摘　　要：以去除生物膜填料塔净化甲醛废气时溶解在喷淋液中的甲醛为对象,研究了在喷淋液中加入亚硫酸钠对甲醛净化用生物膜填料塔中优势菌的影响.实验结果表明:亚硫酸钠对生物膜细菌生长具有较好的促进作用;亚硫酸钠提高了生物膜填料塔对甲醛的净化效率;生物膜细菌优势菌仍为假单胞菌属.A biotrickling filter was used to biodegrade formaldehyde gas, and sodium sulfite was applied to remove the formaldehyde solved in the recirculating trickling liquid. The effect of sodium sulfite on the dominant microorganism in the filter was studied. The results showed that sodium sulfite could enhance the growth of the dominant microorganism and improve the removal efficiency of formaldehyde, and the dominant microorganism in the filters was Pseudomonas bacteria.
