| Water treatment by membrane separation" membrane" force" Twelfth Five-Year Plan" | | News source: Reads:6211 AddTime:2011-4-16 11:51:00 Collects this page |
| Chinese Academy for environmental planning after a forecast, our "Twelfth Five-Year Plan" and" 45" period wastewater management investment will be amounted to respectively 1.05 yuan and 1.39 yuan, among them industrial and urban sewage treatment investment will be amounted to respectively 435500000000 yuan and 459000000000 yuan. Think inside course of study, in the policy background, separating film industry will usher in the" ten years", the strategic opportunity to highlight.

China’s water resources are becoming scarce and industrialization still is in rapid development, how to alleviate resource and the development of this pair of contradiction in China has become the " 12th Five-Year Plan" to face a big problem. As a solution to one of the paths in the chlor-alkali industry, water treatment, and other fields have a wide range of application to the separation of the membrane will play a key role.
A reporter from the China Film Industry Association vice president and Secretary General Eugene de was informed, the association is responsible for the preparation of the" separation" Twelfth Five-Year "plan" (hereinafter referred to as" planning" ) a few days ago already formulate ends and reported to the Ministry of industry and information technology, development and Reform Commission, Ministry of science and technology and other relevant state ministries and commissions, the future may be listed as" high performance membrane material" 925 "special program". According to the plan, China during "the Twelfth Five Year Plan" period will massively increase separation membrane separation membrane self-sufficient rate, in whole area form a complete large-scale production capacity and realize the import substitution, related varieties production also will grow considerably.
Planning the main drafter -- China Membrane Industry Association of engineering and application of professional committee chairman Chen Guanwen researcher told reporters, the plan is expected to be incorporated into the Ministry of" new materials" Twelfth Five-Year Plan " and the" Ministry of science and technology" high-tech" Five-Year " planning", on the separation membrane industry over the next 5 years great progress will be play an important role in supporting and guiding.
Ultrafiltration and microfiltration membranes: water treatment "magic wand"
As at the end of the twentieth Century was the emergence of a water treatment technology, membrane separation technology in the industry is not well known, the current industry on a small scale. But the" 12th Five-Year Plan", China for water treatment will enter into a new stage, in the field of water play a decisive role separation membrane technology also is expected to usher in rapid growth.
" This year the No. 1 document of the Central Committee to water safety as the primary event, and realize the safety of drinking water treatment, proved" membrane" can not be." Eugene de.
According to the" membrane" Twelfth Five-Year Plan " Chinese", in the "12th Five-Year Plan" will massively increase separation membrane separation membrane self-sufficient rate, in whole area form a complete large-scale production capacity and realize the import substitution, which relates to a water treatment ultrafiltration and microfiltration membrane annual production capacity will reach 45000000 ~ 50000000 square meters; electric drive film formation of 1000000 to 1300000 square meters of annual production capacity of.
" China has 300000000 people not to drink water, but 2012 will implement new standard of drinking water in most places are not, it depends on the membrane method treating to target." Chen Guanwen said.
Reportedly, the late on July 1, 2012 mandatory implementation of the" drinking water health standards" ( GB5749-2006 ) will be drinking indicators from the original standard of 35 to 106, and the original standard of 35 indicators in the 8 revised. According to this standard, with the membrane for advanced treatment of drinking water is the only way which must be passed.
Originally the industry" to film, because the film is too expensive, but now is different, the membrane method treating water plant at home more and more recognition and promotion of city." Chen Guanwen said.
From" eleven five" at the end of the beginning, with the membrane method treating city water works have been started. Hangzhou, Wuxi, Dongying, Beijing, the construction of membrane water treatment in water plant. Among them, Beijing at the end of last year the planning of the 500000 tons / day water plant has passed the certification, known as the world’s largest scale.
" You can imagine that, if an annual processing 500000 tons of water using membrane process, will require much film? China also has many such plant need to transform? This is a quite big market." Chen Guanwen said.
The planning also mentioned," Twelfth Five-Year Plan" will build the processing scale of 500000 - 750000 cubic meters / day of water membrane purification engineering. " Not only that, in sewage treatment, industrial water recycling, separation membranes also play." According to Chen Guanwen, the future of the country may have on some new large items not for water use index, and asks the enterprise must use municipal wastewater, which requires the adoption of the membrane method treating the wastewater into recycled water.
Eugene de said, at present on international areas of wastewater reuse of membrane engineering has accounted for more than 95% of the total, China also has 90% above the membrane material for water treatment.
Eugene de pointed out that, as early as in 2010 Shanghai World Expo, the membrane as the core of direct drinking water system for Expo seventy million viewers with a healthy drinking water, the main health indicators even better than the EU standards. Therefore, if the" separation membrane industry" Twelfth Five-Year Plan "" come true as scheduled, the drinking water quality will have a qualitative leap.
Reverse osmosis membrane: seawater desalination" killer mace"
" In addition, seawater desalination and membrane separation is an important application field. After an internal meeting, the leadership has said, China in seawater desalination will launch a campaign." Chen Guanwen said.
" Realizing desalination methods including distillation, membrane method, ion exchange method etc.. The membrane technology because of high efficiency, no phase change, less energy consumption, low operation cost has become the preferred technology for seawater desalination." Eugene de.
National hair changes appoint annulus endowment department water saving Commissioner Yang Shangbao said, according to incomplete statistics, at present, our country has built desalination engineering capacity reached 600000 tons / day, 60% of them by membrane technology. Related" Twelfth Five-Year Plan" proposed desalination capacity will reach 2200000 - 2600000 tons / day, implies that the membrane technique with more display space.
" Expected" 12th Five-Year Plan " will also designed and built 200000 - 300000 cubic meters / day of reverse osmosis seawater desalination system, a new seawater desalination capacity of 1000000 - 1500000 cubic meters / day. Along with the sea water desalination project scale and maturity, using the membrane for seawater desalination project is expected to further increase the proportion of." Eugene de.
As for drinking water treatment also requires the use of reverse osmosis membrane", such as the current widespread use of bottled water, mostly through the reverse osmosis membrane filter." Chen Guanwen said. " The present domestic reverse osmosis membrane market share only 10%. We hope that in the future this one proportion will rise further, and even increased to more than 50%." Eugene de.
According to the plan," 925" during the reverse osmosis membrane annual production capacity to reach 10000000 square meters, domestic reverse osmosis membrane share will rise to 25%-30%. But at present, the domestic reverse osmosis membrane annual production capacity of 4000000 square metre only.
Ion-exchange membrane chlor-alkali industry:" golden touch"
" In addition to water treatment, membrane separation and various other applications, including recovering useful substances, gas separation and dialysis etc.." Chen Guanwen said. Among these, perfluorinated ion exchange membrane as the membrane of a, in chlor-alkali chemical industry, new energy field of great application value.
The reporter understands, our country existing chlor-alkali industry device size of more than 38000000 tons, is the world’s first production big country. But the domestic industrialization of ionic membrane caustic soda in China before, ion by ion membrane core material 100% dependence on imports, become industry of our country base of chlor - alkali industry safety operation and healthy development bottleneck.
In order to eliminate the threat to national economic security hidden trouble, begin from 1980, our country will this technology included in the national" six five"," seven five" key science and technology program, has invested hundreds of millions of yuan of funds for scientific research, but there has been no successful development.
Until September 22, 2009, Dongyue Group developed for chlor-alkali industry large area of perfluorinated ion-exchange | | Total:2 pages page: 12 |  |
