High concentrations cause color and organic contamination problems. Even NOM is not toxic, however, NOM will form disinfection by-products such as trihhalomethane and haloacetic acid after chlorination. THMs are the predominant contaminants which can cause urinary and ingestion cancers and pose adverse effects on reproduction system. Because their complex structure and bio-recalcitrance of NOMs, the conventional wastewater treatment processes like coagulation or activated sludge process. Advanced oxidation processes including O3, O3/UV, Fenton oxidation and photo-Fenton. Even though, AOPs can effectively remove NOM, its high costs may limit its application. Fe0/air is an innovative, low-cost technique. In the aerobic and acidic conditions, hydroxyl radicals and ferryl ions generated through iron corrosion can oxidize the organic matters. However, the studies on NOM removal by Fe0/air process are rare. Usually, the parameters including color, COD, TOC, UV254, GC/MS and THMFP are employed to evaluate the effectiveness of processes on NOM removal. However, the studies on acute and mutagenic toxicity of the AOP- and Fe0/air-treated NOM solution and the chlorination-treated effluents are limited. Humic acid is the majority of NOM. The humic acid and aged leachate are selected as the target compound in this study. The optimal operation parameters and removal efficiency of O3, O3/UV, Fenton, photo-Fenton, Fe0/air, Fe0/air/UV are investigated. Additionally, the cost analysis of different processes is conducted. The color, COD, TOC, UV254, GC/MS, Microtox test and Ames test are measured. Then, the effluent from biological treatment of aged landfill leachate is also testedThe color, COD, TOC, UV254, GC/MS, Microtox test and Ames test are measured. The optimal parameters obtained from above NOM treatment are employed.許多廢水含高濃度天然有機物(natural organic matter,NOM)包括紙漿廢水及滲出水生物處理單元 出流水。NOM 主要成份之一為humic acid,高濃度humic acid 除會造成造成色度及有機污染問題外, 其經氯消毒會產生致突變性消毒副產物(disinfection by-product, DPB)如三鹵甲烷(trihalomethane)及鹵 乙酸(haloacetic acid)等,進而衝擊生態環境,另會危害居民健康如泌尿消化系統癌症及生殖系統傷害。 Humic acid 因其構造複雜及難生物分解,不易以傳統廢水處理程序如混凝沉澱及活性污泥程序去 除。近年來AOPs 包括Fenton, photo-Fenton, O3, O3/UV 等已常應用於humic acid 去除,但因其處理成 本高,經濟成本上較為不可行性。Fe0/air 法為一新穎低成本綠色處理技術,可用氫氧自由基及ferryl ion 及產生鐵離子有效去除有機物,但目前針對腐植酸去除研究較少。另目前對於humic acid 處理成效評 估主要以色度、COD、TOC、UV254、中間產物及THMFP 等項目為主。但對於各種處理單元之出流 水經氯消毒後急毒性及致突變性研究較少。 本研究主要目的為評估Fe0/air 及Fe0/air/UV 對humic acid 處理成效,並與O3/UV 與photo-Fenton 法處理humic acid 能力進行比較,要評估項目色度、COD、TOC、UV254、THMFP、零價鐵循環再利 用、生物毒性(Microtox test 及Ames test)及成本效益分析。本趼究亦將選取一處垃圾滲出水生物處理 單元出流水,評估Fe0/air、Fe0/air/UV, O3/UV 與photo-Fenton 法對色度、COD、TOC、UV254、急毒性 及致突變性去除情形,同時進行成本效率分析。腐植酸零價鐵生物毒性THMFPphoto-FentonozonationUVFe0air成本效益分析Humic acidzero-valent ironbiotoxicityTHMFPphoto-FentonozonationUVFe0aircostanalysis低價零價鐵對腐植酸去除及氯消毒產物毒性評估Project
