摘 要: 为了获得高效的有毒选矿药剂浮选废水的处理工艺，率先开展利用膜生物反应器(sMBR)技术来处理含苯胺黑药选矿废水，研究不同水力停留时间和不同进水药剂初始浓度对sMBR系统的处理效果影响，并考察不同进水药剂浓度对系统污泥产生的影响。结果表明：水力停留时间的延长有利于系统的处理效果的提高，经济有效的水力停留时间为3 h；高浓度苯胺黑药对系统的COD去除效果有抑制作用，同时对系统污泥的浓度和活性有一定的抑制作用。sMBR在水力停留时间为3 h的条件下稳定运行，在此条件下处理不同进水药剂浓度的COD去除率大于80%。

Abstract:To find a high efficient toxic floatation reagents wastewater treatment technology, submerged membrane bioreactor (sMBR) was used to treat with simulated aniline aerofloat wastewater for the first time. The effects of hydraulic retention time (HRT) and aniline aerofloat concentration on treatment efficiency of aniline aerofloat were investigated. And the effect of aniline aerofloat on activated sludge of sMBR was studied. The results show that extension of HRT is beneficial to aniline aerofloat degradation and 3 h is the economic HRT. Aniline aerofloat concentration has inhibitory effect on COD removal of the system and high concentration aniline aerofloat can inhibit the active of activated sludge. During stable operation under the optimal operation condition, COD removal rate is more than 80% under different influent concentrations. And the system maintains stable treatment efficiency.
Key words: submerged membrane bioreactor; aniline aerofloat flotation wastewater; hydraulic retention time; treatment efficiency; active sludge
