【摘要】 卫生填埋场场址的优劣很大程度上决定其工程投资的大小,因而如何科学合理地选择场址就成为人们关注和研究的热点。鉴于卫生填埋场在我国城市生活垃圾处置中的独特优势,本论文以铁路垃圾为切入点,通过资料调研、现场调查和计算分析,对铁路垃圾卫生填埋场选址方法进行研究,取得了较为满意的成果,有助于拓宽卫生填埋技术的应用范围和丰富选址的方法,同时可为城市垃圾卫生填埋场的选址提供指导和参考。 本论文通过对已有选址方法的系统总结,基于对卫生填埋场选址影响因素和指标的综合分析,在借鉴国内外有关卫生填埋场选址的最新研究成果的基础上,从理论上阐述了适用于铁路垃圾卫生填埋场选址的多目标决策密切值法、物元决策分析法以及多目标决策模糊优选法的基本原理,建立了一个开放性的选址指标体系。结合算例采用符合我国传统思维习惯的二元互补性比较模糊决策分析方法来计算各个指标的二级权重值,为选址指标由定性向定量转化提供科学依据。根据三种不同的铁路垃圾卫生填埋场选址方法,分别运用了三种不同的转化方法,对选址指标的正向(数值越大越好)和逆向(数值越小越好)进行不同的转化,开发出一个MatLab程序使得密切值法的运用更为简捷。最后把三种选址方法分别用于隆纳铁路垃圾卫生填埋场的三个备选场址的优选,结果表明三种方法所得到的最优场址及其优劣排序均一致,并且与选址专家组推荐的场址相同,由此可见本论文所采用的三种铁路垃圾卫生填埋场的选址方法是可行的,具有推广应用价值。
【Abstract】 The sanitary landfill location decides the engineering investment in great part, so how to select the sanitary landfill site scientifically and reasonably becomes a research focus. In concern with the specific advantages of sanitary landfill for municipal solid waste(MSW) treatment, this thesis takes the railway garbage as an example, carries out research on railway garbage sanitary landfill site selection methods through information research, site investigation and calculation analysis. The research results help to enlarge the application scope of sanitary landfill and site selection methods, and offer directions for MSW sanitary landfill site selection.Through systematic conclusions of site selection methods and complicated analysis of site selection influence factors and index, based on the newest research results of sanitary landfill site selection both at home and abroad, this thesis discusses the elementary principles of multi-objectives decision osculating value method, matter element analysis method and multi-objectives decision fuzzy optimization method, builds an open site selection index system. The calculation example takes the traditional thought habit-the duality complementarily fuzzy decision method to decide the second grade weight of site selection index. The method offers the scientific support for the transformation from the qualitative index to quantitative index. According to the three deferent site selection methods, this thesis takes three transformations. The positive transformation (the numerical value larger, the result better) and the negative transformation (the numerical value smaller, the result better) are all included. A Matlab program is developed to predigest the osculating value method. The three site selection methods are used in the optimization selection of the Longchang-Naxi railway sanitary landfill site. The result suggests that the best site and the selection order are accordant with the result that the specialist group recommends, which proves that the three site selection methods recommended in this thesis are suitable for application.
