Research On Using And Marketization Of Recycled Water In Tianjin Binhai District

Water is the basis for the human survival and development.But with the development of economic and the improvement of people's living standard, the shortage of water has become a key factor constrained urban development. Tianjin is a typical city of water shortage in China. The average water resource per capita is only 160 cubic meters, which is far below the recognised shortage of water (1000 cubic metres) in world. Tianjin Binhai Area with a lower average water resource per capita faced severe water shortage. Tianjin Binhai Area locates in the east coast, where there are a large number of wasteland and shore. The area is recognized the ideal regional for development of modern industry because there is rich of oil, natural gas, crude salt, marine resource and so on. However, the shortage of water has resulted in wetland shrinkaged significantly and surface subsidence; it affected the economic development and people's living standard seriously. In order to solve these above problems and build eco-friendly area, developing recycled water is the realistic choice for Binhai Area.This paper introduced the present situation of water shortage in Binhai Area, then it analysed the water supply and demand conditions in Binhai with market supply and demand theories. The author expounded and proved the necessity and feasibility of using recycled water, analyzed the reason why producers and consumer with low enthusiasm in recycled water.Secondly, the paper presented achieving recycled water marketization, establishing a comprehensive market competition system to provide fair environment for competition, broadening the financing channels, thereby resolving issues such as insufficient investment in recycled water. The author also analyzed the trengths and weaknesses in marketization in Binhai with the swot model. In addition, price is one of the important factors to achieve marketization, and it is also the main factors in affecting supply and demand.This paper select the cost-price model from the perspective of market equilibrium, and calculated the recycled water price of Binhai Area.Finally, promoting recycled water need the support and encouragement from local government. The government should enacte classe on economic, technological and other aspects to incentive the producers and consumers, increase supply and demand of recycled water, raise the utilization rate of recycled water.
