The Study Of Rural Sewage Treatment Plan Optimization Based On GA-BP

Along with the further development of the new countryside construction and the ruralgovernment and farmers improving the consciousness of protecting enviormennt, thedemand of rural domestic sewage facilities was increasing year by year, the level of thesewage treatment facilities construction was improving step by step. But at present therual domestic sewage treatment facilities on the whole existed the phenomenon of buildup,no use. The reasons of the phenomenon were very complex,for example, lacking ofthe relevant design standards conforming to rural characteristics, the selection of ruralsewage disposal engineering design was not enough reasonable,rural sewage treatmentfacilities cost too much and the management was difficult. In view of the above question,this article had studied the optimization of rural sewage treatment design scheme incombination with the project.The research mainly divided into the following several parts:(1) According to analysise the factor which influence the optimization of ruralsewage treatment design scheme from engineering economy, engineering technology andproject management, this paper had chosen the thirteen factor which were most important.And then the article had established the rural sewage treatment plan optimization indexsystem and rural sewage treatment plan optimization classification basic value evaluationindex in line with existing national standards and design standard.(2) Using the method of GA-BP, this paper had constructed the rural sewagetreatment plan optimization model, including sample data generation, the nodes number ofthe BP network hidden layer, genetic algorithm parameters, etc.(3) Developing the graphical user interface of the model based on GA-BP neturalnetwork. Through the user interface, user could solved optimization problem using GA-BPneural network model in the case of not familiar with Matlab software.(4) Case study. The paper had studied the rual sewage treatment project of YaHe ascase using optimization evaluation model and software. The research results verified thefeasibility.Research results show that the proposed rural sewage treatment plan optimization evaluation index and measurement method is reasonable, the establishment of GA-BPneural network rural sewage treatment plan optimization model is practical, the model ofthe development of the graphical user interface is friendly and easy operation.
