摘　　要：采用MBR系统和PAC-MBR系统去除水中的内分泌干扰物阿特拉津,结果表明,PAC-MBR系统对阿特拉津的去除率达到54.16%,明显高于MBR系统20.22%的去除率。同时,还研究了不同有机底物浓度和不同进水阿特拉津浓度对出水时阿特拉津去除率的影响。当进水的阿特拉津浓度为0.18、0.1mg·L-1和0.05mg·L-1,水力停留时间2h,出水时MBR系统和PAC-MBR系统对阿特拉津的去除率分别为17.75%、27.32%、38.08%和36.68%、41.23%、42.78%。当进水的有机物浓度为6.6、2.3、0.1mg·L-1时,在相同的水力停留时间下,MBR系统和PAC-MBR系统对阿特拉津的去除率分别为16.71%、20.62%、37.95%和38,76%、40%、40.02%。试验数据说明PAC-MBR系统的抗冲击负荷能力明显优于MBR系统,证实了生物作用在阿特拉津的去除中起主要作用。Membrane bioreactor （MBR） and PAC-MBR have been used to remove the atrazine which is one of the Endocrine disrupting chemicals （EDCs）. The results showed that, a Wazine in PAC-MBR system is 54.16% and it is higher than that of MBR system. Also two factors which influence the e-limination rate of atrazine during water leakage are analyzed in the research. The elimination rates of atrazine are 17.75%, 27.32%, 38.08% of the MBR system under the condition of different atrazine concentrations for 0.18 mg- L^-1, 0.1 mg- L^-1 and 0.05 mg. L^-1 in the raw water and 2 h of hydraulic retention time. And the elimination rates of atrazine are 36.68%, 41.23%, 42.78% of the PAC-MBR system under the same condition. The elimination rates of atrazine are 16.71%, 20.62%, 37.95% of the MBR system under the condition of different concentrations of organic for 6.6 mg-L^-1, 2.3 mg .L^-1 and 0.1 mg-L^-1 and the same hydraulic retention time. And the elimination rates of atrazine are 38.76%, 40%, 40.02% of the PAC-MBR system under the same condition. The results indicate that anti-impact elevating capacity of the PAC-MBR is better than the MBR system obviously. Also it confirmed that the biological action is the main factor in the elimination of atrazine.
