摘　　要：本文采用复合生物反应器对甲醛废气的净化性能进行了实验研究,考察了进口气体浓度和气体流量的改变对甲醛净化性能的影响。结果表明:当pH值控制在6~8、气体流量为400 L/h、循环液流量为10 L/h、甲醛进口气体浓度为300 mg/m3时,复合生物反应器对甲醛废气有最大净化性能,其最大生化去除量可达到13.70 mg/(L?h)。In this paper, the performance of purifying formaldehyde emission by composite bioreactor was investigated experimentally. The effects of changes in import gas concentration and gas flow rate on formaldehyde purification performance were examined. The experimental results indicated that when the pH was controlled at 6 - 8, the gas flow rate was 400 L/h, the circulating fluid flow rate was 10 L/h, and the concentration of formaldehyde imported gas was about 300 mg/m3, compound bioreactor was biggest for purification performance of formaldehyde emission. The maximum amount of biochemical removal can reach 13.70 mg/(L?h).
