本研究探討滲出液經Fenton’s氧化法處理,再以活性碳進行吸附調查污染物之去除效果。吸附管柱狀高為100公分,內徑為20公分,試驗滲出液由上流下於底部收集進行污染物濃度分析。 實驗結果顯示化學需氧量、色度、氨氮與鈣/鎂等分別於10、30、40與8床體積時,可達吸附飽和。重金屬吸附強度為Cd > Pb > Cr > Zn > Ni > Cu。吸附流出之水質經Microtox test進行毒理分析得知其均未達EC50之範圍。研究結果顯示活性碳具吸附金屬、色度、化學需氧量與氨氮等之潛勢,其吸附後之放流經Microtox test測試對環境毒理尚未達影響程度。
This study aims at investigating the effects of MSW incinerator fly ash (FA) and bottom ash (BA) on the anaerobic co-digestion of OFMSW with FA or BA. It also simulates the biogas production from various dosed and control bioreactors. Results showed that suitable ashes addition (FA/MSW 10 and 20 g L-1 and BA/MSW 100 g L-1) could improve the MSW anaerobic digestion and enhance the biogas production rates. FA/MSW 20 g L-1 bioreactor had the higher biogas production and rate implying the potential option for MSW anaerobic co-digestion. Modeling studies showed that exponential plot simulated better for FA/MSW 10 g L-1 and control bioreactors while Gaussian plot was applicable for FA/MSW 20 g L-1 one. Linear and exponential plot of descending limb both simulated better for BA/MSW 100 g L-1 bioreactor. Modified Gompertz plot showed higher correlation of biogas accumulation than exponential rise to maximum plot for all bioreactors.
