摘要
分别采用污水厂剩余污泥的干馏产物——污泥生物炭和目前市场上广泛使用的竹炭填料，在不同的进气浓度、停留时间下开展了除臭对比试验。结果表明，生物炭是一种优良的除臭填料，在较短停留时间下，其对中、高浓度硫化氢气体的去除效果要优于竹炭，生物炭填料更适用于处理较高浓度的臭气。在停留时间为15s的情况下，当进气硫化氢平均浓度接近70mg／m3。时，对其去除率接近86％；当停留时间提高到30s时，生物炭填料对各种浓度硫化氢（O～150mg／m3）的去除率都在92％以上。
A comparison test for odor removal was performed using sewage sludge biocarbon and bamboo charcoal at different inlet concentrations and residence times. The experimental results indicated that the sewage sludge biocarbon was an effective filter material for odor removal. Under the condition of short residence time as well as medium and high concentrations of hydrogen sulfide gas, the treatment ef- ficiency of the sewage sludge biocarbon was higher than that of the bamboo charcoal, especially dealing with high concentrations of odor. The removal rate of hydrogen sulfide was close to 86% at an average in- let concentration of around 70 mg/m3 and residence time 15 seconds. Additionally, the removal rates of hydrogen sulfide would be higher than 92% at different concentrations of 0 to 150 mg/m3 by the sewage sludge biocarbon when residence time rose up to 30 seconds.
