摘　　要：厌氧颗粒污泥的培养和保持是厌氧反应器使用中的大问题,水力条件则是影响颗粒污泥状态的重要因素之一。对外循环厌氧反应器和EGSB(Expanded Granular Sludge Bed)反应器中水力混合特性的对比研究发现,外循环厌氧反应器比EGSB反应器有更好的水力条件,离散率更高,并且反应器内的死区减少,从而有利于厌氧反应器内颗粒污泥的生长和更有效的去除污染物。Cultivation and maintenance of anaerobic particle sludge are the barriers in the usage of anaerobic reactor and hydraulic condition is one of the most factors to influence the state of particle sludge.According to the compared research on hydraulic characteristics in outer circulation anaerobic reactor and EGSB reactor,the former has better hydraulic conditions,scatter rate than those of the latter.The outer reactor could mix perfectly,which will benefit for the growth of particle sludge and removal of pollutants.
