中文摘要 | 目前台灣地區垃圾的處理仍以集體掩埋法為主,本計畫研究包括台灣地 區垃圾滲出水之特性及其處理,以台灣一典型滲出水處理場為實場之研究。其清 運人口為468,051人,垃圾量為483噸/日,滲出水水質:pH=7~9、BOD��/TP(五日的 生化需氧量/總磷)=11~33。滲出水處理場可分兩部分,一為包括曝氣氧化塘與沈 澱池的生物處理.及化學混凝與沈澱池的化學處理;第二部分則為污泥處理。場 內生物處理對BOD(生化需氧量)、COD(化學需氧量)、NH��+-N(氨氮)與TKN(凱氏 氮)之平均去除率較化學混凝之平均去除率為佳;對SS(總懸浮固體物)、VSS(總揮 發性固體物)與TP(總磷)而言,則化學混凝效果較好。若兩者串聯處理之處理效果 對BOD之總去除率為88.8、COD為85、SS為72.6、VSS為71.3、氨氮為88、TKN為 83.3、TP為91.5、Fe(鐵)為76.9-Cr(鉻)為84.4...等。 |
英文摘要 | The disposal of domestic solid wastes in Taiwan are almost exclusively by use of sanitary landfill. The aim of this study was to investigate the properties and methodology fortreatment of landfill leachate. The study was examined in the study of an full-scale leachatetreatment plant. The plant serves a population of 468,051 living in that region, as well as solidwastes are 483 tons/day. The analyses of leachate showed that the ranges of pH and BOD/TPratio were within 7-9 and 11-33 respectively. The leachate treatment plant contains two parts,one is biological treatment processes consisted of aerated oxidation unit and sedimentation tankand the chemical aided precipitation system, and the other is the treatment of the producedsludges. According to the results of analysis, the biological treatment processes were dominatingfor the removal efficiencies of BOD, COD, NH��+-N and TKN. However, the main removals ofSS, VSS and TP were obtained in the chemical aided precipitation system. When the chemicalaided precipitation system was incorporated into the biological treatment processes, the mainresults obtained are as follow: BOD (~ 88.8), COD (~ 85), SS (~ 72.6), VSS (~ 71.3),NH��+-N (~ 88), TKN (~ 83.3), TP (~ 91.5), Fe (~ 76.9) and Cr (-84.4), etc. |
