                雨水收集意義

                 

                了解雨水收集  

                    我國(guó)真正意義上的城市雨水資源化利用研究和應(yīng)用開(kāi)始于20世紀(jì)80年代后期,當(dāng)時(shí),面對(duì)日益緊張的城市供水形勢(shì),國(guó)內(nèi)個(gè)別城市開(kāi)始考慮雨水資源的收集利用問(wèn)題,嘗試著在一些建筑物上安裝雨水收集系統(tǒng),但是,由于沒(méi)有配套的雨水處理和回用系統(tǒng),實(shí)際利用成效不大。

                 

                   進(jìn)入21世紀(jì)以來(lái),我國(guó)城市雨水資源化利用的進(jìn)程明顯加快,技術(shù)水平也迅速提高。2001年國(guó)務(wù)院批準(zhǔn)了包含有雨洪利用規(guī)劃內(nèi)容的“21世紀(jì)初期首都水資源可持續(xù)利用規(guī)劃”,推動(dòng)北京市的城市雨水資源化利用走在了全國(guó)前列。

                 

                   把雨水收集起來(lái),經(jīng)簡(jiǎn)單處理后用于土地入滲補(bǔ)充地下水、城市的綠化澆灌、沖洗馬路、消防、洗車、沖廁、洗衣服及其他生活用途,既能減少城市雨洪危害、減輕城市排水和河道行洪壓力,又能緩解城市水資源短缺的危機(jī)。

                 

                雨水收集應(yīng)用 

                 

                雨水收集現(xiàn)狀與前景

                 

                   為緩解城市內(nèi)澇,建設(shè)綠色城市,習(xí)主席提出建設(shè)海綿城市,國(guó)內(nèi)各地區(qū)也紛紛推出相關(guān)政策以推進(jìn)海綿城市建設(shè)。

                   隨著全域推進(jìn)海綿城市建設(shè)政策實(shí)施,海綿城市建設(shè)迎來(lái)一波熱潮,內(nèi)澇危機(jī)頻現(xiàn)也將催生建設(shè)海綿城市的迫切需求,政策和試點(diǎn)不斷超預(yù)期反映國(guó)家層面的堅(jiān)定態(tài)度,有望爆發(fā)一波海綿城市的投資熱潮。
