Research On Xi'an Reused Water Using And Pricing

Urban reused water using means that wastewater can be treated to a sort of steady water resource and reused in irrigation, industrial cooling, municipal virescence, road insufflations, groundwater replenishment, surface water supplement and other aspects. This sort of water resource is called reused water. Wastewater reuse can resolve the crisis of water resource shortage effectively, and protect nature environment as well. However, currently in the process of wastewater resource utilization in China, it is lack of scientific basis and practical methods in reused water pricing, The pricing problem of reused water has become a crucial and central problem.China's water prices and water charges are obviously at the low level, and the reused water supply relatively cost high, It is very difficult to give a reasonable price of reused water. The reality is either reused water at high prices, resulting the lack of market demand, the amount of reused water often not achieve the design size; or it is at low prices, resulting in the production of reused water cost recovery it is difficult for enterprises and investment. This has seriously hampered China's sewage resources of the development of the cause.This paper mainly urban reused water pricing theory and method, the value and price of reused water theory, pricing, price mechanism for the implementation of all aspects of a comprehensive study of the economic cycle and conservation-oriented social theory, the theoretical value of reused water and reused water resources price model integration theory, and Xi'an is given as an example of reused water at reasonable prices.Xi'an cited by the current status of water resources and the use of reused water, and reclaimed water reuse come in the necessity and feasibility of Xi'an, as well as the problems that exist. Analysis of the status quo in Xi'an reused water prices, taking into account the elements of reused water prices, changes in the interval and pricing factors in the comparison of the reused water resources shadow price, the marginal opportunity costs, fuzzy math, such as the cost model, the feasibility of using the average cost model to estimate the price of reused water in Xi'an, given Xi'an reused water at reasonable prices and the price difference between different users, illustrated by the two sides for earnings.Apart from the price of reclaimed water, sewage impact of the development of the cause of the resources and some other factors, in view of these factors, the paper also made a number of encouraging policy, many of methods to jointly promote the development of the sewage resources reuse.
