苏北A市生活垃圾卫生填埋场工艺设计 班 级： 学生姓名学 号： 指导教师：ABSTRACT With the development of economy ,population,living standards and accelerating urbanization,the amount of waste is also increasing.Due to the great population base,China has become the country with the largest annual waste in the world,and the waste continues to increase in the growth of 9%.So the disposal of municipal waste has raised the focus of the government and people.Currently,there are three methods of municipal waste disposal,including incineration,sanitary landfill and composting.Due to sanitary landfill is simple ,the costs of investment and operating is not too much and no special requirements for waste,etc,it has become the main method of the disposal of municipal waste. According to economic, natural geographic and the comparison of the three methods,we choose sanitary landfill to dispose the waste in A city finally.Because the amount of waste is large,wo decide to build the landfill separately and choose the most suitable land according to the prediction of waste and design standards.During the degradation of waste,landfill leachate and gas is produced ,so we need to build appropriate seepage engineering and drainage system to protect the environment from contamination,and try to dispose and use them well. Keywords:sanitary landfill；horizontal seepage；treatment of landfill leachate；use and guide of landfill gas . 目 录 一、概述 1 1.1工程概况 1 1.2 设计原则与范围 1 1.2.1编制原则 1 1.2.2处理方案选择原则 1 1.3 设计依据 1 1.4 规范和标准 2 二、工程基础资料 2 2.1 城市概况 2 2.1.1地理位置 2 2.1.2社会环境概况 2 2.1.3经济概况 2 2.1.4交通运输 3 2.2 自然条件 3 2.2.1地形地貌 3 2.2.2 气象资料 3 2.2.3 水文地质 3 2.2.4 地震与防洪 3 2.3 A市环境卫生现状和规划 3 2.3.1A市环境卫生现状 3 2.3.2A市环境卫生规划简述 4 2.3.3垃圾量预测 4 2.3.4垃圾处理方式选择 5 三、卫生填埋场厂址选择 6 3.1填埋容积预测 6 3.2填埋场区域确定 7 3.3填埋场类型 7 3.4填埋场等级划分与规模确定 7 3.5 填埋场选址条件 7 3.5.1场址禁设地区 7 3.5.2选址条件 8 3.6场址比选与场址确定 8 3.7场址结论 10 四、卫生填埋场工程设计 10 4.1 填埋物要求 10 4.2填埋库容的计算 11 4.2.1垃圾坝高度的确定 11 4.2.2填埋边坡的设计 11 4.2.3填埋场库容设计计算 12 4.2.4垃圾坝的结构 12 4.2.5垃圾坝坝型 12 4.2.6垃圾
