摘要:
采用填充ZX03型填料的生物滴滤塔处理H2S与C6H5CH2COOH的混合制药废气。主要考察了不同进气浓度比例下H2S与C6H5CH2COOH的去除效率,不同流量下的压力损失及气体停留时间对去除率的影响。结果表明:随着H2S与C6H5CH2COOH进气浓度比例的提高,H2S的去除率均保持在95%以上,C6H5CH2COOH的去除率逐渐下降。当H2S与C6H5CH2COOH的进气质量浓度分别为ρ(H2S)<400 mg/m3与ρ(C6H5CH2COOH)<800 mg/m3,其最佳气体停留时间为30 s。该生物滴滤塔压力损失小,无堵塞现象,可长期稳定运行。
Abstract:
The b io-trickling filter packed w ith ZX03 carrier is used to treatm ix pharmaceut ical gases containingH2 S and C6H5CH2COOH. The remova l efficiency of H2 S and C6H5CH2COOH at various in let concentration rat ios, the pressure drop of the bioreactor at d ifferent gas flow rates and the effect of the gas retention t ime on remova l efficiency are investigated in the experimen.t The resu lts show that the removal efficiency ofH2S remains above 95% regardless of the ratio ofH2 S /C6H5CH2COOH and the remova l efficiency o fC6H5CH2COOH decreases graduallyw ith the elevation of inlet concentrat ion ratio o fH2 S /C6H5CH2COOH. When the in let concentrat ion of H2 S and C6H5CH2COOH is respectively less than 400mg /m3 and 800mg /m3, the optima lgas retention time is 30 s. The b io-trickling filter is not jammed and the resistance is maintained at low va lue during the operat ion. It doesn't need to carry out back w ash ing frequent ly and can be operated steadily for long time.
