摘要
实验室研究表明 ,利用矿化垃圾作填料的生物反应床在厌氧条件下可有效地处理NO废气。气体在反应床中的停留时间是影响NO处理效率的关键参数 ,NO去除率随着停留时间的缩短而降低。添加菌种可缩短生物反应床启动时间。厌氧条件下NO去除效果明显要好于好氧条件下的试验 ,利用微生物的反硝化作用处理NO_x 比生物硝化作用更具优势。
Stabilized or aged refuse is a good media for bioreactor and can be used to treat NO X in waste gas streams.Laboratory study shows that an aged refuse based bioreactor can effectively remove NO from waste gas streams.The empty bed retention time (EBRT) is the key parameter effecting the removal efficiency of NO which decreases with the shortening of EBRT.The removal efficiency of NO is 90% with the EBRT of 3.8 min and 96% at 7.5 min. The removal efficiency of NO under anaerobic condition is better than that of aerobic condition.Denitrification of NO is preferable to the biological nitrification of NO.
