A new bioreactor on the basis of a dynamic fluidized bed was designed, which combines advantages of the fluidized bed and a biological contactor. The experiments of start up, normal operation and parameter adjustment are carried out. The results show that the bioreactor can be quickly started up in the condition that the fill is 50%, the hydraulic retention time is 72 min, aerate speed is 2.5 m3/h, rotation-cage rotated speed is 1.5 r/min, and the removal rates of chemical oxygen demand (CODcr) and Ammonia nitrogen (NH3-N) are 75.34% and 80.98% respectively. The influence of the operation parameter on removal rates of the bioreactor is analyzed, and an appropriate operation parameter is provided. 相似文献

风帽是循环流化床锅炉布风装置的重要部件之一,其主要用途是,在锅炉一次风的作用下将沸腾床内床料充分流化。保证燃料能充分燃烧。我公司使用的风帽结构是无帽头的小风帽,安装在风室水冷布风板上面,一般在锅炉连续运行150天左右就出现风帽头部磨破2/3以上,此时锅炉在运行中出现沸腾床流化不均匀和风室大量积渣现象,需要停炉更换已损坏的风帽。 相似文献
