摘　　要：采用浸没式管式膜生物反应器处理含酚废水,对不同操作条件下的出水通量进行研究,结果表明,随着膜管内曝气量的增加膜通量衰减程度降低,能保持更高的膜通量;随着污泥浓度的增加,膜仍有较高的通量,当污泥浓度为15.2g·L-1时,膜通量可维持在60L·m-2·h-1;通过连续和间歇出水运行试验对比,发现间歇出水运行膜通量相对较高,通量衰减较慢,运行8h后通量仍能维持在70L·m-2·h-1以上。Phenol wastewater were treated with submerged tubular membrane MBR,the performance of membrane were tested by membrane flux under different operation conditions.It demonstrated that the decline of membrane flux decreased with the increase of aeration rate inner membrane tubular; With the increase of sludge concentration the membrane flux were also high,it kept at 60 L·m^-2·b^-1 when the sludge concentration was 15.2 g .L^-1; Compared to the continuous effluent, the membrane flux of intermittent effluent was higher, decline of membrane flux was slower, the value of membrane flux can maintain at 70 L·m^-2·b^-1 after operating 8 h.
