1 Introduction

Water is a main resource for our human being ,but the problem of water is more serious than before.

China is a developing country while it s economy goes forward rapidly. However , along with the development of economy , the eco - environmental problem is becoming worse and worse , such as shortage of resources , ecological damage , environmental pollution and etc. all these are bound to have fatal impact s on the improvement of our living standard and on the substantial development of economy. Now the central government is focusing on the development over the western part of China , iane reactor were developed , and have been put into application in the fields of energy , electronics ,petroleum , petrochemical , pharmacy , heavy industry , light industry , food and brewery industry , people’s daily life and the environmental protection. Especially in the water treatment , the application of membrane technology turns wider and wider , and plays an increasingly important role. 2 The state of water resource and water pollution in China

In range of environmental problems , water problem is extremely severe. There are one third of people on the earth facing with how to solve the shortage of water and how to treat the wastewater. This number will be doubled in the next 30 years. It is forecast by some experts that water , rather than oil , is going to be the main cause of conflicts regionally even globally.

There are 660 cities in China. Among them , more than 360 are short of water and 110 are in urgent situation. Further more , 40 cities are in the list of the cities that are ext remely short of water. It is estimate999 , 46. 5 % of rivers were polluted in 100 000 km monitored rivers , but the wastewater treated ratio was only 23 %. [1 ]

Water pollution has become the obstacle of economic development and social progress. In Sanxia reservoir of Yangzi River , there are 21 counties discharging wastes into Yangzi River. The height of the float above water reaches 2～4 m , sometimes 6. 5 m. It has directly affected the work of Ge Zhou Ba water power station. It causes frequent breakdown of Erjiang power station. The worst case happened was that once a time the float caused severe power plants breakdown with an electricity loss of 14 000 r quality in Yangteng Lake drops to grade 3 from grade 2 , which causes the water undrinkable.

3 State of membrane industry

China has a lot of research unit s and researchers on membrane. The research on electric dialysis and ion exchange membrane began in 1958[2 ] . RO membrane began in 1965 and UF membrane in 1mbrane , gas membrane , inorganic membrane , pervaporation membrane and liquid membrane.

Although the membrane industry of China is not big , it grows up very quickly. According to the statistical data in 1997 , there were 13 big companies of membrane with the output over ＄1. 2 million in China ( Tab. 1) . The output of solo membrane was ＄45 million , within which the imported value was ＄27 million. The industrial output relevant to membrane was estimated ＄0. 17 billion and it will be ＄0. 3 billion this year. The imported membrane is about 70 % sales in China. The output of locch ＄1. 6 billion in 2001 with the annual growth rate of 8. 0 %. In 1997 , the sales of membrane

product s for water treatment was ＄0. 97 billion in Europe. It is reckoned to be ＄1. 65 billion in 2004 with the annual growth rate of 7. 9 %. According to these growth rates , China will catch up with USA and Europe in the coming years as shown in Fig. 1.

Tab. 1 Chinese membrane companies with the output of over ＄1. 2 million

Fig. 1 The output increases of membrane products in USA , Europe and China

There are tens of research institutes in China , of which more than 20 are on UF and MF membrane. Meanwhile , there are two research bases on membrane. One is the aqueous membrane research institute — The Development Center of Water Treatment Technology , SOA Hangzhou China , and the other is the gas membrane research base —National Engineering Research Center of Membrane Technology ,Dalian , China.

4 Application of membrane in water treatment

The application of membrane in water treatment depends on it s effectiveness of separation and cost of process. As an advanced separation technology , it is endowed with many advantages : high selectivity , applicability under ambient temperature without phase change , low cost of energy , high level of automation ,low pollution and etc.

4. 1 Desalination of seawater and black water

RO is the most economical way for the desalination of seawater and black water. The energy consumption is less than 5 kW·h/ t for seawater or 0. 5～3 kW·h/ t for black water. The biggest plant of RO for seawater desalination can produce water 2. 1 ×105m3/ d , for black water is 1. 3 ×105 m3/ d. It seems that RO is the best method to solve the problem of drinking water and industrial water in the draught areas. It can be verified by the fact that most of the largest desalination plant s are located in Middle East as shown in tab. 2[3 ]

4. 2 Purification of drinking water

Membrane is the best tool for the purification of drinking water because it can remove the suspended substance , bacteria , toxic metallic components and organic components to improve the water quality. 90 % of the city water is productive water, only 9 % supplied water is the domestic water and only 1 % is drinking water. To supply water separately for the resident zones is an effective way to improve the quality of drinking water. Supplying water separately is to treat the 1 % supplied water with membrane for special purpose. Separate supply system has been built in some resident zones of Beijing and Shenyang , which mainly use RO membrane.

