摘　　要：本实验把筛选的异养菌黄单胞菌He4和自养菌排硫杆菌Au16,接种到生物滴滤塔中进行脱除乙硫醇研究。结果表明 ,乙硫醇进气流量为 0 3、 0 6和 1 2m3/h ,进气浓度分别为 118、 64和 31mg/m3时 ,乙硫醇出气浓度不高于 1mg/m3。系统中乙硫醇的最佳质量负荷不宜高于 4 0mg/kg填料·h。喷淋量在负荷一定时 ,进气流量越高 ,所需喷淋量越大。喷淋液的最适温度应控制在 2 5～ 30℃左右。喷淋液的SO2 - 4浓度不宜高于 4 0 0mg/L。The screened bacteria of Xanthomonas sp He4 and Thiobacillus thioparus Au16 were inoculated into the trickled-bed biofilter to remove ethanethiol gas in the experiment. Effluent malodor concentration is less than 1 mg/m3 when gas flow rateis 0.3,0.6 or 1.2 m3/h and influent malodor concentration is 118?64 or 31mg/m3 respectively. The optimal odors quality load should be no more than 40mg/kg filter·h. The higher gas flow rate is, the more spray liquid is needed in the constant load. The suitable temperature of the system is 25～30℃. If the concentration of SO4 2- in the spray liquid is over 400mg/L, deodorization efficiency willdecrease obviously.
