| 摘 要： | 采用不主动排泥的运行模式,在相同污泥负荷条件下,对比研究了膜-生物反应器(MBR)与传统活性污泥反应器(CASR)对两种典型内分泌干扰物--双酚A(BPA)与壬基酚聚氧乙烯醚(NPnEO,n=1～4)的去除效果.结果表明,在BPA-污泥负荷与NPnEO-污泥负荷分别为0.046～10.2 g·kg-1·d-1与0.097-0.701 g·kg-1·d-1的范围内,MBR与CASR均能有效去除这2种内分泌干扰物.随着运行时间的延长,污泥对目标物质的去除能力逐渐加强;相比CASB,MBR对目标物质的去除更强且稳定.在获得相同的出水目标物质浓度条件下,MBR可以耐受更高的容积负荷.2种内分泌干扰物的投加对MBR和CASR的COD和NH4-N的去除均没有明显影响.
