On March 24, 2008, appear for the people that this day uses to paying close attention to Chinese water natural resources very not common. This day, our country is the biggest " double membrane method " 35000 tons / project of day seawater desalination is in China China can power plant of group jade annulus moves successfully two years, this means our country to master the experience of design of engineering of large seawater desalination, construction and operation already completely. This to from go up at all solve the import of problem of bottleneck of water natural resources that restricts our country coastal economy to be able to develop continuously great.
Want water to the sea
Shortage of water natural resources has become one of important bottleneck that restrict economy of our country foreland to be able to develop continuously. Power plant of Hua Nengyu annulus " want water to the sea " , solved an enterprise not only total production, life uses water, still be in low water is seasonal, contented county inmate uses the 1/3 of water.
According to data of national statistic bureau, our country is coastal 11 provinces, city, area with the whole nation the land of 15% , supported the throughout the country the population of 40% , created the whole nation the gross domestic product of 67% . Is foreland right of Chinese economy tremendous urge action whether continue to be developed?
Important restricting an element is water -- the 1/4 that gross of foreland water natural resources takes the throughout the country only. Capacity of natural resources of water of our country average per capita is 2700 tons, and 4 province city of northward and coastal Tianjin, Heibei, Liaoning and Shandong, operable water measures put together of average per capita to be 269 tons only; Southern and coastal integrated water consumption is average per capita of 7 provinces city 560 tons, all be in the extreme position that lack water. Many areas exceed as a result of groundwater collect, had caused the ground to sink, seawater flows backward, zoology environment is exasperate.
Power plant of Hua Nengyu annulus is located in Zhejiang to visit jade annulus island on the west side. Here does not have the requirement that proposes large reservoir, fresh water resource is very nervous. Average per capita of jade annulus county has water natural resources 656 tons, far save 2400 tons under Zhejiang, the whole nation level of 2700 tons average per capita. According to bureau of prefectural irrigation works Qian Yunfei of former deputy director general introduces: "Since 2002, jade annulus county encounters big drought of in successive years, 3 talents offer inmate of county of low water season water, water supply time only 2, 3 hours.
