The Research Of Trend Of Industrial Water And Water Saving Measures In Wuhan City

As the city economy society enters a rapid development track, Wuhan isfacing increasing pressure from resources and environment. The issue of waterresources has become an important factor which restricts economic and socialdevelopment. Analysis shows that industrial water occupies a large proportion in thewater of the whole Wuhan city. Industrial water saving, optimal allocation andefficient utilization of water resources is a significant way for rational and efficient useof water resources of Wuhan to ensure its sustainable development. Therefore, itconveys real social benefit and economic benefit to analyze the development trendof industrial water consumption and water saving potential in Wuhan city, thusproviding support and basis for the sustainable development of industrial water inWuhan City.This thesis analyzes the influencing factors of Wuhan industrial water and makes medium and long term prediction of Wuhan City industrial water by regression analysis and systemic dynamic method. Two reciprocal validation results show that high reliability. Through construction of industrial water saving evaluation indexof Wuhan city and determining the index weight by analytic hierarchy process todetermine, this thesis adopts comprehensive index to calculate the industrial waterconservation index of Wuhan City over the years.The results of the study show that industrial water saving level of Wuhan keeps gradual improvement in the past ten years, but still falls respectively far behind that of developed city and regions in domestic and foreign areas. If it develops with current situation, the industrial water will surpass5.78%and18.69%. of the water use red line designated by China respectively in2020and2030. Basedon the red line of industrial water, this thesis proposes the industrial water conservation target that water consumption for each ten thousand yuan of industrial output value will decrease to12.19m3/ten thousand yuan and8.38m3/ten thousand yuan respectively in2020and2030in Wuhan, industrial water consumption of each ten thousand yuan added value will decrease to30.47m3/ten thousand yuan and20.95m3/ten thousand yuan, recycling rates of industrial water will respectively increase to89.99%and the91.68%.This thesis also puts forward corresponding countermeasures of industrial water saving aimed at the water saving target.
