院士談《給水排水工程》專業
我叫李圭白，是給水排水工程學科的中國工程院院士，歡迎中學畢業生報考《給水排水工程》專業。

給水排水工程以水的社會循環為研究內容
●地球淡水的循環可區分為水的自然循環和水的社會循環
●水的自然循環－水從海洋蒸發，被氣流輸送到大陸，以雨、雪等降水形式落到地面，形成地表水（江、河、湖、庫）和地下水，最終又流回海洋。水的自然循環及其調控是水利工程的研究內容。
●水的社會循環－人類社會為滿足人們生活飲用和生產（工農業）的需要而從自然水體取水，經必要的處理以改善水質，然后輸送到
Academy of Sciences on "Water Engineering"
My name is Li Gui-bai, a water supply and drainage engineering disciplines of the Chinese Academy of Engineering, welcomed the graduates to attend high school, "Water Engineering".

Water Supply and Drainage to study the water content of the social circle
● Earth's water cycle can be divided into the natural water cycle and water, social circle
● natural circulation of water - water evaporation from the ocean, was air transported to the mainland, rain, snow and other forms of precipitation fell on the ground, surface water (rivers, lakes and reservoirs) and groundwater, and eventually went back to the sea. And regulation of the natural cycle of water is the Water of the content.
● Water's social circle - of human society to meet the people's lives for drinking and production (agriculture and industry) needs water from natural water bodies, subject to necessary treatment to improve water quality, and delivery to
