中文摘要 | 本研究旨在探討不同銅負荷對豬糞尿廢水厭氣處理之影響,結果發現當臥置式厭氣處理槽銅負荷濃度在100 mg Cu/L-d以下時,5週內對沼氣產量及流出液水質無明顯影響;而當銅負荷在200 mg Cu/L-d以上時,對沼氣產量會有抑制現象。進流液中添加銅200、400、600、800 mg Cu/L-d者,其第二週之沼氣產量分別降低至對照組的86%、73%、67%及61%,但自第三週起各組之沼氣產量皆又開始回昇,但是其回復程度隨銅負荷增高而降低,上述各組之沼氣產量最多分別回復至對照組的118%、97%、89%、82%。在流出液水質方面,銅負荷大於600 mg Cu/L-d時,流出液之COD及BOD較對照組顯著增高。流出液中銅濃度隨添加銅週數增加而增加,經5週後,各組流出液之銅濃度分別為18、32、48及52mg/L。在本試驗中發現進流液中91%~93%的銅留存於厭氣污泥中,因此由高銅進流液所產生的高銅污泥之處置問題將會成為另一重要研究課題。 |
英文摘要 | The purpose of this study was to determine the effects of copper at different concentrations on the anaerobic treatment of swine wastewater. A bench-scale horizontal anaerobic fermenter and formulated swine wastewater were used for this study. No significant effects were found on the biogas production and the chemical composition of anaerobic effluent, when the copper loading was less than 100 mg Cu/L-d. When the copper loading was over 200 mg Cu/L-d, the biogas production was reduced. The reduction of the biogas productions at the second week were 86%, 73%, 67% and 61% that of control, as the copper loading were 200, 400, 600 and 800 mg Cu/L-d, respectively. After the second week, the reduction began to recover, but the recovery was lower with the higher copper loading. The high loading of copper (above 600 mg Cu/L-d) significantly resulted in the higher COD and BOD of the effluent. The copper concentration of effluent was getting higher as the copper loading day increased. After 5 weeks of copper loading, the concentrations of copper in the effluent were 18, 32, 48 and 52 mg/L, respectively. During anaerobic fermentation, 91~93% of influent copper was accumulated in the anaerobic sludge. Hence, the disposal of the sludge with high content of copper needs further study. |
