中文摘要 | 微生物固定化在廢水處理上有許多的優點,包括易於製備、污泥體積小而不易膨化等優點,而以海藻膠、洋菜等天然材料作為固定化擔體,較合成材料而言,更具有微生物易於著生、最終分解佳等優點。因此本研究利用海藻酸鈣及聚氨酯泡棉(PU),對白腐菌Phanerochaete chrysosporium 與Trametes versicolor進行固定化,處理硫酸鹽紙漿漂白廢水,比較懸浮培養系統及以天然材料、合成材料為擔體之固定化系統之處理效能,探討微生物固定化在應用於白腐菌處理漂白廢水之可行性。由實驗結果顯示,固定化系統,可維持較久的脫色能力。而以海藻酸鈣固定的白腐菌Phanerochaete chrysosporium 與Trametes versicolor,對製漿廢水COD在第七天有79.4%及85%的去除率,高於同時間自由生長的菌體COD去除率76%及81%,因此本研究証明固定化微生物處理製漿廢水有很高的可行性。 |
英文摘要 | Microbial immobilization has several advantages for wastewater treatment, which includes ease preparation, low volume and stable sludge generation. Natural materials serving as the immobilized carriers, like marine algae and agar, are more easily adhered and degraded by microorganism than synthetic media. This study employed Ca-alginate and polyurethane (PU) foam to immobilize the white rot fungi, Phanerochaete chrysosporium and Trametes versicolor, in the treatment of kraft pulp bleaching effluents. Decolorization efficiencies of effluents were compared among suspended culture system, immobilization by Ca-alginate and PU. Then the feasibility of microbial immobilization by the white-rot fungi employed in bleaching effluents was discussed as well. Experimental results showed that the microbial immobilization could sustain longer decolorization periods than ones of suspended culture system. Ca-alginate immobilized Phanerochaete chrysosporium and Trametes versicolor removed 79.4% and 85% COD from bleaching wastewater at the seventh day, compared to 76% and 81% COD removed by free fungi. Hence, it is demonstrated that the microbial immobilization is highly feasible to treat the bleaching wastewater for discoloration and COD reduction. |
