The Research On Technology Integration Model And Evaluation Model Of Rural Toilet

Since our country started the work related to the rural "toilet revolution" in 2014,it has made great achievements.However,the natural environment,humanistic characteristics and economic conditions of various regions in China are quite different,The existing toilet technology is difficult to meet the needs of toilet replacement,and there is a lack of standardized toilet technology type selection methods.This article is based on the data of rural toilet renovation in China and is established by the fuzzy comprehensive evaluation method based on AHP The evaluation model of toilet technology selection suitable for rural areas in China is presented.The research conclusion is as follows:(1)This study analyzes the status of toilet renovation in the country through literature surveys and field surveys,and use statistical methods to summarize the original data,compare the differences in sanitation toilet penetration rates in different regions.Analysis shows that the task of toilet renovation in my country is still arduous,toilet technology using single and Various conclusions on the factors affecting toilet renovation.(2)Analyze the existing more mature rural toilet renovation technology,and sort them according to water flush toilets and waterless flush toilets,and summarize the advantages and disadvantages and applicable conditions of each toilet technology.Combined with the regional characteristics of the northwest region,the toilet technology is integrated according to the two methods of toilet construction(collection-storagetreatment)and toilet technology improvement.Get four kinds of toilet technology integration models suitable for the northwest region.They are combined vacuum drainage toilet technology,improved manure and urine diversity toilet technology,improved complete sewer flushing toilet technology and improved three-cell septic toilet technology.(3)Established the evaluation model of rural toilet technology selection.Based on the factors that affect the renovation of toilets in rural China,combining the literature and consulting experts in related fields,sixteen specific evaluation indicators were selected,Establish a selection evaluation index system;Using Fuzzy Comprehensive Evaluation Method Based on Analytic Hierarchy Process to Construct Evaluation Model of Rural Toilet Technology Selection.(4)Take a county in the northwest region as an example.Using the established rural toilet technology selection evaluation model,the four toilet technology models suitable for the northwest region are selected and evaluated,.The evaluation results obtained four kinds of modes of technology,based on the final low scores,improved selection technique three grid septic tank toilets.Demonstration project construction is carried out locally,and the demonstration project is checked and accepted 5 months after the completion of the construction.This proves that the scientific integration method of rural toilet technology and evaluation model of rural toilet technology selection are scientific and practical.
