Title: Water Structure & Water Quality/ Quantity Management
Abstract: 
“What is the structure of water ?”is the 46th issue among the 125 issues summarized by <SCIENCE> in 2005 as the most challenging issues in frontier basic sciences. The models for water (H2O) molecule, liquid and solid states including snow and liquid water skin have been developed by authors of this paper. The water molecule is an equilateral triangular pyramid with 2 pairs of “+/-” electricity endpoints and edge length of 0.48017nm. The water ice structure has porosity of ≥2.28. The liquid water has the same structure of the solid ice, but there are 1/11 molecules leave from frame and get into the frame, being a “free water”; so the specific gravity of ice is 11/12. The conductivity of pure water is very low. The liquid water skin has 2 layers of special structure with porosity of 1. There are 1/1115 evaporated molecules from water surface may be negative ion. The thunder and lightning transfer the negative electricity return to earth surface like rainfall transfer the evaporated water molecule return to the earth surface. There are Zigzag Hexagon Tunnel-Vacancy Systems, where may store various substances, as “pollutants” (some of them are life supporting substances; the TDS and conductivity of polluted water increased with pollution state). The water has recycling characteristics in quality/ quantity and gas/ liquid/ solid state. We may remediate healthy aqua-ecosystem by high technology of Physic- Ecological ENgineering-PEEN using mainly solar energy, transforming pollutants into usable resources. In spacecraft we may recycle water quantity/ quality by using solar energy. The soft filter-wall-enclosures with sufficient vertical width for adapting variation of water level and wave-current are specially made up (like parachute) by synthetic fiber with floating up bar and lower anchored bar and might be easily assembled and anchored and adapting water level change and wave concussion at site for separating and filtering waters . All these construction in the catchment would be propitious to water level stable and decrease the possibility of drought and flood disasters. Various types of floating/ suspending eco-islands for cultivating plants, including vegetable, feedstuff, flower, and snail, mussel, mollusk,. etc. Technology of Immobilized Nitrogen Cycling Bacteria-INCB, including 4 type bacteria and their carrier may accelerate decreasing nitrogen and COD in waters. “Jellyfish Engineering” may be used for collecting algae bloom by wind and transforming it into usable resources. Technology about planting, collecting, managing, and immediately drying water-hyacinth may be complexly used. Electric pulse+ photosensitization technology for decomposition of difficult decomposition chemicals using DC 24V and technology for quickly suppressing H2S and increasing O2 have been developed. We may develop water body ecological agriculture. By using dried water-hyacinth + wastewater+ vetiver grass+ management we may construct grass forest (much more quickly than tree forest) for suppressing sand blown by wind. System of DC 24V net may control fog and haze. Underground channel reservoir without take off soil may decrease drought and flood disasters. Planting vetiver grass may use for decreasing water and soil loss and insect disease prevention.