4. 3 Reuse of municipal domestic sewage

City sewage is an important potential water resource. Recycled water for different purposes can be produced from the domestic sewage with membrane. It is an effective way to solve the shortage of water resource.

There are 3 domestic sewage treatment factories in Beijing , and another 4 are under const ruction. In addition , 15 more are to be built . The sewage treat ratio will mount to 80 % in 2006. Two million tons of the treated water will flow out from these wastewater treatment factories. After treated with membrane , the water can be reused for industrial purpose , green area and other fields. In this way , the municipal supplied water can be reduced , and the water resource can be fully utilized. If the membrane technology is applied in the deep treatment of the city sewage ,more than one million tons of discharged wastewater will be reduced every day only in Beijing. At the same time , more than one million tons of the water resource can be saved. So it would retrench 0. 36 billion tons of water per year. This method can reduce the water pollution , as well preserve the water resource.

4. 4 Treatment of industrial wastewater

Industrial wastewater has many types in large quantity and it is very harmful. If the wastewater can be treated , it would not only preserve the resource ,but also protect the environment because the wastewater contains some deleterious substances such as oil ,metallic ions , phenol and etc. The membrane technology bears splendid significance in the industrial wastewater treatment . In early 1970s , RO membrane began to make the electric plating wastewater recycled ; Charged UF membrane turned the electro coating system in automatic company into clean producing line. The wastewater treatment with membrane recycled the wastewater in dyeing process ; UF membrane is a key technology for the reuse of oil wastewater.

5 Future of membrane application in water treatment

The essence of membrane technology is a highly effective material. The material should provide high flux , high selectivity and so on. In the wastewater treatment , we often encounter hazardous condition. Under such kind of circumstances , organic membrane sometimes cannot meet the requirement . Consequently , more attention is paid to the inorganic membrane now that has fulfilled a considerable progress in these years with a rate of 30 %. Currently China can produce tube ceramic membrane on industrial scale. With the decrease of water resource and the increase of water pollution , it is definitely that the membrane technology , the separation technology of the lowest energy cost , will realize a brilliant future. RO , NF ,UF , MF , ion - exchange , dialysis etc which are mainly used in water treatment will be the center of membrane technology. China is a country with a large population of nearly 1. 3 billion people , which covers one fifth of the world population , but the water resource is only 1/ 20 of world. Therefore the water resource per capita is only 1/ 4 of that of the world. Membrane is an effective means to solve water problem. The advantage of membrane in water treatment is more and more obvious while it s application is wider and wider. The membrane industry of China marches rapidly at a rate of 30 % annually. However , the difference from the developed count ry is still big. The membrane output per capita is merely 1/ 32 of that of USA and 1/ 12 of that of the world. The membrane market in China is huge with a bright outlook. To enhance the application of membrane in

water treatment , we should :

膜技术和环境保护中的水处理

摘 要： 这篇文章简单介绍了目前中国水资源和膜工业的现状。目前，世界水污染日益严重，水资源日益短缺。中国有660 个城市，360 个城市缺水，110 个城市严重缺水，40 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46. 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。膜技术是一种可以用来提高人们饮用水质量、处理污水节约水资源的清洁技术。中国也有众多的膜研究人员和膜公司。这篇文章介绍了中国膜技术的研究和膜制造的一些数据。 关键字: 膜技术;水处理;s环境保护

1 简介

水是对人类最为重要的资源，水资源的各种问题也比以往严重的多。

中国是经济飞速发展的发展中国家。但是随着经济的发展生态环境问题也日益严峻，例如资源短缺、生态破坏、环境污染等等，这一切对我们的生存水平的提高和经济的快速发展都有极大的束缚。现在政府致力的西部大开发，经济发展和环境保护同为重中之重。

