摘要
在常温条件下,以陶粒和悬浮改性填料WD-F10-4为填料的生物滴滤塔系统对硫化氢废气进行净化处理,考察了不同硫化氢负荷、营养液喷淋量和气体停留时间对生物滴滤塔性能的影响。实验结果表明,当进气质量浓度为400 mg/m3,硫化氢负荷为32 g/(m3·h),喷淋量为4 L/h,气体停留时间为46 s,系统的平均去除效率为97%。系统运行期间,填料未出现堵塞现象,证明悬浮改性填料可用作生物滴滤塔的填料。
Ceramsite and suspending modified packing material WD-F10-4 are used to immobilize activated sludge in a biotrickling filter for removal of hydrogen sulfide (H2S) at room temperature.The effects of different load of H2S,rate of spray nutrient and empty bed residence time(EBRT) on the performance of biotrickling filter are studied.The average removal efficiency of H2S is 97% under the following conditions:32 g/(m3 ·h) of the load,400 mg/m3 of inlet concentration,4 L/h of rate of spray nutrient and 46 s of EBRT.During the operation period,the system does not block,which indicate that suspending modified packing material WD-F10-4 is suitable to be used as packing material in biotrickling filter.
