The Research On Reclaimed Water Programming Optimization Model Of Weifang

Water is not only one of the most valuable life and production resourses of the humanbeing's,but also one of the strategic resourse of the country's.China is poor in water and it is a constraint to economic development.What's more,Weifang is a serious water shortage city. With the rapid economic development, water is the key of economy and society development.Reuse of wastewater is one of the most effective and possible measures to solve the problem. The wastewater of Weifang is enormous and is creasing in recent years.It will ease the water shortage problem of Weifang if we make full use of recycled water.In fact, the usage of reclaimed water has been seriously considered for the above reasons. It proved that there is not difficult in technical process. However, there is much to do about reclaimed water planning and programming.So, it is more and more urgent for us to do reserch in reclaimed water planning through which we could provide suggestions for the government.This paper did some researched and summaried on the research and application of wastewater reuse projects at home and aborad.Systematically analyzed the status of economic and social development characteristics and trends of Weifang.Objectively evaluate the city's use of water resources status, 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 projects and surveyed the market of reclaimed water and forecasted the demand.Pointed out there is great potential for reuse in Weifang.Second,applying the system engineering and mathematical programming, this paper made a detailed research into the related problem of the water reuse system planning of Weifang. Starting with the operation cost per year, the author analyzed each part of the operation cost per year thoroughly and carefully. With the object of minniming the system operation cost per year and satisfying the restriction of water quantity, the intact model is established, and solved by using mathematical tool lingo-Third, the author gave some suggestions about expanding the capacity of some sewage treatment plants.It is obvious that the model not only helps to optimizing collocation of resources, but also saves construct and run cost greatly.The result of this paper will help authorities to make decisions about wastewater reuse projects in Weifang and other cities suffering water resources shortage. In in end, allusion to the shortage of this arcicle conents are given, and some research to be further studied are presented.