膜分离技术是一项新型技术，在被开发至今的几十年中发展非常快。1952年，Reid第一次介绍了用反渗透技术淡化海水想的设想。1960年，Loeb和Sourirajin生产了第一个有实际应用可能的反渗透膜，这标志着膜科学与技术的诞生。中国对膜技术的研究和发展有40年的历史。其中反渗透、纳滤、超滤、微滤、电渗析、渗透汽化膜、液态膜、膜反应器等都有一定发展，并且在能源、电子、石油、石化、制药、重工业、轻工业、食品、酿酒业以及人们的日常生活、环境保护等领域都投入了使用。特别是在水处理方面，膜技术的应用面越来越广，发挥的作用越来越重要。

2 中国水资源和水污染的现状

在众多的环境问题中，水的问题是最为严峻的。全球三分之一的人们都面临着水资源短缺或者废水处理的问题，而这个数字在未来30年内将会翻倍。有专家预测，水将代替石油成为区域冲突乃至全球冲突的主要原因。

中国有660个城市，其中360多个城市缺水，110个处于紧缺状态，更有40个城市位列极度缺水的城市名单之中。据估算，中国每年的缺水量为400.00亿吨，到2030年，这个数字将会上升到600.00亿吨，而由于水资源的短缺，产品产值每年将会减少2400亿元人民币。

在过去数年中，中国水资源的水质不断恶化，被污染的河长逐年提高。据1999年统计数据，在监测的100万公里的河流中，46.5％受到污染，但废水处理率只有23％。

水污染已成为经济发展和社会进步的障碍。在长江三峡库区，21个县区的废水排入长江，导致水面上升2~4米，有时甚至可以达到6.5米，这直接影响了葛洲坝水电站的工作，也导致了二江水电站的频繁故障。这种浮动造成的损失最为严重的一次是约为14 000kW的电力损失，约等于一座小型发电站的发电量。

水污染不仅是经济发展的障碍，也已经危机人们的生存。由于被污染，yangteng湖的水质从2级降至3级，不不能用作饮用水水源。

3 我国膜工业的发展

中国有许多关于膜技术研究机构和研究人员。关于电渗析和离子选择交换膜的研究始于1958年[2 ]，反渗透膜1965年，超滤膜的研究则始于20世纪70年代。20世纪80年代，在制造出双中空纤维超滤膜后，最早完成的超滤膜——醋酸纤维超滤膜被用于电气系统。关于纳滤膜、汽化膜，无机膜、渗透汽化膜和液态膜等的研究也有很大发展

虽然中国膜技术行业并不十分壮大，但其发展速度却非常之快。根据1997年的统计数据，中国有13家大型膜生产公司的总产值超过1 200万美元（表1）。膜单项出口量是四千五百万美元，其中进口价值两千七百万美元。膜相关工业出口量估计为1.7亿美元，而且今年将达到3亿美元。百分之七十的进口膜在中国内陆销售。国产膜出口量以每年百分之三十的速度增长。

1997年，全球关于膜技术及其相关设备的总产值约为100亿美元，据估计，到2000年将上升至140亿美元。1997美国膜工业的产值为11亿美元，到2001年，这一数字将会以8.0%的年增长率上升至16亿美元。1997年，欧洲有关于水处理的膜产品的销售值为9.7亿美元，据估计到2004年将会增长至16.5亿美元，年增长率为7.9%。如图1所示，根据以上增长速度，中国将在未来几年中赶上美国和欧洲。

中国有数十家关于膜技术的研究机构，其中有20多家致力于超滤膜和微滤膜的研究。同时，我们还有两个膜技术研究基地，一个是水膜研究学院——中国杭州SOA水处理技术开发中心，另一个是气膜研究基地——中国大连膜技术国家工程研究中心。

4 膜技术在水处理中的应用

膜技术在水处理中的应用决定于其分离效率和过程成本。作为一种先进的分离技术，拥有许多的优点：高选择性，适用环境温度下无相变，能耗低，自动化程度高，低污染等。

4. 1 海水淡化和处理含细菌腐蚀产物的水

反渗透膜是淡化海水和处理含细菌腐蚀产物的水最为经济的方法，淡化海水的能源消耗小于5 kW·h/ t，处理含细菌腐蚀产物的水的能源消耗为0. 5～3 kW·h/ t。最大的应用反渗透膜急性水处理的公司每天的淡化海水量为2.1×105m3/ d，处理含细菌腐蚀产物的水量为1.3×105 m3/ d。反渗透似乎是解决干旱地区饮用水和工业用水在这个问题最好的方法。这是已经验证的事实，大多数最大坐落在中东的海水淡化工厂都可以达到这个标准，具体数据参照表2。[3 ]

