The Study On The Availability Of The Reuse Of Reclaimed Water In Quanzhou City

Quanzhou is one of the China's rapid economic development cities and the representation of municipal services have been expanding in the southeast coast of medium-sized city. With the city's reform and opening up, the rapid development of industrial economic, the rapid expansion of the urban population and the corresponding increase in urban water consumption, industrial wastewater and domestic sewage emissions have multiplied. The shortage of water resources and the sea water quality deterioration in Quanzhou city caused by water pollution has become an important social and economic sustainable development constraints. Reusing reclaimed water not only can reduce the quality of water resources consumption, but also reduce the pollutants discharged into the water. That is of great significance of the sustainable use of water resources in cities. How the regional level in urban regeneration in all directions to establish water cycle system, objectively evaluate of the use of renewable water level, mate the strategy of reclaimed water reuse is to be resolved on the current hot spots. This paper did some study on the feasibility study of reclaimed water reuse in Quanzhou.This paper did some researched and summaried on the Research and Application of wastewater reuse projects at home and abored. Systematically analyzed the status of economic and social development characteristics and trends of Quanzhou City. Objectively evaluate the city's use of water resources status, water supply, water comsumption, sewage treatment status and trends. After analysing the causes and the solutions to urban water shortage, summarized the necessary of implementation of reclaimed water reuse project. Surveyed the market of reclaimed water and Forecasted the demandthe. Pointed out there is great potential for reuse in the green, car washing, watering roads, irrigation, resurrect Intra-city river in terms of recliamed water in Quanzhou City.According to the conditions of sewage water plant and the surrounding region of the municipal water distribution, proposed to Bao Chau Sewage Treatment Plant as the center of the reclaimed water supply system and the vision set by comparing the scale of the water supply. Finally, this paper analysed the efficiency of reclaimed water reuse in Quanzhou in the economic and social benefits by the quantitative and qualitative method, presented proposals to the problems of the implemention of reclaimed water reuse project.The results show that it is necessary to reuse reclaimed water in municipal, it is feasible in technical and economic to implement sewage water recycling project in Quanzhou.The results of research on this paper will provide reference for decision-making to other small and medium-sized Southeastern coastal cities.
