Our scientists achieved important breakthrough in the field of solar desalination

Along with the social development, water resources become increasingly scarce, shortage of water resource is becoming a global need to confront the challenge. Hot steam technology in solar energy and water as raw materials, to production provides a path of clean water. However, the traditional block heat, steam technology due to the low water production efficiency ( About 40%) To meet the actual demand.

in & other; Nanotechnology & throughout; Focus on special & other; Surface from the excimer efficient solar-thermal conversion mechanism, such devices and solar heat utilization & throughout; Project, supported by nanjing university professor Zhu Jia team will porous alumina templates with metal nanoparticles self-assembly technology, innovative design of a new type absorber material, in 400 - nm to 10 & mu; M band has 99% of the sunlight absorption efficiency. Combined with a new design of the interface thermal conversion apply this material to seawater desalination, hot steam conversion efficiency can reach 90%, and the water quality can meet the WHO's drinking water standards.

on this basis, the team further hydroelectric power plant using steam enthalpy storage and solar energy, rely on the sun and natural water two kinds of the earth's most abundant resources, clean water and electricity power plant can be realized. At the same time, the team will also interface solar steam technology innovation to promote the wastewater treatment, sterilization and other fields, have achieved good results.

the scientists achievements in our country, caused the extensive concern of international academia and industry. Science to the new water purification system can help the world thirst 'topic of panel is introduced. A new solar desalination technology shows a broad prospect, not only can provide economic and feasible for poor, remote areas of drinking water, can also be used for military special areas such as ocean, desert, small, portable water supply scheme and application field, are more likely to contribute to global water shortage problem & other; China water solution & throughout; 。
