闡述中(zhong)(zhong)水回(hui)用(yong)相關概念的(de)基(ji)礎上，對我國(guo)(guo)中(zhong)(zhong)水回(hui)用(yong)的(de)前(qian)(qian)景(jing)及(ji)約束性(xing)因(yin)素(su)進(jin)行了分析(xi)，分析(xi)表明(ming)，中(zhong)(zhong)水回(hui)用(yong)在中(zhong)(zhong)國(guo)(guo)前(qian)(qian)景(jing)廣闊(kuo)，制約中(zhong)(zhong)國(guo)(guo)中(zhong)(zhong)水回(hui)用(yong)的(de)主要因(yin)素(su)為中(zhong)(zhong)水價格過高，相關法律法規及(ji)標準缺乏，建(jian)設(she)及(ji)運營資金不足及(ji)公(gong)眾意識缺乏等。

關鍵詞：中(zhong)水(shui)回(hui)用；前(qian)景；約束性(xing)因素

中水(shui)特指(zhi)(zhi)城(cheng)市污(wu)水(shui)或生(sheng)活污(wu)水(shui)經處理后達到一(yi)定的水(shui)質標(biao)準，可在一(yi)定范圍內重(zhong)復(fu)使用(yong)(yong)的非飲(yin)用(yong)(yong)水(shui)，其水(shui)質指(zhi)(zhi)標(biao)低于飲(yin)用(yong)(yong)水(shui)水(shui)質標(biao)準，高于污(wu)水(shui)允許排(pai)入地(di)面(mian)水(shui)體(ti)排(pai)放標(biao)準。

中(zhong)水(shui)(shui)(shui)(shui)(shui)原水(shui)(shui)(shui)(shui)(shui)是(shi)指選擇作(zuo)中(zhong)水(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)源(yuan)而未經(jing)處理的水(shui)(shui)(shui)(shui)(shui)，中(zhong)水(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)源(yuan)的選用應根據原排水(shui)(shui)(shui)(shui)(shui)的水(shui)(shui)(shui)(shui)(shui)質、水(shui)(shui)(shui)(shui)(shui)量、排水(shui)(shui)(shui)(shui)(shui)狀況和中(zhong)水(shui)(shui)(shui)(shui)(shui)所需的水(shui)(shui)(shui)(shui)(shui)質、水(shui)(shui)(shui)(shui)(shui)量確定。中(zhong)水(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)源(yuan)一般為生(sheng)活(huo)廢水(shui)(shui)(shui)(shui)(shui)、生(sheng)活(huo)污(wu)水(shui)(shui)(shui)(shui)(shui)、冷卻水(shui)(shui)(shui)(shui)(shui)等(deng)。醫院污(wu)水(shui)(shui)(shui)(shui)(shui)、生(sheng)產污(wu)水(shui)(shui)(shui)(shui)(shui)等(deng)由于含有(you)多種(zhong)病菌(jun)、病毒及其(qi)他有(you)害物質，成(cheng)分較(jiao)為復(fu)雜，不宜作(zuo)中(zhong)水(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)源(yuan)。

按(an)照規模，中水(shui)(shui)系統從小到大可以分(fen)為三類，分(fen)別是(shi)：單幢建(jian)筑中水(shui)(shui)系統，小區中水(shui)(shui)系統以及城市中水(shui)(shui)系統。

中(zhong)(zhong)水(shui)(shui)處(chu)(chu)理(li)(li)方(fang)法(fa)是隨(sui)著水(shui)(shui)處(chu)(chu)理(li)(li)技術的(de)發(fa)展(zhan)而(er)發(fa)展(zhan)的(de)，由(you)于處(chu)(chu)理(li)(li)的(de)對象為污水(shui)(shui)，而(er)處(chu)(chu)理(li)(li)后的(de)水(shui)(shui)質(zhi)要達到回(hui)用的(de)目的(de)，并符合國家的(de)有關水(shui)(shui)質(zhi)標(biao)準，因此(ci)，中(zhong)(zhong)水(shui)(shui)的(de)處(chu)(chu)理(li)(li)技術，按處(chu)(chu)理(li)(li)機理(li)(li)不同(tong)可分為物理(li)(li)化學(xue)處(chu)(chu)理(li)(li)法(fa)、生物處(chu)(chu)理(li)(li)法(fa)、膜處(chu)(chu)理(li)(li)法(fa)三大(da)類(lei)。

文(wen)中(zhong)主要(yao)分析(xi)了(le)我國中(zhong)水回用的前(qian)景及約(yue)束性(xing)因素，為(wei)中(zhong)國中(zhong)水的發展提(ti)供(gong)思(si)路。
