Abstract : The paper present s a general summary on the state of the water resource and membrane industry of China. Now the water pollution is becoming more grave , and the water resource is shorter and shorter in the earth. China has 660 cities ,360 cities of them are short of water. The situation in 110 cities is serious , and the situation in 40 cities is dangerous. It was predicted that the water could be a main cause of local conflict s and international wars. The water pollution in China is also very astonished. 77 % untreated wastewater is discharged ,and 46. 6 % river is polluted. Membrane is a clean production technology ,which could be used to improve the quality of drink water ,treat the waste to reduce the pollution and save the water resource. China has a lot of researchers and research institute on membrane. The paper present s some data of Chinese membrane research and manufacture.
Key words : membrane ; water treatment ; environment protection

摘 要： 這篇文章簡單介紹了目前中國水資源和膜工業(yè)的現(xiàn)狀。目前，世界水污染日益嚴(yán)重，水資源日益短缺。中國有660 個(gè)城市，360 個(gè)城市缺水，110 個(gè)城市嚴(yán)重缺水，40 個(gè)城市極度缺水。有些專家預(yù)測，水資源將會(huì)成為許多地區(qū)沖突和國際戰(zhàn)爭的根源。中國的水污染十分嚴(yán)重， 有46. 5 %的河流受到了污染，77 %的污水未經(jīng)處理被直接排放。膜技術(shù)在水處理方面有著獨(dú)特的優(yōu)勢。膜技術(shù)是一種可以用來提高人們飲用水質(zhì)量、處理污水節(jié)約水資源的清潔技術(shù)。中國也有眾多的膜研究人員和膜公司。這篇文章介紹了中國膜技術(shù)的研究和膜制造的一些數(shù)據(jù)。
