内循环生物流化床反应器载体挂膜特性的研究

BIOFILM FORMATION IN INTERNAL LOOP BIOFLUIDISED BED

分别考察了水力停留时间、反应器结构、接种污泥量及载体粒径等因素对内循环三相生物流化床反应器载体挂膜的影响．试验结果表明，较短的停留时间、较小的内循环速度、较少的接种污泥量及较小粒径的载体有利于反应器的快速挂膜启动．

The effects of hydraulic retention time,reactor structure, sludge inoculation concentration and carrier size on biofilm formation on carrier surface in an internal loop biofluidised bed were studied.The results show that shorter HRT, Smaller internal circulation velocity,inoculation concentration and carrier size can be beneficial to the rapid biofilm formatiion and the stat up of the reactor.
