Optimization Research Of Incinerated Waste On "Collection-Storage-Transportation" System In Beijing

With the development of economy and urbanization,the number of municipal solid waste is growing rapidly,which made the urban development facing enormous waste disposal pressure.Compared with other treatment methods,the waste incineration has outstanding advantages in waste reduction and resource utilization,attracting more and more attention.At present,the cost and emission of waste incineration in China is too high,and in Beijing the problem is also serious.We analyzed the collection and transportation of municipal solid waste in Beijing,and found that mixed transportation still is the main form of garbage transport.The mixed transportation seriously affects the classification of garbage,which is the main cause of the problem in waste incineration.In order to improve the effect of garbage disposal,this thesis takes the Xuanwu District of Beijing as the research object,analyzing the incinerated waste transportation.According to the current situation,this thesis establishes the optimization model of collection and"storage-transportation" for incinerated waste under the condition of classified collection and transportation.Combined with the existing facilities and treatment situation,this thesis researched the mode of garbage classified collection and transportation.The main research contents include the following three points.Firstly,this thesis utilized the literature method to review the situation of generating electricity through waste incineration at home and abroad.Meantime,the field research method was utilized to understand the situation of municipal solid waste collection and transportation.Secondly,we optimized the function of the garbage collection and transportation station.Based on the existing layout and the amount of collected garbage of each stations in Xuanwu District of Beijing,this thesis optimizes the number of stations and eliminates the station with lower garbage collection amount.On the basis of this,the function of the station for collecting incinerated waste or kitchen waste was studied under the goal of minimum the transportation volume.Finally,combined with the garbage storage time in station,this thesis optimized the path of garbage transportation vehicles.The impact of station on the environment increases with the garbage storage time.In order to reduce the environment impact,we added the garbage storage time in station into the truck transportation route optimization model with the goal of minimizing transportation distance and the garbage storage time.The garbage collection and transportation by station can effectively reduce the mix of garbage and realize the scaled benefits of garbage transportation.The classified collection and transportation is the basis of garbage recycling.The research on garbage classified transportation and collection mode has certain practical and theoretical significance.
