摘要
介绍了目前中国水资源和膜工业现状。目前 ,世界水污染日益严重 ,水资源日益短缺。中国有 6 6 0个城市 ,36 0个城市缺水 ,110个城市严重缺水 ,4 0个城市极度缺水。有些专家预测 ,水资源将会成为许多地区冲突和国际战争的根源。中国的水污染十分严重 ,有 4 6 .5%的河流受到了污染 ,77%的污水未经处理被直接排放。膜技术在水处理方面有着独特的优势。中东不少国家使用反渗透技术进行海水淡化 ,世界 5大海水淡化工厂有 4家在中东的沙特。利用膜技术实现分质供水是提高人们饮水质量的重要措施。膜技术用于城市污水处理既可以减少污染 ,也可以节约资源。中国膜研究人员和膜公司很多 ,这些年发展也特别快 ,但在实力上和规模上与世界先进水平还有差距 ,有待进一步提高。
The paper presents 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 conflicts 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 presents some data of Chinese membrane research and manufacture.
