，則海水中的純水將反向滲透至淡水中。2010年6月8日，海(hai)水(shui)淡(dan)化(hua)係(xi)統(tong)投(tou)入(ru)使(shi)用(yong)，實(shi)驗(yan)室(shi)水(shui)質(zhi)分(fen)析(xi)報(bao)告(gao)顯(xian)示(shi)海(hai)水(shui)淡(dan)化(hua)係(xi)統(tong)產(chan)水(shui)各(ge)項(xiang)指(zhi)標(biao)合(he)格(ge)。紅(hong)沿(yan)河(he)項(xiang)目(mu)海(hai)水(shui)淡(dan)化(hua)係(xi)統(tong)的(de)投(tou)用(yong)
