白腐菌生物强化活性炭深度处理造纸废水

探讨了黄孢原毛平革菌和红假单胞菌生物强化活性炭对造纸废水色度、COD的去除效果。结果表明,只投加1%黄孢原毛平革菌时,在处理时间180 min后造纸废水的脱色率达80%以上,CODCr去除率达65.1%;只投加1%红假单胞菌脱色效果较差,但CODCr去除率为71.4%;两种菌体组合投加造纸废水,脱色率随着时间的延长可达到90%以上,CODCr去除率均高于单一菌种的效果,达80%左右,其中先经红假单胞菌后经黄孢原毛平革菌生物强化活性炭的组合对造纸废水CODCr去除率高于先经黄孢原毛平革菌后经红假单胞菌生物强化活性炭的CODCr去除率。

Tertiary Activated Carbon Treatment of Papermaking Wastewater Reinforced with White Rot Fungi

The removal efficiency of colourity and COD_Cr of papermaking wastewater treated by reinforced activated carbon with Phanerochaete chrysosporium and Rhodopseudomonas were studied. The results indicated that with only 1% Phanerochaete chrysosporium, the colourity removal rate achieved 80% in 3h, and COD_Cr removal rate was 65.1%, with only 1% Rhodopseudomonas, the colourity removal rate was the lowest, the COD_Cr removal rate was 71.4%. On the other hand colourity removal rate was higher than 90% and COD_Cr removal rate was 80%, higher than only using one of the strains, when the combined strains were used. COD_Cr removal rate of the biological activated carbon technique strengthened by Rhodopseudomonas first than by Phanerochaete chrysosporium was higher than that strengthened by Phanerochaete chrysosporium at first.