4. 2 净化饮用水

膜是净化饮用水最佳的工具，因为它能去除悬浮物质、细菌、有毒金属成分和有机成分，提高水的质量。90％的城市用水是生产用水，只有9％的供水是生活用水，只有1％的是饮用水。对居民区用水进行区分供应是提高居民饮用水质量的有效途径。区分供水是用利用膜技术对这1%的饮用水进行特殊处理，单独供应。这种居民用水分别供应的系统已经应用在北京和沈阳的一些居民区，主要应用的是反渗透膜。

4. 3 市政污水的回用

城市污水是一种重要的潜在的水资源。用膜把各种不同的回收水进行处理，用作生活用水。这是一种解决水资源短缺的有效方法。

北京有已建的3座、4座正在建造中生活污水处理工厂，而将要建设的有15座。到2006年，污水处理的比例会提高到80%。这些废水处理工厂的处理量将达到2亿吨。水经过膜处理后，可以达到重复使用的目的，如用作工业用水、绿化用水以及其他的领域。以这种方式，市政用水供应量可以降低，而水资源也能够得到充分的利用。如果膜技术应用在城市污水深度处理，仅在北京每天就将减少超过100万吨的污水排放，同时，也就节约了超过100万吨的水资源。这样每年就可以每年减少3.6亿吨水的水费开支。这种方法能减轻水污染，保护水资源。

4. 4 处理工业废水

工业废水中有大量的各种类型的物质，是非常有害的。如果对废水进行处理，它不仅能保护

There are 660 cities in China. Among them , more than 360 are short of water and 110 are in urgent situation. Further more , 40 cities are in the list of the cities that are ext remely short of water. It is estimated that the water shortage will be 40 billion tons annually , and that China will lack 60 billion tons water in 2030. Due to the water shortage , the product output decreases by 240 billion RMB yuan annually.

The water quality in China was deteriorated over the past few years. The polluted river length increased every year. According to the statistical data in 1999 , 46. 5 % of

rivers were polluted in 100 000 km monitored rivers , but the wastewater treated ratio was only 23 %. [1 ]

Water pollution has become the obstacle of economic development and social progress. In Sanxia reservoir of Yangzi River , there are 21 counties discharging wastes into Yangzi River.

The worst case happened was that once a time the float caused severe power plants breakdown with an electricity loss of 14 000 kW , equal to the capacity of a small power station.

Water pollution not only becomes an impediment of the economic development , but also endangers the existence of the people. The water quality in Yangteng Lake drops to grade 3 from grade 2 , which causes the water undrinkable.

3 State of membrane industry

China has a lot of research unit s and researchers on membrane. The research on electric dialysis and ion exchange membrane began in 1958[2 ] . RO membrane began in 1965 and UF membrane in 1970s.The earliest prepared UF membrane , cellulose acetate UF membrane , was used in electric coat system in 1980s , after polysulfone hollow fiber UF membrane was manufactured. The researches and the development also went ahead rapidly on NF membrane , gas membrane , inorganic membrane , pervaporation membrane and liquid membrane.

Although the membrane industry of China is not big , it grows up very quickly. According to the statistical data in 1997 , there were 13 big companies of membrane with the output over ＄1. 2 million in China ( Tab. 1) . The output of solo membrane was ＄45 million , within which the imported value was ＄27 million. The industrial output relevant to membrane was estimated ＄0. 17 billion and it will be ＄0. 3 billion this year. The imported membrane is about 70 % sales in China. The output of locally manufactured membrane increased by 30 % annually.

In 1997 , the global output value of membrane and it s relevant equipment was about

＄10 billion. It is estimated that the output value will be increased to ＄14 billion in 2000. The output of membrane industry of USA was ＄1. 1 billion in 1997 and will reach ＄1. 6 billion in 2001 with the annual growth rate of 8. 0 %. In 1997 , the sales of membrane product s for water treatment was ＄0. 97 billion in Europe. It is reckoned to be ＄1. 65 billion in 2004 with the annual growth rate of 7. 9 %. According to these growth rates , China will catch up with USA and Europe in the coming years as shown in Fig. 1.
