According to econo mic, natural geographic and the co mparison of t he three methods,w e choose sanitary landfill to dispose the w aste in A city the a mount of w aste is large,w o decide to build the landfill separately and choose the most suitable land according to the prediction of w aste and design the degradation of w aste,landfill leachate and gas is produced ,so w e need to build appropriate seepage engineering a nd drainage syste m to protect the environment from conta mination,a nd try to dispose and use them w ell. Ke ywords: sanitary landfill; horizontal seepage; treatment of landfill leachate;use and guide of landfill gas . 中國礦業(yè)大學 2020 屆本科生畢業(yè)設計 第 4 頁 目 錄 一、概述 ..................................................................................................... 錯誤 !未定義書簽。 工程概況 ....................................................................................................................... 7 設計原則與范圍 .......................................................................................................... 7 編制原則 ............................................................................................................ 7 處理方案選擇原則 ............................................................................................ 7 設計依據(jù) ...................................................................................................................... 7 規(guī)范和標準 .................................................................................................................. 8 二、工程基礎資料 ..................................................................................................................... 8 城市概況 ...................................................................................................................... 8 地理位置 ............................................................................................................ 8 社會環(huán)境概況 .................................................................................................... 8 經(jīng)濟概況 ............................................................................................................ 8 交通運輸 ............................................................................................................ 9 自然條件 ...................................................................................................................... 9 地形地貌 ............................................................................................................ 9 氣象資料 ........................................................................................................... 9 水文地質 ........................................................................................................... 9 地震與防洪 ....................................................................................................... 9 A 市環(huán)境衛(wèi)生現(xiàn)狀和規(guī)劃 ............................................................................................ 9 市環(huán)境衛(wèi)生現(xiàn)狀 ............................................................................................. 9 市環(huán)境衛(wèi)生規(guī)劃簡述 ................................................................................... 10 垃圾量預測 ...................................................................................................... 10 垃圾處理方式選擇 .......................................................................................... 11 三、衛(wèi)生填埋場廠址選擇 ....................................................................................................... 12 填埋容積預測 ............................................................................................................. 12 填埋場區(qū)域確定 ......................................................................................................... 13 填埋場類型 ................................................................................................................. 13 填埋場等級劃分與規(guī)模確定 ..................................................................................... 13 填埋場選址條件 ........................................................................................................ 13 場址禁設地區(qū) .................................................................................................. 13 選址條件 .......................................................................................................... 14 場址比選與場址確定 ....................................................
