Recently, a friend forwarded on a sea water desalination in the news Micro message, caused the friend inside the circle is a warm discussion.
The news said: from June 11th is being held in the 2014 Qingdao international desalination conference learned, China desalination using volume from 8000000 cubic meters in 2005, increased to 110000000 cubic meters in 2012. The experts, the current domestic desalination costs per ton of about 3.7 yuan, the sales price is about 5 yuan, but some people do not want to use the desalinated seawater to wash the dishes, wash the dishes, the public idea restricts further development of Chinese seawater desalination.
The author said that the current domestic desalination costs per ton of about 3.7 yuan, the sales price is 5 yuan about information be puzzled of message. For more than a decade ago, the relevant units of the state had to desalinate seawater expectation price for 5 yuan per ton, and said with tilting technology progress and national policy, desalination will present promising prospect. Eight or nine years ago, the author in the message mentioned Qingdao international desalination conference, experts from the report to see the sea water desalination prices unexpectedly and message in digital striking similarity. I wonder, is it 10 years of desalination technology in China no progress, so that the price does not have any change? It is the price of electricity and water prices rose sharply over the past 10 years, has no influence on the desalination of sea water price? I really don't want to believe that this is the palace of the experts on the literature become an author, lifelong results with a paper, but perhaps this is the reality of the existence of. Because a friend told the author, Liaoning Changhai seawater desalination more than 7 yuan a ton.
China is one of the 13 countries in the world the most depleted water, development and utilization of non conventional water resources is an important way to solve the shortage of water resources, and vigorously developing seawater desalination is a promising weight
To move. Some experts put the control Chinese desalination crux of the further development of arbitrarily attributed to public opinion, a beg to differ. Even with the logic of the news, from the price analysis, also said impassability. Now the water price geometry, desalination is how many? Can't you just high forcing people 舍廉, with convenient water not to use desalination? In Saudi Arabia, all the fresh water from the desalination of sea water, tap water can be directly consumed, each household a month of water only 1 rials (about 1.7 yuan), this does not give us some inspiration?
This circle of friends finally concentrated to a question, is restricting the further development of seawater desalination China crux in where? For such problems, the answer is of course each according to his lights.
I think there are 3: one is the shortage of fresh water crisis consciousness is weak. People leave the water will not be able to survive, the simple common sense knows. But in many people's minds, always think that is very far away from us, and had nothing to do. So they stick to traditional values, there is no sense of crisis and sense of urgency. This phenomenon not only in ordinary people, even among policymakers also There are plenty of people who.
The two is the current technology is still not enough to produce enough high quality of desalinated water. On this argument, maybe some experts are not willing to listen to, but we should be clear, we engage in seawater desalination, not to be published several papers, as several reports, but rather to produce people recognized, accepted products. Goods is only accepted by the market is full of vitality, it is not only the problem of consumption concept.
The three is the policy guidance, support is not enough. If consciousness to the crisis, if we recognize the seawater desalination is an important way to solve the water crisis, countries should strengthen policy guidance and financial support to promote the desalination industry, speed up technological progress, the formation of scale as early as possible. At the same time the price guide, form the market. Since we can spend a lot of money to do a matter of expediency of water, so why don't more strength in the field of sustainable? |
