Research On The Evaluation Of Small Town’s Municipal Solid Waste Treatment Technology In Yunnan Province

With the rapid development of China’s small cities and towns, the quality of the living environment of urban residents also put forward higher requirements. Living garbage disposal problems of small town as the current process of urbanization in the hot issues, more and more attracts people’s attention. The study of small town’s waste is more and more. At present, China’s small towns are mainly garbage piled up at random based, basically in a state of disorder. A lot of farmland occupation garbage, garbage Siege causing widespread phenomenon, plastic packaging materials and plastic sheeting caused by a large number of "white pollution" problem is very serious. Similarly, the province facing the problem of waste disposal is also more prominent. Most small towns in the province is still in the early stages of development economics, waste disposal work started late, the overall low level of technology, coupled with the lack of systematic long-term planning guidance and funding of special difficulties, such as garbage disposal facilities completely unable to meet small the practical needs of urban development. So, if not a good solution to small town living garbage disposal problems, it will affect the healthy development of small towns, and even affect the national strategic development as a whole.Currently, more mature technologies include solid waste disposal landfill, composting, incineration and comprehensive treatment of the four treatment technologies have advantages and disadvantages when it comes to small towns when selecting the actual circumstances, will face a very difficult work. However, to achieve waste "harmless, reduction, recycling", you must select the appropriate local phase, taking into account economic, technical, environmental, social and other factors, waste disposal technology. Therefore, the small town garbage disposal technology evaluation studies, it is particularly important.Firstly, this article analysis depth garbage disposal in Small Town of the current situation, pointed out the small town of Yunnan waste problems. Through the current impact of solid waste disposal technology and small town garbage disposal technology options for a comprehensive analysis of the factors in the economic, technical, environmental and social aspects of a total of15evaluation indicators selected to build small towns in Yunnan garbage disposal technology evaluation index system. The total investment of the economic indicators, unit operating costs, payback period, ROI, land tenure; technical indicators technical reliability, siting requirements, processing object requirements, operation and management requirements; environmental indicators have direct contamination of the environment, the secondary pollution (cross-media pollution), health and safety assessment; social indicators have resource assessment, reduction effects, public satisfaction.In this paper, fuzzy mathematics, but treatment can’t be quantified objectively existing indicators, to build a complete fuzzy comprehensive evaluation model. Avoid using AHP expert scoring method commonly used in the subjectivity factor to determine the weight of each index, derived fit in Small Town garbage disposal technology, fuzzy comprehensive evaluation model. Its significance lies through this model, you can Yunnan existing waste disposal technology to optimize the upcoming construction of the future waste disposal facilities in small towns provide valuable reference and reference. Finally, The garbage dump of Guangtong small town in Yunnan to be built as an example, the application of fuzzy comprehensive evaluation model for analysis and processing, Good for wide pass the town garbage dump processing techniques for the landfill conclusions.Present research on the sanitary landfill, composting, incineration and comprehensive treatment of the four treatment technologies have some evaluation studies, but most of them are qualitative, descriptive language evaluation. And most of the cities as the research object garbage, garbage on the small town of few. Research methods, most of the life-cycle approach is used, AHP, etc., without the use of AHP to determine index weight, combined with fuzzy comprehensive evaluation method, therefore, this article in the selection of economic, technical, environmental and social and other aspects of15major indicators establish evaluation index system, on the AHP determine the index weight, combining fuzzy mathematics fuzzy comprehensive evaluation model, have a certain degree of innovation.
