Based on the research and actual conditions abroad for life in the water, and points out that structural analysis only consider a few of water quality living small distinguish qualitative water supply and foreign common the difference between high quality water supply and limitations. And according to the distribution of urban water consumption and water quality requirements, that the above high quality water supply method is not suitable for urban integral water supply requirements. But high quality water pipeline supply in life, as in the district water for the transitional measures to alleviate contradictions, still has a positive meaning.
相關(guān)簡(jiǎn)介 ：僅考慮滿足飲用水量需求的管道分質(zhì)供水，不是發(fā)達(dá)國(guó)家的先進(jìn)經(jīng)驗(yàn)和可接受的做法。這種分質(zhì)供水只能在有限程度上提高居民用水的安全性，是受目前經(jīng)濟(jì)實(shí)力限制而采取的一種過(guò)渡性方法。這此方法在某些城市的生活小區(qū)試行，有一定的積極意義；在整個(gè)城市實(shí)行是不合理的，存在著顯而易見(jiàn)的不良后果。目前這種少量飲水單獨(dú)用管道供應(yīng)的做法受關(guān)注，與商業(yè)利益驅(qū)動(dòng)不無(wú)關(guān)系。長(zhǎng)遠(yuǎn)來(lái)看，改善飲用水水質(zhì)的基本途徑是提高城市主體供水系統(tǒng)的水質(zhì)。實(shí)現(xiàn)這一目標(biāo)，不僅需要加強(qiáng)水源保護(hù)，改進(jìn)水廠處理工藝，改善輸配水系統(tǒng)的技術(shù)狀態(tài)，還需要改革城市代供水行業(yè)的運(yùn)行機(jī)制，逐步實(shí)現(xiàn)水價(jià)的市場(chǎng)化。
