關健詞建筑節約用水超壓出流熱水循環方式管閥泄漏中水系統雨水回收利用

我國水資源總量居世界第六位,但按人均水資源量計量,人均占有量為 2500m3,僅為世界人均水量的 1/4,世界排名第 110 位,是個人均水資源嚴重匾乏的國家。當前,在全國 668 座城市中,有 400 多座城市缺水,年缺水量達 60 多億 m3。長期以來,在“水資源取之不盡,用之不竭”的傳統價值觀念影響下,水資源被長期無償利用,導致人們的節水意識低下,造成了巨大的水資源浪費和水資源非持續開發利用。水資源日益短缺,合理開發水資源、利用水資源、保護生態環境,維護人與自然的和諧,已經成為人類共同的使命。本文就建筑給排水設計中所能采取的節水措施,探討如下。

3 減少管道和閥門泄漏浪費

管道、閥門的選材及安裝質量等導致大量的水消失于無形。經常都能看到路邊的給水管道在管子接縫處及法蘭、閥門連接處滋滋的往外冒水。埋在地下的看不見的更不知道有多少。用戶們反映浮球閥經常損壞、漏水,不論是用于水池、水箱的還是馬桶上使用的,其質量的低劣直接導致大量水從溢流管流出。解決此問題需合理選用優質的管道和閥門,并在施工以及后期物業管理過程中嚴格管理。
