中文摘要 | 本研究使用H2O2/UV高級氧化程序處理垃圾滲出水,以期了解是否能夠取代原有之逆滲透處理程序。水樣來源為衛生掩埋場經生物處理、混凝沈澱及初過瀘之廢水。經分析後得知,pH接近中性偏酸,具高導電度(19.3mS/cm),呈現深褐色之高色度(ADMI=6897色度單位),含大量有機成份(COD=3331MG/l),具多量之氯鹽(6392mg/L),並存有鹼度(828mg/L)。由本程序處理後之分析結果得知,色度之去除率達95%,但COD之去除則有美僅18%。此外,H2O2最好能以一次添加為宜,分次添加並無法改善其處理效率。 |
英文摘要 | This paper describes the treatment of landfill leachate by using H2O2 /UV oxidation process. The focus is to understand the feasibility of replacing the existing reverse osmosis process with the H2O2/UV process. The water samples were taken from the effluent, which has been treated by a process train including biological, chemical coagulant, and sand filter units. Such an effluent has a pH near neutral condition, high conductivity (19.3mS/cm), and high contents of color (6897 in ADMI unit), organics (COD = 3331 mg/L), chloride (6392 mg/L), and alkalinity (828 mg/L as CaCO3). After H2O2/UV treatment, this process is able to remove color and COD by 95% and 18%, respectively; the removal efficiency of COD is much lower than that of color. In addition, it was found that step additions of H2O2 do not improve the treatment performance, hence, it is suggested to apply the H2O2 dosage initially at one step. |
